📣 New in Chromatic: Quarantine for flaky tests
You can now quarantine the flaky diffs that slip past Chromatic’s automatic filter. Quarantine the test from its build or test page to get your PR moving. 🧵⤵️ (1/5)
ALT Chromatic quarantine for flaky tests
The test doesn’t disappear. Quarantined diffs show up in the build’s Unstable group, alongside tests caught by the automatic flake filter. Expand the group to inspect them. (3/5)

Chromatic keeps capturing snapshots for quarantined tests, but ignores their diffs across builds, branches, and users. So the same flaky diff won’t keep showing up for review. (2/5)

Our new Vitest plugin turns the tests you already have into visual tests.
📖 No Storybook required

ALT How to visually test your components with Vitest & Chromatic
Chromatic for @vitest_dev Browser Mode is live. 🧪📸
Browser Mode runs your component tests in a real browser. Now Chromatic checks how those components look by capturing the rendered UI.
No new screenshot assertions. No second suite to maintain. 🧵 (1/4)
ALT Vitest Visual Regression Testing with Chromatic
Run your tests as usual. Chromatic then:
✔️ Compares snapshots across stable cloud browsers
✔️ Runs every browser and viewport in parallel
✔️ Surfaces visual changes in your PR for team review
✔️ Stores the full rendered UI behind every diff

Flaky tests shouldn't block your build.
Meet Flake filter: Chromatic now auto-detects unstable tests, so you can focus on real changes without getting blocked by flakes. 🧵

Bonus: you can now ignore any test manually too. New story not ready for review? Weird diff after a rebase? Set it aside, come back later.
ALT Ignore flaky tests automatically and manually
Flake Filter is live on every plan, on by default, with no setup required.
