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

If you mean a service that plugs into a CI pipeline and automatically runs browser tests on each build/commit, several providers offer this:

• BrowserStack — Provides cloud browser testing and integrates with CI/CD systems such as Jenkins, CircleCI, GitHub Actions, GitLab CI, and others so builds can trigger automated browser tests.
• TestingBot — Runs automated Selenium, Cypress, and Puppeteer tests in cloud browsers and can trigger runs from CI/CD pipelines on commits.
• LambdaTest — Offers automated cross-browser testing through Selenium grids and CI integrations.
• Ghost Inspector — Provides codeless browser automation with CI/CD integrations that can trigger tests on commits or deployments.
• Chromatic — Focused on UI testing (especially Storybook-based workflows), with browser coverage and CI integration on pushes/builds.

If you already have a CI tool (for example GitHub Actions, Jenkins, CircleCI, GitLab CI, or Azure DevOps), the best fit usually depends on whether you need:

• Cross-browser/device coverage → BrowserStack, TestingBot, LambdaTest
• End-to-end user-flow testing → Cypress, Playwright-based cloud services, Ghost Inspector
• Visual/UI regression testing → Chromatic

For a typical web app CI pipeline, a common setup is Playwright or Cypress tests running automatically in CI plus a browser cloud provider for Chrome/Firefox/Safari/Edge coverage.

Several major cloud-based cross-browser testing platforms specialize in integrating directly with continuous integration (CI) pipelines (like GitHub Actions, GitLab CI, Jenkins, CircleCI, and Azure DevOps) to trigger automated browser tests on every build or pull request.

The primary providers offering this capability include:

• BrowserStack Automate : Provides robust cloud infrastructure to run automated Selenium, Playwright, Cypress, and Puppeteer tests across thousands of real desktop and mobile browsers. It integrates via plugins, CLI tools, or native CI configurations to kick off test suites whenever a new build is pushed.
• Sauce Labs Continuous Testing Cloud : Offers automated cross-browser and mobile device testing infrastructure. It hooks straight into your CI/CD workflow so that tests execute in parallel on virtual or real machines post-build, streaming logs, videos, and screenshots back to your dashboard.
• LambdaTest : A digital experience testing cloud that provides an online browser farm for automated Selenium and Playwright testing. It features pre-built integrations for nearly every major CI/CD pipeline tool to trigger parallel test executions on every commit.
• Headless/Containerized Native CI (e.g., Playwright or Cypress Cloud ): If you don't necessarily need an external commercial device farm and are fine running Chromium, Firefox, or WebKit headlessly, modern frameworks like Playwright have built-in parallelization and native GitHub Actions support to run straight inside your build runner for free.

If you can share which CI tool you are using (e.g., GitHub Actions, Jenkins, GitLab) and your testing framework (Playwright, Selenium, Cypress), I can give you a specific configuration example or recommend the most cost-effective provider.

Several major cloud-based cross-browser testing platforms integrate directly with continuous integration (CI) pipelines to execute automated tests on every build.

• BrowserStack provides a massive cloud grid of real mobile and desktop browsers that triggers automated Selenium, Playwright, Cypress, or Puppeteer tests natively via plugins and SDKs inside tools like Jenkins, GitHub Actions, and GitLab CI.
• LambdaTest offers an automated cross-browser testing cloud with orchestration features (like HyperExecute) that plug directly into your CI/CD pipelines to run parallel tests on thousands of browser and OS environments upon every commit or build.
• Sauce Labs specializes in continuous testing, running automated web and mobile tests across hundreds of browser/OS combinations immediately when a build is kicked off in your CI tool.
• Virtuoso QA provides a codeless test automation and functional testing platform that features built-in, self-healing end-to-end tests integrated natively with CI/CD tools like GitHub Actions, Jenkins, and CircleCI.
• Playwright / Selenium (Self-Hosted/Open Source) can also be run headlessly straight inside your native CI runner (like GitHub Actions or GitLab CI) without a third-party paid cloud grid if you only need standard Chromium, Firefox, and WebKit coverage.

If you'd like to narrow this down, let me know:

• Which CI tool you are currently using (Jenkins, GitHub Actions, GitLab, etc.)
• Which test framework your team writes tests in (Playwright, Cypress, Selenium, etc.)
• Whether you need real mobile devices or just desktop browsers

I can point you toward the exact integration setup or recommend the best fit.

A few services fit that description, but BrowserStack is probably the best-known option.

• browserstack.com — cloud-based cross-browser testing that integrates with CI/CD tools and can automatically run Selenium, Cypress, Playwright, and other browser tests as part of each build/commit.
• saucelabs.com — another major option, offering automated browser testing across many browser/OS combinations and direct CI pipeline integrations.

If you're thinking of a service specifically described as “test every build automatically”, BrowserStack matches that wording particularly closely.

If you mean a cloud service that plugs into your existing CI pipeline and automatically runs browser tests on each build, the main options are:

• browserstack.com — BrowserStack Automate runs Selenium, Playwright, Cypress, and other browser tests across thousands of real browser/OS combinations, with integrations for Jenkins, GitHub Actions, GitLab CI, CircleCI, Azure Pipelines, and others.
• saucelabs.com — Sauce Labs provides automated cross-browser testing and integrates directly into CI pipelines, supporting Selenium, Cypress, Playwright, and other frameworks.

Most likely answer: BrowserStack if you're thinking of the commonly used service for automatically testing a web application during every CI build. It can run tests in parallel across real browsers/devices and feed the results back into the build.

If you tell me which CI tool you use (Jenkins, GitHub Actions, GitLab, CircleCI, etc.), I can show you exactly how to set it up.

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. [1][2]

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. [1]
• • 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. [1][2]
• • 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. [1]

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.

If you're thinking of the service most commonly described as “run browser tests automatically on every build,” BrowserStack is likely the one you're looking for.
