Hi πŸ‘‹

We are Robbe and Ruwan, two software engineers from πŸ‡§πŸ‡ͺ Belgium who maintain Connexion, almost entirely in our free time.

Connexion is a modern Python web framework that makes spec-first and api-first development easy. You describe your API in an OpenAPI (or swagger) specification with as much detail as you want and Connexion will guarantee that it works as you specified 🀯


We took over Connexion 2 years ago.

  • The first year we worked through the backlog of 400+ open issues and learned the ins and outs of the code base while releasing new versions regularly again.
  • The second year we mainly worked towards Connexion 3.0, a redesign of Connexion as an ASGI middleware stack, which brings new modern features to Connexion (such as asynchronous support), and solves some of the longest-standing issues.

Connexion 3 is now generally available. We're excited for you to try it out! 😍


We spent hundreds of hours on improving Connexion already. By sponsoring us, you help us buy time to spend hundreds of hours more to both maintain the current functionality of Connexion and implement new large features like:

  • OpenAPI 3.1 support
  • Parsing incoming requests into Python objects
  • Support for additional authentication schemes
  • And much more...

Any feature you're missing? Please tell us about it by opening an issue!
