How to build a website like Klook (2026 guide)

What is Klook and how does it work?

Klook is a two-sided marketplace that connects travelers with tours, attractions, and local experiences, primarily across Asia-Pacific. Founded in Hong Kong in 2014 by Ernest Lee, Eric Gnock Fah, and Bernie Xiong, the platform lets suppliers (attractions, tour operators, transport providers, restaurants) list bookable inventory, while travelers search, compare, and book instantly through Klook's app or website. The company has raised over $1 billion from investors including SoftBank Vision Fund, HongShan (formerly Sequoia Capital China), and Matrix Partners, and publicly filed for a US IPO on the New York Stock Exchange in November 2025 (Bloomberg).

Klook lists more than 500,000 activities across over 2,700 destinations, covering everything from theme park tickets and airport transfers to cooking classes and multi-day tours (Klook). The transaction flow is straightforward from the traveler's side: search a destination, pick an activity and time slot, pay online, and receive a mobile voucher or QR code for entry. Behind that simplicity sits a supplier dashboard that manages availability calendars, pricing tiers, and payout schedules, which is the part most new entrants underestimate when they try to replicate the model.

How Klook makes money

Klook's core revenue comes from commission on bookings, typically ranging from 10% to 25% of the transaction value depending on the activity category, supplier volume, and negotiated terms (Klook S-1 breakdown). High-volume suppliers, such as major theme parks, often negotiate lower commission rates in exchange for guaranteed distribution, while smaller or niche operators pay closer to the top of that range.

Beyond commission, Klook generates revenue through supplier advertising, where operators pay for featured placement in search results or curated collections, similar to sponsored listings on an e-commerce marketplace. The platform also sells ancillary travel products directly, including travel insurance, mobile SIM cards and eSIMs, and airport lounge access, which carry their own margins separate from the core commission model.

A smaller but growing revenue stream comes from Klook's B2B business, where the company licenses its inventory and booking technology to other travel platforms, airlines, and banks that want to offer activities booking to their own customers without building it themselves. This white-label distribution model extends Klook's reach without requiring direct consumer acquisition spend.

What makes Klook work: key features

Real-time availability and capacity management. Activities have hard capacity limits tied to specific time slots, unlike products with unlimited inventory. Klook's system tracks remaining spots per session and closes bookings the instant capacity is reached, which prevents the overbooking that destroys trust in a booking marketplace.

Instant confirmation and mobile vouchers. Most Klook bookings confirm immediately with a QR code voucher, eliminating printed tickets or waiting for supplier email replies. This matters because activity bookings are frequently made same-day or next-day, unlike flights or hotels booked months out.

Location-based discovery. Klook's search understands destinations, neighborhoods, and proximity to landmarks or hotels, letting travelers find "things to do near me" rather than only searching by activity type. This geographic layer is core to how spontaneous, in-destination bookings happen.

Flexible, localized payments. Klook supports dozens of local payment methods across its markets, from Alipay and WeChat Pay in China to GrabPay in Southeast Asia and credit cards elsewhere, alongside multi-currency pricing. This localization is a major reason Klook outperforms Western competitors in Asian markets.

Curated collections and editorial content. Rather than presenting flat search results, Klook packages activities into themed collections ("Best Tokyo Day Trips," "Hidden Gems in Bali") that help undecided travelers discover activities they didn't know to search for.

Supplier self-service dashboard. Operators manage their own calendars, pricing, and promotions without needing account manager intervention for routine changes, which lets Klook scale supplier relationships without proportional headcount growth.

Review and rating system tied to verified bookings. Reviews are only collected from confirmed bookers, which keeps the feedback loop credible and helps travelers judge experience quality before committing.

The competitive landscape

Viator dominates in Western markets through its ownership by Tripadvisor, inheriting a massive review database and organic traffic. It covers guided tours and excursions comprehensively across Europe and North America with high production-value listings. Its weakness is limited depth in Asia-Pacific and a heavier emphasis on traditional group tours over spontaneous, local, or last-minute activities, which leaves room for platforms built around mobile-first, in-destination booking.

GetYourGuide competes on curation and premium positioning, working directly with suppliers to build exclusive experiences and maintaining strict editorial and quality standards. Its Berlin roots give it strong European coverage, but that curation means fewer total listings per destination than aggregator models, and pricing tends to run higher. A new entrant can compete by covering the long tail of budget or niche activities GetYourGuide screens out.

Airbnb Experiences takes a peer-to-peer approach, letting locals host activities rather than working through commercial operators, which produces more distinctive, personal offerings. Quality and availability are inconsistent by design, since hosts are individuals rather than professional operators, and coverage is thin outside major cities. This creates an opening for platforms that combine local, authentic-feeling experiences with the reliability of professional supplier vetting.

KKday, Tiqets, and Pelago represent regional specialists that out-execute global players in specific markets. KKday has deep Taiwan and broader Asia coverage, Tiqets focuses on skip-the-line attraction tickets in Europe, and Pelago (backed by Singapore Airlines) leans into premium, curated Southeast Asian experiences. These platforms typically have smaller technology budgets than Klook, which is exactly where a well-built, modern platform can win on user experience even with less inventory.

Google and direct-to-supplier booking represent the biggest adjacent threat, not a named platform but a behavior shift. Google's "Things to do" panels increasingly let travelers book directly with Reserve with Google integrations, and many attractions now push their own direct booking sites hard to avoid commission. Any new marketplace needs a value proposition beyond aggregation alone, whether that's better local curation, bundling, or trust signals suppliers can't replicate on their own site.

How to build a marketplace like Klook

1. Define your niche within Klook's category

Klook's category is enormous: hundreds of thousands of activities across dozens of countries. Competing broadly against that is not realistic for a new entrant. Instead, pick a specific wedge: a single city or region, a specific activity type (food tours, adventure sports, cultural workshops), or a specific traveler segment (solo female travelers, accessible travel, luxury small-group experiences). Klook itself started narrowly, focused on mobile-savvy travelers in Hong Kong, before expanding across Asia-Pacific over several years.

2. Validate demand and supplier willingness before building

Talk to both sides before writing a line of code or configuring a platform. Interview travelers in your target niche about how they currently book activities, where the friction is, and whether they'd try a new platform. Interview potential suppliers about their current customer acquisition costs, their appetite for another booking channel, and what would make onboarding easy enough to bother with. Many marketplace founders skip this and discover, post-launch, that the pain point they assumed existed wasn't strong enough to shift behavior.

3. Choose your development approach

Vibe coding from scratch. AI tools like Cursor, Lovable, and Bolt can produce a working Klook-style prototype quickly, useful for pressure-testing a concept or showing early suppliers what you have in mind. For launching a platform that takes real payments from strangers, they're probably not sufficient on their own. 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 a direct API call. Bringing that output to production standard takes significant additional time and a clear understanding of how the pieces of a web application fit together. Treat it as a prototyping tool, not a launch path.

Custom development from scratch. Hiring developers, who will likely use AI heavily themselves, gives you full control over architecture and features. An activities marketplace with time-slot booking, location search, and multi-party payments sits mostly in Tier 2 territory: a production-grade build with reviews, supplier verification, and dispute handling runs $80,000–$200,000 over 16–28 weeks (Codica, RaftLabs). A narrower single-city MVP without heavy verification can land at the Tier 1 range, $30,000–$80,000 over 8–20 weeks. The low end of each range assumes offshore teams billing $15–40/hour; US or Western European teams push toward the top or beyond. This route makes sense when you need integrations or a business model no existing platform can support.

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 what makes your activities marketplace distinct.

• No-code builder. Configure time-slot bookings, location-based search, multi-currency pricing, and commission rates from the Console, no code required. This gets most founders to a live, bookable activities marketplace in weeks.
• AI-assisted development. Connect Claude Code, Cursor, or Codex to Sharetribe's open APIs and open-source template to build Klook-specific features, like a curated collections page, a supplier analytics dashboard, or custom cancellation logic. Because Sharetribe already handles payment infrastructure, this carries far less risk than building payment flows from scratch with AI.
• Custom code. Build directly on the developer platform for deeper integrations (local payment methods, third-party inventory feeds), or hire a specialist from Sharetribe's Expert Marketplace.

Most founders start with the no-code builder, validate that suppliers and travelers actually use the platform, then layer in AI-assisted or custom features as real needs surface.

4. Solve the cold start problem

Activities marketplaces face a sharp version of the chicken-and-egg problem: travelers won't browse a platform with thin inventory, and suppliers won't bother listing on a platform with no traffic. Klook solved this early by focusing obsessively on Hong Kong and a handful of headline attractions (theme parks, popular tours) that gave the platform credibility, then expanded city by city using the same playbook.

Three tactics work for new entrants. First, go supply-first in one city or region: personally recruit 20-30 high-quality suppliers before opening bookings publicly, so early travelers see a genuinely useful selection rather than a thin catalog. Second, anchor on one or two flagship suppliers, a well-known attraction or standout local operator, whose credibility pulls in travelers and signals quality to other potential suppliers. Third, consider manual matching in the earliest days: personally connecting the first few travelers with suppliers by phone or message, even if it doesn't scale, teaches you what an automated booking flow actually needs to handle. Launching narrow and dense in one geography beats launching broad and empty across ten cities.

5. Build trust and safety into the booking flow from day one

Travelers are booking unfamiliar activities in unfamiliar places, often with no ability to inspect what they're paying for in advance. Clear cancellation policies, verified supplier credentials, and responsive customer service need to exist before your first real booking, not after your first dispute.

6. Launch with a tight early-adopter group

Recruit a small group of engaged travelers, through travel communities, local Facebook groups, or direct outreach, rather than attempting a broad marketing launch. Offer incentives for early bookings and treat every one of them as a source of feedback on where the booking flow breaks down.

7. Iterate on real booking data, not assumptions

Track conversion rate from search to booking, completion rate at checkout, and supplier response time to booking requests. These fundamentals matter more in the first few months than adding new destinations or features.

Do you need to build everything Klook has?

No. Klook took over a decade and hundreds of millions in funding to build multi-language support across a dozen languages, real-time inventory integrations with thousands of suppliers, a mobile app with offline access, and a B2B distribution business. None of that is required to launch. What's required at launch is a working booking flow: search, listing detail, availability, payment, and confirmation, done reliably for one geography and a focused set of suppliers.

The instinct to "just vibe-code a clone" is understandable given how capable AI tools have become, but it misunderstands where the actual work sits. The hard part of an activities marketplace was never the search bar or the listing page, both of which AI tools generate quickly. It's the multi-party payment splitting, the availability logic that prevents double-booking, the fraud checks, and the compliance requirements around handling customer money. Starting on Sharetribe means that layer already exists, so whether you use the no-code builder or connect an AI coding tool to Sharetribe's APIs, your effort and token spend go toward the collections page, the supplier dashboard tweak, or the local payment integration that actually differentiates your platform, not toward reinventing checkout security.

Trust and safety for a Klook-type marketplace

The core trust risks in an activities marketplace are supplier reliability (does the tour actually run as described), payment disputes (refunds for cancellations, weather, or no-shows), and physical safety for activities involving any risk (adventure sports, water activities, transport). Unlike a marketplace for physical goods, there's often no way for a buyer to inspect what they're purchasing before the moment they show up.

Standard verification in this space includes business license checks for suppliers, insurance requirements for higher-risk activities, and a clear, published cancellation and refund policy that travelers can read before booking. Review systems tied to verified bookings, rather than open reviews, help keep feedback credible.

Sharetribe provides payment escrow through Stripe Connect (funds move to the supplier only after the transaction completes per your rules), configurable transaction flows that can require supplier confirmation before charging a customer, and user accounts with optional identity verification. What founders need to add themselves: category-specific supplier vetting (license checks, insurance verification), a written dispute resolution policy for weather cancellations or no-shows, and, for higher-risk activity categories, liability waiver collection built into the booking flow.

Running a marketplace like Klook

Day-to-day operations for an activities marketplace center on supplier support (helping operators manage calendars and pricing), customer service (handling cancellations, refunds, and day-of issues), and content or marketing (surfacing the right activities to the right travelers). At Klook's scale, this means dedicated country teams, 24/7 multilingual support, and a large business development organization managing thousands of supplier relationships, none of which a new entrant needs to replicate on day one.

Sharetribe automatically handles the transactional plumbing: payment splitting between platform and supplier, booking confirmations, automated emails and notifications, and the underlying availability calendar logic. That leaves your early team free to focus on the things that don't automate well, recruiting good suppliers, resolving the occasional dispute personally, and figuring out which activities and destinations actually convert.

Development costs and timeline

Three realistic scenarios:

Vibe coding from scratch: Free or very cheap to start, and a working Klook-style prototype is buildable in a weekend with AI tools. What you can't get from here is a production-ready platform: multi-party payment splitting with proper escrow, availability logic that actually prevents double-booking under concurrent traffic, fraud detection, and compliance with payment regulations all require work that AI coding tools don't shortcut. A documented Sharetribe experiment logged 60+ hours to reach demo quality and still turned up a critical checkout exploit. Treat it as a proof-of-concept tool, not a path to a live business handling customer money.

Custom development from scratch: A single-city activities marketplace MVP with basic booking and payments sits in Tier 1, $30,000–$80,000 over 8–20 weeks. Add reviews, supplier identity verification, escrow-style payment holds, and a dispute flow, standard for a multi-destination activities marketplace, and you're in Tier 2, $80,000–$200,000 over 16–28 weeks (Codica, RaftLabs). The low end assumes offshore development teams; US or Western European teams push toward the top of the range or beyond. Ongoing maintenance typically runs 15-25% of the original build cost per year on top of hosting. This route makes sense if you need deep local payment or inventory integrations no existing platform supports.

Building on Sharetribe: Subscription pricing starts at $99/month on the Lite plan, $199/month on Pro, and $299/month on Extend (all billed yearly). This covers the transaction engine, payment processing through Stripe Connect, availability calendars, user accounts, messaging, and search, the foundation that otherwise costs tens of thousands of dollars to build. Most founders reach a live, bookable MVP in weeks. Features specific to your niche, a supplier analytics view, a custom collections page, a local payment method, get added later via the no-code builder, AI-assisted development, or a developer, scoped narrowly because the core transaction engine already works.

Why Sharetribe for building a marketplace like Klook

Sharetribe's booking transaction type handles time-slot availability and capacity limits natively, the exact problem that makes activities marketplaces harder to build than simple product marketplaces. Payments run through Stripe Connect, splitting commission and supplier payout automatically on every booking, which is the multi-party payment logic that takes custom-built platforms months to get right. Location-based search comes built in, letting travelers filter by destination or proximity without you needing to integrate mapping APIs from scratch. Review functionality ties ratings to completed bookings, and the whole platform is mobile-responsive by default, matching how most activity bookings actually happen: on a phone, at or near the destination, often same-day.

Frequently asked questions

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

It depends on your build path. A vibe-coded prototype costs little but isn't production-ready. Custom development runs $80,000-$200,000 for a production-grade activities marketplace with reviews and dispute handling (Codica). Building on Sharetribe starts at $99/month and gets you a live MVP in weeks rather than months.

How does Klook make money?

Klook earns commission of roughly 15-30% on each booking, plus advertising fees from suppliers seeking featured placement and revenue from ancillary products like travel insurance and eSIMs (Bókun). It also licenses inventory and booking technology to other travel businesses through a B2B arm. Commission rates vary by supplier volume and negotiating power.

What's the difference between Klook and Viator?

Klook built its business around mobile-first, last-minute bookings in Asia-Pacific, while Viator, owned by Tripadvisor, focuses on guided tours in Western markets with a large review database behind it. Klook tends to offer more instant confirmation and same-day booking options. Viator has deeper coverage in Europe and North America.

Can I build a Klook competitor without coding?

Yes. Sharetribe's no-code builder lets you configure listings, time-slot booking, location search, and commission-based payments without writing code, and most founders reach a live marketplace this way. You can add AI-assisted or custom development later for features specific to your niche. This is generally faster and lower-risk than custom development from scratch.

How do activities marketplaces prevent overbooking?

They use real-time availability tracking tied to specific time slots and capacity limits, so a booking is only confirmed if a spot is actually open at that moment. Sharetribe's booking transaction type handles this natively, updating availability the instant a booking is made. Building this logic reliably from scratch, especially under concurrent traffic, is one of the harder technical problems in this category.

What niche should I pick if Klook already covers my city?

Klook's broad coverage often comes at the expense of depth in specific activity types or traveler segments, like accessible travel, solo female travelers, hyper-local food experiences, or niche adventure sports. Look for gaps where suppliers feel underserved by Klook's commission structure or generic presentation. A tightly curated, better-served niche beats trying to out-cover a platform with a decade-long head start.
