From Flaky to Flawless: Metabase’s Journey.
Move fast without
breaking things.
Meet Replay, the first browser with instant replay. It lets you capture your tests in CI, debug failures with browser DevTools, and find the moment something went wrong.
Before Replay, some test flakes were simply not debuggable: we didn't have the information required for anything better than an educated guess. Now, we always have a perfect reproduction, and our tests have a 99.9% pass rate.
Trusted by top engineering teams
Say goodbye to “works on my machine”.
The worst part of fixing hard-to-reproduce issues is figuring out how to replicate them locally. With Replay you can skip that step and start debugging your app with time travel enhanced browser DevTools as if the test is consistently failing.
Debug with instant console logs.
Add console logs in your code with a single click with messages that “automagically” appear in the Console. You’ll love how fast the feedback loop is.
Fix flaky Cypress + Playwright tests.
Replay’s built in test timeline helps you inspect test step details and jump from test step actions into your application’s React event handlers.
Inspect React components
Bugs can appear at any point in time. Replay’s React panel helps you find the component with first visible issues, inspect its props, and work backwards to the root cause.
View network requests
The majority of E2E test failures are caused by backend issues. Replay’s Network monitor helps you find the bad request and inspect the application state at the time.

Replay gives developers the tools needed to fix the tests that are failing today and keep the suite healthy over time.
Tests Dashboard
Drive test flakes to zero.
Replay’s Tests Dashboard helps your team prioritize the worst performing tests, identify new regressions, and celebrate fixes.
Runs Dashboard
Spot regressions quickly.
Replay’s Test Run Dashboard alerts you to new issues in your test suite so you can see which run introduced the problem and address it quickly.
Testsuites Dashboard
Get actionable insights
Replay's Test Suite dashboard gives you meaningful insights into the health of your test suite
PR Comments
Merge with confidence.
Replay’s PR Comments helps developers see if their change is safe to land. And if there are new failures, jump directly into the replay and see what went wrong.

Replay helps some of the largest companies record their E2E tests at scale and verify the correctness of mission critical software.
IN THE LAB
Dynamic analysis
Replay started off as collaborative Browser DevTools, but is quickly becoming a Dynamic Analysis Engine that automates away the debugging process, finds the bugs for you, and identifies regressions missed by the test.
Fix the root cause. Tired of meaningless test failures? Replay will analyze your passing and failing tests and find the fundamental problems in your application causing all of the test failures.
Catch perf issues. Your application can be 10X slower and your tests will still probably pass. Replay analyzes your recent runs and alerts you to performance issues.
