Every change, backed by git
Review changes from the agent and your teammates in version history. Use branches and earlier versions to manage the app as it evolves.
Build with AI. Ship with confidence.
The AI app builder with built-in testing and production Python code you own.

Read all storiesHow it works
Describe, build, test, and ship it
From an idea to a tested, production-ready Python app in four steps.
Describe what you want
Start with a prompt, document, or screenshot.
Watch it come to life
Build your app with AI and see changes live.
Test before you ship
Review AI-generated tests or add your own.
Deploy anywhere
Ship to Reflex Cloud or your own infrastructure. On Enterprise, the builder runs there too.
“If I was able to publish one custom application a month previously, I can publish seven now.”

Testing
AI-assisted testing, built in
AI suggests tests automatically. You review, customize, or add your own.
The agent writes the tests
AI suggests pytest, browser, and UI tests. Review and customize them for your app.
Catch regressions before they ship
Run the full suite on every build and see which changes need attention before release.
Code you can trust
Production code you own
Review the Python, inspect a change, and keep working in your own development workflow.
Python your team can inspect
Inspect and edit the generated application code. Apps use the open-source Reflex framework; the commercial Builder is a separate product.

Connect to your systems
Use your databases, APIs, and internal Python libraries in the apps you build.
01
Pre-built and tested
Start with existing integration patterns, then configure credentials and permissions for the systems your team uses.
02
Or any Python package
Use Python packages and your private libraries when an application needs a custom connection.
Collaboration
Bring your whole team in
Technical and non-technical, working on the same codebase.
One codebase, two editors
Your engineer ships with Claude Code and MCP from a terminal. Your PM builds in the visual web builder. Same project, same branches, same test suite — nobody re-implements anything.
Roles built for real teams
Admins set integrations and guardrails, and builders create within them. On Enterprise, viewer seats let stakeholders review and use apps without builder access.
