Reflex

Reflex is an open-source, full-stack Python framework that allows you to quickly design and deploy web apps. The job it does: making developers faster with better editors, debuggers and workflows.

It makes the most sense for software teams. Alongside the main category they mention Developer Tools and Open Source. As a small product team themselves (11 to 50 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

Reflex is based in San Francisco, California. Their site is reflex.dev.

Before you commit, look at language support, team features, and privacy of your code. A short pilot with your real data tells you more than any demo.

If you have worked with Reflex, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
