How to build a website like Viator

What is Viator and how does it work?

Viator is a global marketplace for tours, activities, and attraction tickets, connecting travelers with local operators in more than 1,500 destinations. Travelers browse experiences by location, date, and category, then book instantly through the site or app. Operators list their tours, manage availability, and receive bookings without running their own e-commerce infrastructure. TripAdvisor acquired Viator in 2014 for roughly $200 million and now reports Viator-branded "Experiences" revenue inside its Viator and TripAdvisor-branded segments, which together reached about $913 million in 2023 (Tripadvisor 10-K FY2023).

The platform lists more than 300,000 bookable experiences from tens of thousands of operators worldwide, ranging from skip-the-line museum tickets to multi-day trekking packages. Viator's core mechanic is straightforward: it aggregates fragmented, hard-to-find local supply and makes it searchable, bookable, and comparable in one place, then takes a cut of every transaction.

How Viator makes money

Viator earns revenue primarily through commissions charged to tour and activity operators, generally cited in the 20-30% range depending on volume, category, and exclusivity arrangements (Samba HQ). The operator sets a retail price, Viator adds its margin (or takes a cut from within that price), and the traveler pays the total at checkout. Because Viator only earns when a booking completes, its incentives point toward more bookings, which means promoting well-reviewed, well-priced, high-conversion listings over the rest.

Beyond core commissions, Viator sells operators visibility: featured placement in search results, badges like "Likely to Sell Out," and promotional slots during peak booking windows. It also runs an affiliate and API partner program that lets travel agencies, hotel chains, and content sites embed Viator's booking engine and earn a referral cut, extending distribution beyond viator.com itself.

Its relationship with parent company TripAdvisor adds a second growth lever: TripAdvisor's review content and destination pages funnel traffic directly into Viator's booking flow, letting the two brands share acquisition costs that a standalone experience marketplace would have to cover alone.

What makes Viator work: key features

Real-time availability calendars. Every listing shows live capacity by date and time slot, synced against operator-side booking systems so travelers never see a spot that's already sold. This is the single hardest technical problem in experience marketplaces and the one most vibe-coded prototypes skip entirely.

Instant confirmation for most listings. Viator prioritizes "instant confirmation" experiences over "request to book," because travelers overwhelmingly prefer certainty, especially when booking a day or two ahead. Operators who can guarantee capacity get better placement as a result.

Layered review and rating data. Reviews are broken into category scores (guide quality, value, organization) rather than one star rating, giving travelers enough texture to choose between ten similar city tours in the same destination.

Free cancellation as a default filter. Because travelers commit to a fixed date weeks in advance, flexible cancellation policies (typically 24 hours before start time) are treated as a first-class search filter, not a footnote in the listing.

Mobile ticketing and offline access. Confirmed bookings generate QR or barcode tickets that work without a signal, which matters when travelers are standing at a meeting point in a foreign city with limited data.

Multi-currency, multi-language checkout. Prices localize automatically to the traveler's currency and language, removing a major source of cart abandonment for an international audience.

Operator dashboards and business intelligence. Providers get booking pace data, review trends, and pricing suggestions, which keeps supply engaged and improves listing quality over time without Viator manually auditing every operator.

The competitive landscape

GetYourGuide is Viator's closest global competitor, founded in Zurich in 2009 and now headquartered in Berlin, backed by more than $1 billion in funding (CNBC). It differentiates on a cleaner mobile experience, faster instant-confirmation rates, and heavier investment in original destination content and curated "must-do" collections. Where it falls short: its supply density is thinner than Viator's in secondary and tertiary destinations, since it has historically focused resources on top-tier cities. That gap is an opening for platforms willing to go deep on smaller or emerging destinations that GetYourGuide hasn't prioritized.

Klook dominates the Asia-Pacific experience market, with strong positions in Japan, Korea, Singapore, and Hong Kong. It built local payment method support (Alipay, GrabPay, and similar) and transportation-adjacent bookings (airport transfers, eSIMs, rail passes) years before Western competitors treated Asia as a priority market. It falls short outside its home region, where brand recognition and supply density both drop sharply. That leaves room for regional specialists in Latin America, the Middle East, or Africa to replicate Klook's localized playbook where neither Klook nor Viator has invested heavily.

Airbnb Experiences takes a fundamentally different supply model: individual hosts running small-group, personality-driven activities (a cooking class in someone's apartment, a photography walk led by a local) rather than licensed tour operators running scaled itineraries. This produces more distinctive, harder-to-commoditize listings, but it struggles with consistency, liability, and availability at scale, and Airbnb has scaled the category back and relaunched it multiple times as a result. The opening it creates: a marketplace that combines host-led intimacy with the operational reliability (insurance, backup guides, cancellation guarantees) that Airbnb has struggled to standardize.

TripAdvisor Experiences runs alongside Viator under the same parent company but as a distinct brand and checkout flow, leaning on TripAdvisor's review volume and SEO authority to cross-sell activities to people already researching a trip. The dual-brand structure occasionally confuses travelers about which site to book through, and the review-first model means it competes on content marketing more than on operator relationships. This creates room for a platform that wins on operator trust and support rather than content scale alone.

Tiqets focuses narrowly on museums, attractions, and skip-the-line tickets rather than the full spectrum of tours and activities. Its narrower focus lets it build deeper integrations with venue ticketing systems and faster mobile entry (direct QR scanning at turnstiles), a level of polish that harder-to-standardize multi-day tour products don't need. The lesson for new entrants: a tightly scoped category can out-execute a generalist competitor on the specific transactions that category involves.

How to build a marketplace like Viator

1. Define your niche within Viator's category

You are not building a second Viator. Viator already has the operator network, review volume, and SEO authority that took a decade to build, and matching it directly is not a realistic goal for a new entrant. What is realistic is picking a specific wedge Viator serves poorly: a single destination or region where Viator's supply is thin, an activity vertical (van life road trips, culinary tours, accessible travel, sober travel experiences) that mainstream platforms treat as an afterthought, or a buyer segment (corporate offsites, multigenerational family trips, solo female travelers) with needs generic search filters don't capture. Every successful experience marketplace that has carved out real share started with a specific answer to "why would someone use this instead of Viator," not a vague ambition to be more comprehensive.

2. Validate demand with real conversations

Talk to both sides before writing a line of code or configuring a single listing. On the traveler side, find out where people currently go to book your target activity type, what frustrates them about it, and whether they'd pay for a better alternative. On the supply side, talk to operators directly: what percentage of their bookings come through Viator or GetYourGuide today, what commission they're paying, and what would make them list somewhere else. Operators who feel squeezed by high commissions or poor support from incumbents are your best early adopters, and their answers will tell you whether your wedge is a business or a hobby.

3. Choose your development approach

Vibe coding from scratch. AI tools like Cursor, Lovable, and Bolt can produce a working Viator-style prototype quickly: a searchable listing grid, a booking form, a basic calendar. For pressure-testing a concept or demoing to early operators, that's genuinely useful. For launching a platform that handles real money between travelers and operators, it's probably not sufficient. What vibe-coded outputs reliably don't produce is the infrastructure underneath: payment escrow, dispute resolution, fraud detection, and compliance. A documented Sharetribe experiment ran 60+ hours to reach demo quality but revealed a critical checkout exploit that would have allowed price manipulation via direct API call. Bringing the output to production standard requires significant time, testing, and a clear understanding of how the different components of a web application fit together. A useful prototyping tool, not a cost-effective path to launch.

Custom development from scratch. Hiring developers (who will likely use AI heavily themselves) gives you full control over the product. An experience marketplace with reviews, operator payouts, cancellation policies, and identity verification for guides sits squarely in the production-grade tier: $80,000-$200,000 over 16-28 weeks (Codica, RaftLabs). What pushes it there is real-time availability syncing across operators, escrow-style payment holds until after the experience, and dispute handling for no-shows or weather cancellations. The low end of that range assumes an offshore team; a US or Western European team will land you closer to the top. Custom development makes sense once you have requirements (a proprietary matching algorithm, deep integration with a specific booking system operators already use) that no existing platform can meet.

Building on a marketplace operating system like Sharetribe. You start at roughly 90% done on the standard marketplace foundation: payments, user accounts, listing management, messaging, transaction flows, fraud detection, and compliance. Your time and budget go toward the features that make your experience marketplace distinct, not toward rebuilding a checkout flow. Three paths within this approach:

• No-code builder. Configure availability calendars, booking flows, cancellation policies, and commission rates from the Sharetribe Console without writing code. Enough to launch a live, bookable experience marketplace in a specific niche within weeks.
• AI-assisted development. Connect Claude Code, Cursor, or Codex to Sharetribe's open APIs and open-source template to build category-specific features: a fitness level filter for adventure tours, a group-size calculator for private guides, or a weather-dependent rescheduling flow. Because Sharetribe handles the payment infrastructure, AI-assisted development on top of it carries much lower risk than building from scratch.
• Custom code. Build directly on the developer platform for deeper integrations (operator booking system syncs, custom mobile apps), or hire from Sharetribe's Expert Marketplace.

Most founders start with the no-code builder, launch, and then add features via AI or a developer once they know what their travelers and operators actually need.

4. Solve the cold start problem

Experience marketplaces face a specific version of the chicken-and-egg problem: travelers won't book on a platform with thin listings in their destination, and operators won't invest time listing on a platform with no traffic. Viator solved this in the early 2000s by aggregating inventory from operators who had almost no other online distribution channel at all, meaning the bar for "better than nothing" was very low. That bar is much higher today.

Concrete tactics that work for new entrants: go supply-first in one tightly defined geography (a single city, a single region) and personally onboard 20-30 quality operators before opening to travelers, rather than trying to seed a global catalog. Seed a niche community first, for example partnering with a Facebook group or newsletter audience that already cares about your activity type, so your first travelers arrive with built-in trust in the source. Or manually match early bookings yourself, taking requests by phone or email and personally connecting travelers with operators, to learn the operational details before automating them. Launching small and tight, with real supply density in one narrow area, consistently beats launching broad and thin across many destinations with only a handful of listings each.

5. Build your MVP around booking mechanics, not polish

At launch, prioritize the mechanics that make a booking trustworthy: accurate availability, clear cancellation terms, and reliable payment collection. Skip advanced features like dynamic pricing, AI-powered recommendations, or a native mobile app until you have booking volume that justifies them. A clean, honest booking flow on a handful of well-vetted listings will outperform a feature-rich platform with unreliable availability every time.

6. Recruit and support your first operators

Direct outreach beats cold email in this category. Visit operators in person if you can, attend regional tourism trade shows, and offer concrete early-adopter terms: a reduced commission for the first six months, free professional photography for their listings, or hands-on help setting up their calendar. Many small tour operators have limited experience with online distribution, so being genuinely helpful during onboarding, not just collecting a listing, is a real differentiator against platforms that treat operators as a self-serve afterthought.

7. Launch and gather feedback fast

Market to a narrow traveler segment first, through content (destination guides, activity round-ups) and communities where your niche traveler already spends time, rather than broad paid acquisition. Treat your first 100 bookings as a research project: call travelers after their experience, ask operators what friction they hit, and fix the workflow issues that show up repeatedly before scaling spend.

8. Expand deliberately

Once booking volume and operator retention are healthy in your first market, expand to an adjacent geography or activity category, not both at once. Each new market brings new payment preferences, language needs, and operator relationships to build from scratch, so expanding one variable at a time keeps the operational load manageable.

Do you need to build everything Viator has?

No. Viator's mobile apps, dynamic pricing engine, recommendation algorithms, and global operator support infrastructure are the product of more than two decades and, since 2014, TripAdvisor's balance sheet. None of that is required to launch a useful, bookable marketplace in a specific niche. What's essential at launch is a working search-to-booking flow, reliable availability, secure payment collection, and basic review functionality. Everything else (loyalty programs, AI trip planning, white-label APIs) is expansion, not foundation.

The temptation to "just vibe-code a clone" deserves a direct answer. AI tools are genuinely good at producing a demo-quality booking site quickly, and that's useful for testing whether operators and travelers respond to your niche. But a demo is not a business: the same Sharetribe experiment that produced an impressive-looking prototype in 60 hours also found a checkout vulnerability that would have let any user manipulate transaction prices directly through the API. Starting on a marketplace operating system is actually faster than vibe-coding a real launch, because the payment infrastructure, user accounts, and compliance groundwork are already built and tested. Your AI tokens go toward the booking rules and operator features that make your platform distinct, not toward rebuilding a secure checkout from zero.

Trust and safety for a Viator-type marketplace

Experience marketplaces carry trust risks that product marketplaces don't. Travelers pay in advance for something they can't inspect beforehand, so payment protection and honest listing information matter more than in most e-commerce categories. Physical safety is also a real concern: activities involve guides, equipment, and sometimes physical risk (hiking, water sports, adventure activities), so operator vetting and insurance verification carry real liability weight, not just reputational weight.

Standard verification in this space includes requiring business licenses, liability insurance documentation, and, for higher-risk activities, safety certifications before an operator can list. Two-way review systems, where operators can also rate difficult travelers, build accountability on both sides rather than assuming travelers are always right. Clear, prominently displayed cancellation and weather policies prevent the disputes that otherwise flood customer support.

Sharetribe provides payment escrow through Stripe Connect (funds held until a defined release point, not paid to operators before the experience happens), structured transaction flows that enforce your cancellation and refund rules automatically, and user accounts with optional identity verification steps. What founders need to add on top: the specific vetting criteria for their category (insurance thresholds, certification requirements) and the manual review process for flagging or removing operators who don't meet them. Sharetribe gives you the rails; you define the rules that fit your niche.

Running a marketplace like Viator

Day-to-day operations for a focused experience marketplace are lighter than they look from the outside. You'll spend time on operator support (calendar updates, listing quality, payout questions), customer service for booking issues, and ongoing quality control through reviews and periodic operator check-ins. What you won't need to replicate early on is Viator's scale infrastructure: enterprise fraud detection systems, a 24/7 multilingual call center, or a dedicated business intelligence team. Those get built as volume demands them, not before.

Sharetribe handles the technical operations automatically: payment processing and payouts, hosting and uptime, security patching, and the underlying transaction logic that enforces your booking and cancellation rules. That leaves your team free to focus on the parts that actually differentiate a niche experience marketplace: operator relationships, listing quality, and customer trust.

Development costs and timeline

Three realistic scenarios:

Vibe coding from scratch: Free or very cheap to start, and a working Viator-style prototype is buildable in days with AI tools. What you can't get from here is a production-ready platform: secure payment escrow, real-time availability sync across multiple operators, dispute resolution workflows, and identity verification all require work that AI coding tools don't shortcut. A documented Sharetribe experiment logged 60+ hours to reach demo quality and found critical payment vulnerabilities in the process. A useful proof-of-concept tool, not a cost-effective path to a live business.

Custom development from scratch: Cost depends on complexity tier. A basic tour-listing MVP with simple booking and messaging sits at $30,000-$80,000 over 8-20 weeks. A production-grade build with reviews, operator identity verification, payment escrow, and dispute flows (what a real Viator competitor needs) runs $80,000-$200,000 over 16-28 weeks (Codica, RaftLabs). Real-time multi-operator availability syncing and native mobile apps push the higher end of that range or beyond it. The low end assumes an offshore team; US or Western European rates push toward the top. Ongoing maintenance typically runs 15-25% of build cost per year on top. Makes sense only when your operator integrations or booking logic can't be handled by an existing platform.

Building on Sharetribe: Before you launch, the Sharetribe Build plan costs just $39/month. To open to real users, you need the Live plan, which costs $199/month billed yearly ($259/month billed monthly). Both plans include 1 million usage credits per month. Sharetribe covers hosting, payment infrastructure through Stripe Connect, listing and search functionality, messaging, and the transaction engine that handles bookings, cancellations, and payouts, the exact foundation a Viator-style marketplace needs. Most founders reach a live, bookable MVP in weeks rather than months. Category-specific features (fitness-level filters, group booking calculators, weather-based rescheduling) get added via AI tools or a developer afterward, scoped narrowly because the core transaction engine is already built.

Why Sharetribe for building a marketplace like Viator

Sharetribe's built-in availability calendars and booking transaction flows map directly onto what an experience marketplace needs: date-based inventory, instant or request-to-book confirmation logic, and configurable cancellation windows. Its Stripe Connect integration handles the commission-based payment splits that mirror Viator's own revenue model, collecting a platform fee automatically while paying operators on your defined schedule. Because the underlying data schema is customizable, you can add category-specific attributes (activity duration, fitness level, group size, meeting point coordinates) without touching core infrastructure. And because the whole platform is built on open APIs, an AI coding assistant can extend it with the features that make your niche marketplace distinct, while the payment and compliance foundation underneath stays solid.

Frequently asked questions

How much does it cost to build a website like Viator?

It depends on your approach. A custom-built production-grade platform with reviews, escrow, and dispute handling runs $80,000-$200,000 and takes 16-28 weeks (Codica). Building on Sharetribe costs just $39/month on the Build plan after a 14-day free trial (the Live plan for running your marketplace is $199/month billed yearly), with most founders reaching a live MVP in a few weeks rather than months.

How does Viator make money?

Viator earns commissions from tour and activity operators on each completed booking, generally reported in the 20-30% range depending on volume and category (All my tours). It supplements this with paid placement for operators, affiliate and white-label partnerships, and cross-selling from parent company TripAdvisor's traffic.

What is the biggest competitor to Viator?

GetYourGuide is Viator's closest global competitor, known for a stronger mobile experience and heavier investment in original destination content. Klook leads in Asia-Pacific markets, and Airbnb Experiences offers a smaller-scale, host-led alternative for more intimate activities.

Can I build a Viator-style marketplace without coding?

Yes. Sharetribe's no-code builder lets you configure listings, availability calendars, booking flows, and commission structures from the Console, enough to launch a live bookable marketplace without writing code. Custom features can be added later through AI-assisted development or a developer as your platform grows.

How do you get tour operators to join a new marketplace?

Start with direct, in-person outreach rather than mass email, focusing on operators who are underserved by existing platforms or struggling with seasonal demand. Offer early-adopter incentives like reduced commissions, free listing photography, or hands-on onboarding support to build initial supply density in one geography before expanding.

What features does a tour and activity marketplace need at launch?

The essentials are real-time availability, location-based search, a secure and flexible payment flow, review functionality, and clear cancellation policies. Advanced features like dynamic pricing, AI recommendations, or native mobile apps can wait until you have booking volume that justifies the investment.
