Visual regression tools all do one job: compare a screenshot with an approved baseline and show you what changed. They differ in where baselines live, who reviews differences, and how the bill is counted. This roundup lists eight, grouped by that, with a one-line “best for”, pricing, free tier, CI support and where each falls short. We make Sybqa, which is on the list because people search for it here, but it does not do baseline comparison, and we say so.

How to read this list
The tools are grouped by operating model: comparison built into a framework you already run, hosted services with a review workflow, and one checker that uses no baselines. The order on the page is a grouping, not a ranking. We have not run these products head to head, so this page makes no claim about which has fewer false positives or catches more change.
Two omissions are deliberate. Cypress has no built-in image comparison; its documentation lists plugins and commercial services, several of which appear below. Lost Pixel’s README says the product is being sunset as the team joins Figma, so we left it out.
Comparison built into your test framework
You store the baselines, usually in the repository, and review differences in a report or a pull request.
Playwright
Best for: Teams already writing Playwright tests who want screenshot assertions with no extra service.
Playwright Test can produce and compare screenshots with toHaveScreenshot(). The first run generates reference screenshots and later runs compare against them. Its documentation warns that rendering can vary with operating system, browser version and hardware, and advises running tests in the environment the baselines were generated in.
Look elsewhere if: you want a review workflow, approvals or non-engineers looking at differences: you store baselines, manage updates and build the review process yourself.
BackstopJS
Best for: Teams that want an open-source, self-hosted comparison with a browser report and a scenario file.
BackstopJS compares screenshots over time in three commands (init, test, approve), renders with Chrome Headless, can drive interactions with Playwright or Puppeteer scripts, offers Docker rendering to avoid cross-platform differences, and writes an in-browser report and JUnit output.
Look elsewhere if: you need a maintained commercial product: its README says it needs a new maintainer or owner. It also has no hosted review workflow.
Hosted services with a review workflow
These store baselines for you and give a team a place to approve or reject each change. They are billed by screenshots, snapshots or checkpoints, so cost follows how many pages, components, browsers and widths you capture.
Percy (BrowserStack)
Best for: Teams that want a free allowance and a review workflow for visual changes in existing Storybook, Playwright or Selenium tests.
Percy captures snapshots from your tests, compares them with approved baselines and highlights differences for reviewers. The free plan includes 5,000 screenshots a month; Desktop is $199 a month and Desktop & Mobile is $599 a month, both billed annually, and its pricing lists a Visual Review Agent that highlights meaningful changes. A screenshot is one page or component in one browser at one width.
Look elsewhere if: you want a flat price: usage is counted per screenshot, so more browsers and widths cost more.
Chromatic
Best for: Storybook-centred teams that want visual tests of components and stories with review and sign-off.
Chromatic takes visual snapshots of Storybook stories and tests and compares them over time. Its TurboSnap feature captures only the tests affected by a change. The free plan includes 5,000 billed snapshots a month on Chrome; Starter is $179 a month for 35,000 and adds Safari, Firefox and Edge; Pro is $399 a month for 85,000.
Look elsewhere if: you do not use Storybook or component-level testing, or you need browsers beyond Chrome on the free plan.
Applitools Eyes
Best for: Teams that want its Visual AI comparison across many browsers and devices, inside tests they already run.
Applitools Eyes compares screenshots with approved baselines using Visual AI and adds an SDK to Playwright, Cypress, Selenium and Storybook tests. The published Starter plan is $667 a month paid annually with unlimited users and 100,000 component checkpoints or 1,000 page checkpoints, with a free trial; Professional and Enterprise are not priced on the page.
Look elsewhere if: you want a low entry price or a permanent free plan: Starter is the highest published entry price on this list.
Argos
Best for: Open-source and small teams on GitHub or GitLab who want usage-based pricing with a free personal plan.
Argos describes itself as open-source visual testing for Playwright, Storybook, Vitest and Cypress, with GitHub and GitLab integration and a CLI and REST API agents can use. The Hobby plan is free for personal projects with up to 5,000 screenshots; Pro starts at $100 a month with 35,000 screenshots included and extra screenshots at $0.004.
Look elsewhere if: you need the free plan on a private organization repository: its pricing page directs those teams to Pro.
Happo
Best for: Teams that want per-snapshot pricing with unlimited users and a free starting tier.
Happo charges by snapshot with unlimited users and concurrent runs on every plan. Free is $0 for 5,000 snapshots a month on Chrome and pauses at the limit; Starter is $149 for 50,000 on Chrome and Firefox; Growth is $399 for 150,000 and adds Safari; Pro is $749 for 300,000 and adds iOS Safari and Edge. Accessibility testing, an API and an MCP server are listed on every plan.
Look elsewhere if: you need browsers beyond Chrome without paying: Firefox starts on Starter, and Safari on Growth.
A checker that uses no baselines
Sybqa (we make this)
Best for: A new or AI-built site where no one has approved a baseline yet and you need to know whether it works and fits on a phone.
Sybqa is not a visual regression tool. It works through journeys in a real browser at desktop (1440 px), phone (390 px) and narrow (320 px) widths, runs accessibility rules and records errors, then reports evidence with screenshots and steps to reproduce. It compares each run with the previous one on findings, not on approved images. The free plan gives 10 runs a month after sign-up without AI review.
Not the right choice if: you need to know a heading moved since the last release or to protect a design system: it keeps no approved baselines and does not diff each build against them.

Which one to choose
Choose Sybqa if
The site is new and nobody has approved a baseline yet.
You want to know whether signup, forms and the phone-width layout work.
You want accessibility rules and error checks in the same run.
Look elsewhere if
You want to catch change nobody asserted on in a design you have settled: any tool above except Sybqa.
You want baselines in your repo and no extra service: Playwright or BackstopJS.
You want a team review and sign-off workflow: Percy, Chromatic, Applitools, Argos or Happo.
A visual comparison and a site check answer different questions and combine well. See visual regression testing vs website QA for how to decide which one you need first.
What this roundup does not claim
We read each vendor’s public pricing, product or repository page on the date shown under Sources. We have not run these tools, so there are no rankings and no measured detection, false-positive or speed figures. Vendor pages state accuracy and time-saving figures that we have not tested and do not repeat. Where a vendor does not publish a price, we say so.
Common questions
What is the best visual regression testing tool?
It depends on where you want baselines to live and who reviews differences. Playwright and BackstopJS keep baselines in your repository at no licence cost. Percy, Chromatic, Applitools, Argos and Happo host baselines and add a review workflow, priced by screenshots, snapshots or checkpoints. The comparison table above sets out pricing, free tier and CI support for each.
Can I start visual regression testing for free?
Yes. Playwright and BackstopJS are open source. Percy, Chromatic, Argos and Happo each list a free plan with 5,000 screenshots or snapshots a month, with limits on browsers, repository type or features, and Applitools offers a free trial.
Does Sybqa do visual regression testing?
Not in the sense these tools do. Sybqa checks journeys, layout at three widths and accessibility, and compares each run with the previous one on findings. It does not keep approved snapshots of every page and diff each build against them.
