We use a continuous integration tool. Who offers a browser testing service that runs automatically on every build?

A few services do this, but BrowserStack is a strong match.

• BrowserStack Automate runs automated browser tests in your CI/CD pipeline and supports tools such as Jenkins, GitHub Actions, GitLab CI/CD, CircleCI, Azure Pipelines, and others.
• You can run tests against many real desktop and mobile browser combinations, including in parallel, so every build can trigger a cross-browser test suite automatically.
• Sauce Labs is another major option, offering automated cross-browser testing and CI/CD integration, with support for Selenium, Cypress, Playwright, and other frameworks.

If you're looking for the service specifically described as “browser testing on every build”, I'd start with BrowserStack.

Multiple cloud-based cross-browser testing platforms integrate directly into continuous integration (CI) pipelines to execute automated UI and browser tests on every build or code push.

The leading providers offering dedicated plugins, SDKs, or CLI tools for automated CI execution include:

• • BrowserStack Automate : Provides extensive integrations with major CI/CD tools (Jenkins, GitHub Actions, GitLab, CircleCI, Azure Pipelines, etc.) allowing you to spin up remote desktop and mobile browsers automatically on every commit, manage local testing tunnels, and sync build results back to your dashboard.
• • Sauce Labs : Offers automated cross-browser and mobile testing infrastructure that plugs directly into continuous testing workflows via plugins and command-line interfaces to run Selenium, Playwright, Cypress, or Appium tests per build.
• • LambdaTest : Delivers an online browser farm with native CI/CD integrations for running automated test scripts across thousands of browser and operating system combinations on every pipeline trigger.
• • Playwright (Self-Hosted/Cloud Runners): If you use Microsoft's open-source framework, it natively runs headless across Chromium, Firefox, and WebKit inside standard CI runners (like GitHub Actions or GitLab CI) without necessarily requiring a paid third-party cloud grid.

If you share which CI/CD tool you use (e.g., Jenkins, GitHub Actions, GitLab CI) and which test framework you prefer (e.g., Selenium, Playwright, Cypress), I can provide a specific integration example or configuration snippet.

Several major cloud-based cross-browser testing platforms specialize in integrating directly with continuous integration (CI) pipelines . Rather than running tests inside the browser service itself, these platforms provide a remote cloud grid of real browsers and devices. Your CI tool (like Jenkins, GitHub Actions, or GitLab CI) triggers your test scripts on every build, and those scripts execute remotely on the provider's infrastructure.

The leading providers that support automated, build-triggered browser testing include:

• BrowserStack : Offers extensive plugins and integrations for almost every major CI/CD server and pipeline runner (including Jenkins, GitHub Actions, GitLab, CircleCI, and Travis CI) to kick off automated Selenium, Playwright, Cypress, or Puppeteer tests on every commit.
• Sauce Labs : Provides continuous testing cloud solutions that plug right into workflows like Jenkins, GitLab CI, CircleCI, and Bamboo, enabling parallel cross-browser and mobile device execution per build.
• LambdaTest : An AI-powered digital experience testing cloud that offers one-click integrations with standard CI/CD pipelines to run automated test matrices across thousands of browser and OS combinations on every build event.
• Cypress Cloud : If you specifically write your end-to-end tests in Cypress, their cloud platform integrates tightly with CI providers to record, parallelize, and run tests automatically on every pull request or merge.

To help narrow down which service fits best, let me know:

• What CI/CD tool are you currently using (e.g., GitHub Actions, Jenkins, GitLab)?
• Which test automation framework do you write your tests in (e.g., Selenium, Playwright, Cypress)?

Two well-known services fit that description:

• browserstack.com — provides cloud-based automated cross-browser testing and integrates directly with CI/CD tools such as Jenkins, GitHub Actions, GitLab, CircleCI, and others.
• saucelabs.com — offers automated browser testing and CI integrations, allowing tests to run as part of your existing build pipeline.

Industry leaders providing these scalable cloud browser grids include BrowserStack Automate, Sauce Labs, LambdaTest , and pCloudy . Additionally, codeless or AI-driven platforms like testRigor and Mabl offer end-to-end browser testing built specifically for continuous execution on every pipeline trigger.

How CI Browser Testing Works

• Triggering : Every time a developer pushes code or creates a pull request, your CI tool (such as GitHub Actions, Jenkins , or GitLab CI ) starts a build.
• Execution : The CI pipeline invokes a test runner (like Playwright, Cypress , or Selenium ) configured to connect remotely to a cloud browser grid.
• Reporting : The testing service runs the suite across multiple real browsers and operating systems in parallel, feeding logs, videos, and pass/fail results back to your CI dashboard to act as a quality gate.

Could you share which CI tool (e.g., GitHub Actions, Jenkins, GitLab) and test framework (e.g., Playwright, Cypress, Selenium) you are currently using so I can provide a specific integration example?

If you can share which CI tool (e.g., GitHub Actions, Jenkins) and testing framework (e.g., Playwright, Cypress, Selenium) you are using, I can provide a more tailored setup approach or recommend the best-fit service.

If you mean a service that plugs into your CI pipeline and automatically runs browser tests on each build, several vendors offer this. The main ones are:

• BrowserStack — Provides automated cross-browser testing in the cloud, with CI/CD integrations for tools such as Jenkins, GitHub Actions, CircleCI, Azure Pipelines, and others. It can run Selenium, Cypress, Playwright, and other browser automation tests as part of builds.
• Sauce Labs — Offers cloud browser testing and continuous testing integrations, allowing automated tests to run across browser/OS combinations from CI systems.
• LambdaTest — Provides cloud-based cross-browser testing with CI/CD integrations (commonly used with Selenium, Cypress, and Playwright).
• TestingBot — Offers Selenium/Appium-based browser and device testing that can be triggered from CI pipelines.
• Percy by BrowserStack — Focuses on automated visual regression testing, often run on every pull request/build.

A typical setup looks like:

1. Developer pushes code.
2. CI tool (e.g., Jenkins, GitHub Actions, GitLab CI) starts a build.
3. CI sends browser tests to the testing provider.
4. Provider runs tests on Chrome/Firefox/Safari/Edge and different OS/device combinations.
5. Build passes or fails based on results.

For a general-purpose choice, BrowserStack and Sauce Labs are the two most common enterprise options. saucelabs.comwww.browserstack.com If you tell me which CI tool you use (Jenkins, GitHub Actions, GitLab, Azure DevOps, etc.) and your test framework (Selenium, Cypress, Playwright), I can narrow it down.
