Percy Alternatives: 7 Visual Testing Tools Compared

Percy is a capable visual testing platform, and if it fits your workflow and budget there is no reason to move. But “percy alternatives” is a search a lot of people make, and in our experience it comes down to one of four things: the price at the volume you actually use, the fact that it wants to live inside a test suite, the BrowserStack bundle it now sits in, or its server-side rendering model.

Which of those is driving you decides which tool to look at, so this page is organised that way. Every price below is from the vendor’s own pricing page, checked on 25 September 2026.

Desktop25,000$449/mo$549/mo$0.036 each
Desktop & Mobile25,000$599/mo$729/mo$0.048 each

The free tier is genuinely good: 5,000 screenshots a month with unlimited users and unlimited projects. Paid plans carry a year of build history.

The part that catches people out is the counting. In Percy’s model a screenshot is one page or component rendered in one browser at one width — so the browsers and widths multiply. Percy’s own support documentation works the example: one page across Chrome and Edge at three widths each is six snapshots. Failed build attempts count too, because a browser was opened either way.

That is why the jump from “we test 30 pages” to “we’re over the plan” happens faster than teams expect, and why the $199 entry point is the number most people are reacting to when they go looking.

Diffy

Diffy is ours. It is URL-based: you paste URLs or import a sitemap, pick breakpoints, and compare two environments or the same site before and after a change. There is no SDK, no test code and nothing installed on the site, which is the main structural difference from Percy.

  • Free: 500 screenshots a month, production and staging, every stabilising setting (masking, cookies, headers, injected CSS and JavaScript, mock content, login), one month of history.
  • Paid: from $67/month billed annually ($80 monthly) for 2,000 screenshots, adding CI and API access and six months of history. Then $125/mo for 8,000 and $250/mo for 30,000, also billed annually. See pricing.
  • Counting: one page at one breakpoint is one screenshot, same multiplication as Percy — the difference is the price per unit and where the ladder starts.
  • Browsers: Chrome and WebKit, widths from 240px to 2000px.

Where it beats Percy: the entry price, and not needing a test suite. A 20-page site at three breakpoints run daily is about 1,800 screenshots a month — $67 here against $199 there.

Where it does not: fewer browsers (no Firefox or Edge), no native mobile apps, and no component-level testing.

Full head-to-head: Diffy vs Percy

Argos

The closest thing to “Percy but cheaper” for teams that do have a test suite. Argos is MIT-licensed code run as a hosted service — its docs say self-hosting is not officially supported. You upload screenshots from an existing Playwright, Cypress, Storybook, Vitest, Puppeteer or WebdriverIO run and review them on the pull request.

Free is up to 5,000 screenshots. Pro starts at $100/month with 35,000 screenshots included and $0.004 for each extra one — against Percy’s $0.036.

Argos describes its comparison as deterministic pixel diffing rather than AI, built on the open-source odiff library with several diff passes and pixel clustering to separate noise from real change.

Where it beats Percy: price per screenshot, by roughly an order of magnitude at the margin, and a review flow built around the pull request.

Where it does not: it needs a test suite, and it is a smaller company than BrowserStack if that matters to your procurement.

Chromatic

If you came to Percy to test a component library, Chromatic is the more natural home. Made by the Storybook team, though it now also supports Playwright, Cypress and Vitest browser-mode tests, so Storybook is not a hard requirement.

Free is 5,000 billed snapshots a month on Chrome only. Starter is $179/month for 35,000 snapshots across Chrome, Firefox, Safari and Edge, with overage at $0.008; Pro is $399/month for 85,000. Billing is monthly — there is no self-serve annual discount.

TurboSnap reduces usage by copying snapshots for tests your commit did not affect, which is the lever that makes the snapshot allowance go further than the raw number suggests.

Where it beats Percy: component-level testing, and more included snapshots for less money at the entry tier.

Where it does not: whole-page testing of a live site is not what it is for, and the free tier is Chrome-only.

Playwright’s built-in screenshot assertions

If you already run Playwright, you already have visual testing and it costs nothing: await expect(page).toHaveScreenshot(), Apache-2.0.

The capture options are better than people expect. mask takes an array of locators and covers each with a box, animations defaults to disabled and stops CSS animations and transitions, and sensitivity is tunable with threshold (default 0.2), maxDiffPixels and maxDiffPixelRatio.

The catch is environment discipline, and Playwright’s own documentation is blunt about it: rendering varies by host OS, version, settings, hardware, headless mode and more, which is why baselines are named per browser and platform — and why a baseline captured on a Mac will not match a Linux CI run.

Where it beats Percy: unlimited screenshots, no vendor, no per-browser multiplication.

Where it does not: baselines live in your repository and grow, review is a local HTML report rather than a shared UI, and nobody outside the engineering team is going to approve a change.

BackstopJS

The open-source option that works the way Percy’s percy snapshot sitemap mode works: URL-based, no test suite. You describe scenarios in backstop.json, then run backstop test and backstop approve. MIT licensed. Comparison is Resemble.js with a misMatchThreshold (default 0.1), and it has the settings a real site needs: hideSelectors, removeSelectors, delay, onReadyScript, clickSelector. It drives Puppeteer or Playwright.

One thing to check before adopting: its last npm publish was 6.3.25 in September 2024 and the GitHub releases page stops at v5.0.2 from 2023. The repository is not archived and carries no unmaintained notice, but that is two years without a release, and we could not find an official explanation.

Where it beats Percy: free, unlimited, URL-based.

Where it does not: you own the maintenance, the baselines and the CI plumbing.

Applitools

If you are leaving Percy because you need more — more browsers, native mobile apps, a large QA organisation — rather than less, this is the direction. Eyes captures a DOM snapshot in your test and renders it across environments in the Ultrafast Grid, and Applitools describes its comparison as working at a perceptual level rather than pixel by pixel.

It is the most expensive option here by a distance. No free plan, only a trial; Starter is $667/month paid annually for 100,000 component checkpoints or 1,000 page checkpoints, and everything above that is contact-sales.

They advertise “99.999% Visual AI precision” — their figure, published without a linked methodology, so treat it as marketing rather than a benchmark.

Where it beats Percy: breadth of coverage and enterprise features.

Where it does not: price, and the same test-suite requirement you already have.

Sauce Labs Visual and TestMu AI SmartUI

Both put visual testing inside a browser and real-device grid, which is the right shape if you need the grid anyway.

Sauce Labs Visual has no permanent free tier, just a 28-day trial. The cheapest plan that includes visual testing is Virtual Device Cloud at $149/month billed annually, and it includes 500 snapshots a month — not many — with no published rate for extras.

TestMu AI SmartUI is the former LambdaTest, rebranded on 12 January 2026. Free is 2,000 screenshots valid for lifetime rather than monthly; SmartUI Visual Regression starts at $199/month billed annually for 15,000 screenshots a month.

Where they beat Percy: device breadth.

Where they do not: visual testing is a feature of a bigger product rather than the product, and the snapshot allowances are small relative to the price.

What you give up by leaving Percy

Worth being straight about, because none of the tools above match all of it:

  • Server-side rendering of a DOM snapshot. The Percy SDK serialises the DOM in your test run and Percy renders it on its own infrastructure, with JavaScript disabled by default since the page has already executed (docs). That makes rendering consistent between runs in a way live browser capture is not. The trade-off is that what Percy renders is not always what a browser does live.
  • Chrome, Firefox, Edge and Safari (enabled by default on every new project), plus real mobile devices on the Desktop & Mobile plan. Diffy does Chrome and WebKit; Argos and Chromatic have their own matrices; Playwright is whatever you run.
  • Unlimited users on every plan, including free. Not universal among the alternatives.
  • One of the most generous hosted free tiers here at 5,000 screenshots a month. Chromatic matches the number but restricts its free tier to Chrome. If the free tier covers you, moving may cost you more than it saves.
  • A year of build history on paid plans.

Before you migrate

Three practical things, whichever way you go:

  1. Assume baselines do not transfer. None of these tools documents importing another’s baselines, so expect to capture a fresh one and approve a noisy first run. Plan the switch for a quiet week, not the day before a release.
  2. Recount your volume in the new tool’s unit. “10,000 screenshots” means different things depending on whether browsers, widths and component states multiply. Work out your real monthly number for each candidate before comparing prices — the answer often changes the ranking.
  3. Decide who reviews. This is the question that actually determines whether visual testing survives. If approvals belong to developers in a pull request, Argos or Chromatic fit. If a QA lead, a project manager or a client has to sign off, they need a UI they can use without a git checkout.
