How developing with Flex works
Build an online marketplace the way they should be built.

Leverage the benefits of headless software
Don't worry about building your own APIs, workers or search indexes, or fret over infrastructure and maintenance. You can focus on creating a unique design and workflow. Get started with one of Flex Templates for Web, or build your own custom user interface with the tech stack of your choice.
Design your own data schema
With Flex Extended Data, you can store any type of structured data on your users, listings, and transactions. Have multiple types of users, let them offer any types of products or services, and make it easy for the users to search and filter based on your custom data schema.
Create complex transaction processes
Flex's transaction engine lets you design a fully unique transaction process. Complete with payments, calendar booking, stock and shipping management, complex pricing logic, reviews, email notifications, and more. Using it feels almost like drawing a flowchart and getting back an API based on your drawing. The transaction process definition is versioned, so you can run multiple processes and process versions at the same time.
Extend indefinitely
Flex Integration API, event architecture and Single Sign-On capability make it easy for you to connect to any third party software or plug in your custom backend. There's no limit to how much you can extend your platform. No matter what feature you need, you can always build that on top of Flex.
