The best Lost Pixel alternatives in 2026

Lost Pixel was one of the better open-source visual regression tools: an OSS core you could self-host, a hosted platform on top, and a clean fit with Storybook and CI. In April 2026 its team joined Figma and started sunsetting the product, so if you were on the hosted platform you now need somewhere to go. This is the honest roundup of the real Lost Pixel alternatives in 2026, plus the one case where you do not need to move at all.

Lost Pixel's own site now leads with a banner: "Lost Pixel is joining Figma. We are sunsetting the product and building what's next." There is no published shutdown date, and the open-source core (@lost-pixel/lost-pixel) is still on GitHub and still runs. So the practical situation is split: the managed platform, with its hosted baselines and review UI, is winding down, while the self-hosted OSS mode keeps working for as long as you maintain it. If you relied on the hosted side, that is the part you are migrating.

• Stay on the open-source core, self-hosted. Keep running lost-pixel in your CI with baselines in your repo or an S3 bucket. Free and unchanged, but you own the maintenance of an archived project and you get no managed review UI, no hosted history, and no vendor fixing bugs.
• Move to a maintained tool. Trade the self-hosting for a hosted platform that is actively developed, with a review workflow, hosted baselines, and support. The rest of this page is that shortlist.

Five tools worth a look if you are leaving Lost Pixel. UI Verify comes first because it is the one I build; every other tool then gets an honest case for when it is the better pick.

Coming from Lost Pixel, the thing you feel first is that there is nothing to author and nothing to self-host. UI Verify replays an archive of the Storybook, Playwright, and Vitest tests you already run, so the same suite becomes your visual suite with no new code. On every pull request it screenshots your UI, an AI judge labels each change a regression or an intended change with a reason, and it holds the PR when it finds a regression so a real one cannot merge behind a green check.

• Nothing to self-host or maintain: a managed platform, in place of an archived OSS project you keep running yourself.
• An AI judge that classifies each change and holds the PR on a regression, so review is decisions, not raw diffs. See the AI judge.
• Agent review over MCP: your coding agent reads the exact per-story diffs and verdicts and accepts the intended baselines from the terminal. See triage with your agent.
• Flake handled for you, not self-hosted: on the Lost Pixel OSS core you owned determinism and baselines yourself, so what you gain is the maintenance you stop doing, a seeded Math.random, inlined fonts, a fetch-once image cache, a hermetic network, and prefers-reduced-motion neutralized at capture time, plus a re-render that auto-ignores flakes. See fix flaky visual tests.
• Chrome, Firefox, and Safari on the free tier, at desktop and mobile widths.

Pricing: a free tier of 10,000 snapshots a month with no credit card, then plans from $89 a month for 30,000 snapshots and $0.004 per snapshot beyond that. Not free the way the OSS core was, but with nothing to self-host or maintain in exchange.

Best for: teams whose UI is increasingly written and reviewed by coding agents, and anyone who wants to stop maintaining their own visual testing infrastructure.

Argos is the closest in spirit to Lost Pixel. It is open-core, it diffs the screenshots your CI captures and uploads rather than rendering them for you, and it keeps baselines and a review UI hosted. If what you valued in Lost Pixel was capturing inside your own pipeline with an OSS foundation, Argos will feel the most familiar.

• Hosted baselines and a PR check over screenshots your pipeline produces.
• SDKs for Storybook, Playwright, Puppeteer, and WebdriverIO.
• Open-source roots with a free tier for small projects.

Best for: teams happy to keep capturing in their own CI who want an open-core hosted diff layer. See the best Argos alternatives.

Lost Pixel was frequently paired with Storybook, and Chromatic is the Storybook team's own visual testing service, so a Storybook-heavy migration lands there most naturally. UI Verify captures Storybook first-class and skips unchanged stories the same way, so what actually sets Chromatic apart is the design-review layer on top: designers sign off changes in a dedicated UI Review, a published Storybook is permalinked across builds as a living reference, and axe accessibility and Microsoft Edge arrive on the paid tiers.

Best for: teams that want a designer sign-off workflow and a permalinked published Storybook. See how the pricing works in Chromatic pricing explained.

Percy is BrowserStack's visual testing product. It wires in through percySnapshot() calls you add to your tests, and its advantage is the wider BrowserStack ecosystem: cloud rendering, a real-device cloud, and App Percy for native iOS and Android. If your migration also needs cross-device or native-app coverage, that is a genuine edge.

Best for: teams already on BrowserStack, or anyone who needs real-device and native-app visual testing. See the best Percy alternatives.

If you self-hosted Lost Pixel to avoid a per-snapshot bill, Playwright's built-in toHaveScreenshot is the simplest way to stay free and local. It captures a page or element and compares it to a baseline PNG committed beside the test, with mask, threshold, and maxDiffPixelRatio to keep noise down. What you give up is what the hosted tools sell: baselines still live in your repo, they differ across operating systems, and a change lands as a red test with no history, review UI, or verdict.

Best for: small suites you are happy to review yourself, entirely inside your own CI.

You do not have to move immediately. The OSS core still runs, so if you self-host it, keep baselines in your repo, and are comfortable maintaining an archived dependency, it will keep passing and failing PRs as it does today. The reasons to migrate are forward-looking: no more upstream fixes or features, no managed review UI, and the risk that a future Node, browser, or CI change breaks a project nobody is maintaining. If your suite is small and stable, that risk is low for a while. If it is central to how you ship, move before it bites.

It depends on what you valued in Lost Pixel. If it was the open-core, capture-in-CI model, Argos is the closest. If it was Storybook, Chromatic. If you need real devices, Percy. If you want to stay free and local, Playwright. And if you would rather stop maintaining visual testing infrastructure altogether and let an AI judge do the triage, UI Verify replays your existing tests, judges each change, and exposes review over MCP.
