5 Free Applitools Alternatives for Visual Testing

Applitools is a powerful visual testing tool, but its pricing model — based on Test Units with undisclosed rates — doesn't fit every budget. Fortunately, free alternatives exist that let you start visual testing without any upfront investment.

Here are 5 alternatives to Applitools, each with its own strengths and limitations.

1. BackstopJS

What it is

BackstopJS is an open source visual regression testing tool that runs from the command line. It captures screenshots of your application and compares them pixel by pixel to detect differences.

What it does well

  • Completely free: it's an open source project under the MIT license
  • Automation-friendly: integrates easily into CI/CD pipelines
  • Flexible configuration: lets you define precise test scenarios with CSS selectors
  • Cross-browser: uses Puppeteer or Chromium under the hood
  • Report generation: produces visual reports with differences highlighted

Configuration example

Here's a BackstopJS configuration example for testing a home page:

{
  "id": "my_site",
  "viewports": [
    { "label": "desktop", "width": 1280, "height": 720 },
    { "label": "mobile", "width": 375, "height": 667 }
  ],
  "scenarios": [
    {
      "label": "Home page",
      "url": "https://mysite.com",
      "referenceUrl": "https://mysite.com",
      "selectors": ["header", "main", "footer"],
      "delay": 500
    }
  ]
}

This configuration captures the header, main content, and footer on both desktop and mobile. The delay option waits 500 ms before capture, useful for pages with animations or asynchronous loading.

Real-world use cases

BackstopJS shines in several situations:

  • Validation after a CSS refactor: after updating your CSS framework (Tailwind, Bootstrap), run BackstopJS to verify that the layout hasn't changed unexpectedly.
  • Responsive design testing: thanks to configurable viewports, you can verify that your site displays correctly across all screen sizes.
  • Continuous monitoring: integrated with a cron job or webhook, BackstopJS can monitor your production site and alert you if a visual change is detected.

Its limitations

  • Technical: requires JavaScript and command-line skills
  • Installation required: you need to install Node.js and set up the environment
  • Maintenance: test scenarios must be updated manually as the site evolves
  • No AI: the comparison is purely pixel-by-pixel, which generates false positives

When to use it

BackstopJS fits development teams with technical skills who want a free, customizable solution. It's particularly well suited for projects where you want full control over the configuration.

2. Percy (open source version)

What it is

Percy, developed by BrowserStack, offers an open source version of its visual testing tool. Percy works as a service that captures and compares screenshots in an automated way.

What it does well

  • Native CI/CD integration: Percy integrates with GitHub Actions, CircleCI, Travis CI, and many more
  • Collaborative web interface: teams can review visual changes together
  • Branch management: visual changes are tied to pull requests
  • Multiple SDKs: supports Selenium, Cypress, Playwright, Puppeteer, and Ruby Capybara

Its limitations

  • Limited free plan: the free version is reserved for open source projects or has monthly screenshot limits
  • Cloud dependency: screenshots are stored on Percy's servers
  • Technical configuration: requires SDK installation and modifying test code

GitHub Actions integration example

Percy plugs directly into your CI/CD workflows. Here's a GitHub Actions configuration example:

name: Visual Testing
on: [push, pull_request]
jobs:
  percy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 20
      - run: npm ci
      - run: npm run test:visual
        env:
          PERCY_TOKEN: ${{ secrets.PERCY_TOKEN }}

With this configuration, every push or pull request triggers visual tests. Percy compares screenshots against the baseline and displays differences directly in the pull request interface.

Real-world use cases

  • Pull request reviews: Percy flags visual changes directly in the PR, letting reviewers see the visual impact of the code.
  • Design systems: teams maintaining component libraries use Percy to verify that component updates don't break existing appearance.
  • Open source projects: the free plan for open source projects lets contributors visually verify their contributions.

When to use it

Percy is relevant for open source projects or teams already using BrowserStack who want smooth integration into their development workflow.

3. Playwright Screenshots

What it is

Playwright, Microsoft's browser automation framework, offers native screenshot capture and visual comparison features. It's an integrated solution with no extra tools to install.

What it does well

  • Already in your stack: if you use Playwright for functional tests, screenshots are free
  • Cross-browser: natively supports Chromium, Firefox, and WebKit
  • Built-in comparison: the expect(page).toHaveScreenshot() method automatically compares screenshots
  • Free and open source: Playwright is under the Apache 2.0 license

Its limitations

  • Basic comparison: no AI, pixel-by-pixel comparison only
  • Manual configuration: you need to write test code for each page to check
  • Sensitivity: anti-aliasing differences or font rendering generate false positives
  • No review interface: no collaborative dashboard to visualize differences

Playwright test example

const { test, expect } = require('@playwright/test');

test('Home page - visual capture', async ({ page }) => {
  await page.goto('https://mysite.com');
  await expect(page).toHaveScreenshot('home-desktop.png');
});

test('Home page - mobile version', async ({ page }) => {
  await page.setViewportSize({ width: 375, height: 667 });
  await page.goto('https://mysite.com');
  await expect(page).toHaveScreenshot('home-mobile.png');
});

The first run creates the reference screenshots. Subsequent runs automatically compare new captures against the baseline. If differences are found, Playwright generates a comparison report.

Real-world use cases

  • React/Vue/Angular component tests: Playwright can capture individual components in addition to full pages, ideal for design systems.
  • Cross-browser verification: the same test runs on Chromium, Firefox, and WebKit without modification, ensuring visual consistency across browsers.
  • Dynamic state testing: by combining actions (clicking, filling out a form) and captures, you can visually verify different UI states (empty form, with errors, with success).

When to use it

Playwright Screenshots is ideal if you already use Playwright and want to add a layer of visual verification without another tool.

4. LambdaTest (Free Tier)

What it is

LambdaTest is a cloud testing platform that, among other features, offers visual testing. The free plan lets you explore the platform's capabilities.

What it does well

  • Complete ecosystem: LambdaTest goes beyond visual testing with functional testing, accessibility, and real mobile device testing
  • Cross-browser cloud: access to over 3,000 browser/OS combinations
  • Many integrations: CI/CD, test management tools, collaboration tools
  • Generous free plan: lets you test with reasonable limits

Its limitations

  • Free plan limits: monthly caps on minutes and screenshots
  • Complexity: the richness of the ecosystem can be intimidating for beginners
  • SDK required: technical integration is still needed to automate visual tests

Real-world use cases

  • Cross-browser testing: if your application must work on Chrome, Firefox, Safari, and Edge, LambdaTest lets you capture screenshots on each of these platforms without local infrastructure.
  • Accessibility testing: LambdaTest integrates accessibility checks (WCAG) in addition to visual testing, providing dual oversight.
  • Teams with security constraints: LambdaTest offers testing features on secured environments, useful for enterprises with strict security policies.

When to use it

LambdaTest fits teams looking for an all-in-one platform and willing to invest in a paid plan as their needs grow.

5. Delta-QA

What it is

Delta-QA is a visual testing solution designed for simplicity. Unlike the other tools in this list, Delta-QA is built for teams that want to start visual testing without technical skills.

What it does well

How to choose?

The choice depends on your context:

  • You're a developer and want full control: BackstopJS or Playwright
  • You're in open source: Percy
  • You want a complete platform: LambdaTest
  • You want simplicity, no code and no training: Delta-QA

Questions to ask yourself to make the right choice

To refine your decision, ask yourself these questions:

  1. Does anyone on my team know how to code in JavaScript or Python? If not, rule out BackstopJS, Playwright, and Cypress Visual. Turn to Delta-QA or LambdaTest.
  2. Is my project open source? If yes, Percy and Chromatic offer dedicated free plans.
  3. Do I need to test on real mobile devices and browsers? If yes, LambdaTest or Percy (via BrowserStack) are the most complete options.
  4. Am I already using a test framework? If you're on Playwright, add toHaveScreenshot(). If you're on Cypress, use a snapshot plugin. If you're on Storybook, Chromatic is the natural choice.
  5. What's my long-term budget? Free tools (BackstopJS, Playwright) require maintenance time. Paid tools (Percy, Chromatic, LambdaTest) cost money but reduce the workload. Delta-QA sits between the two: no upfront cost, no technical maintenance.
  6. Do I have to report back to non-technical stakeholders? If your manager or client wants to see visual results without going through a developer, a collaborative web interface (Percy, LambdaTest, Delta-QA) is essential.

Why Delta-QA?

Among all these alternatives, Delta-QA stands out thanks to its radically simple approach:

  • Zero installation: no SDK, no dependencies, no technical configuration
  • Zero skills required: no need for automated testing training, no TAU (Test Automation University), no need to know JavaScript or Python
