Read Story

How 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.

Test that users can submit the contact form
with a valid email and see a success message

test_contact_form.pyAI GENERATED

def test_submit_with_valid_email(page):    page.fill("input[name=email]", "[email protected]")    page.click("button[type=submit]")    assert page.locator(".success").is_visible()

Deploy anywhere
Ship to Reflex Cloud or your own infrastructure.

“Reflex definitely saved us from needing to hire a frontend engineer and sped us up by 4x relative to learning React.”

Misha van Beek, Co-founder, Bayesline

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.

Integrations

Connect to your systems

Your databases, your APIs, your internal libraries — not just pre-built SaaS integrations. Any Python package works.

Pre-built integrations, pre-vetted

The agent uses tested abstractions for every integration. Same implementation, every time — so what works on your laptop works in production, and what works for one teammate works for the next.

Explore integrations

Or any Python package

Pre-built isn't the limit — Reflex is Python, so the agent can use anything on PyPI or your private registry. Lovable and v0 can't say that.

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. Builders create within them. Viewer seats let stakeholders review and interact with apps — no deploy, no separate staging environment, no extra license.

Code you can trust

Production code, not AI slop

Every app outputs clean, readable Python backed by git.

Every change, backed by git

Every AI change, every human change — committed to a real git branch with a message and an author. Full history, branches, rollback to any version. Audit-ready out of the box.

Code your team would actually approve

Reflex apps output idiomatic Python with type hints, docstrings, and the patterns your senior devs would use. Built on the framework Amazon, NASA, and Dell ship on. Apache 2.0 — you own the code.

App Management

Choose your path to production

One click to Reflex Cloud—SSL, CDN, and scaling included. Bring your own AWS, GCP, or Azure with our deployment scripts, or run on-prem. For enterprise, the AI builder itself runs on your infrastructure.
