Know what works before you ship.
Rehearsal explores your app, writes the tests and runs them on web, mobile and desktop, locally and on every pull request. It keeps them working as your app changes, so you do almost nothing.
Be first in. Early members get perks when Rehearsal opens.
Terminal, coding agents, GitHub and Vercel.

Message Re:agent
Start with the flow that matters.
Re:agent uses your app the way a person would and turns what it did into a test. Here it checks that an invited member can join a project.
flow.spec.ts
await test.step('Sign in as the owner', async () => { await owner.page.getByLabel('Password') .fill(owner.password()); await owner.page .getByRole('button', { name: 'Sign in' }).click();});await test.step('Open the invitation as the member', async () => { const email = await member.latestEmail(); await member.page.goto(email.links[0]);});Verify
Checked again from a clean start.
Rehearsal reruns the new test before marking it ready.

Checking it in a fresh browser
QA subagents explore your app.
Say what to check, or nothing at all. Subagents open your app in real browsers and report the bugs they find.
- Each subagent takes one area of your app.
- A subagent checks each case against what your app should do.
- Each bug comes with the step it happened on and a recording.
Test every side of your app.
When a flow involves two people, each gets a browser of their own. Follow an invitation from the person sending it to the person accepting it.
More than one person
Up to four people in one flow, each signed in with their own test account.

Test while you build.
Connect the app running on your machine and run your saved tests against it. Rehearsal reaches it through a connection you keep open in your terminal.
npm install -g @rehearsal-labs/clirehearsal
Built on Retest.
Retest is the test library Rehearsal runs your tests on. You can read its code, run it yourself and use it without Rehearsal.
- A flow written once runs on web, mobile and desktop.
- It runs in your terminal and in your CI.
- Every test Rehearsal writes runs on Retest.
Works with your coding agent.
Your agent can run the saved tests, read where one stopped, fix the app and run them again. Every command answers in JSON with the next step.
- Gemini CLI
- OpenCode
- Claude Code
- Codex
- Cursor
Bring your tests into every release.
Connect a repository and choose which tests run on pull requests and deployments. Rehearsal tests the preview and posts the result on the commit.

See what happened.
Open the run, follow its steps and watch the recording. A failed check names the step, what it expected and what the page showed.

Failed at step 12. It expected the page to show Parcel. The page showed No projects yet.
Run again after the fix. 12 of 12 steps passed in 39s.
A run that stops because of Rehearsal is marked could not run. It never counts as a failure and is never charged.
