Sauce Labs
Cloud testing platform that uses AI agents to write, run and analyse web and mobile tests on real and virtual devices.
Sauce Labs is a cloud testing platform for web and mobile software. Its AURA layer uses AI agents to turn plain-language descriptions into executable tests, run them across real devices, emulators, simulators and browsers, and explain failures. Sauce Labs plugs into IDEs, AI coding tools and CI/CD pipelines through plugins, APIs and an MCP server.
Best for Engineering and QA teams that need to verify web and mobile releases across many devices and browsers, including code produced by AI assistants.

What is Sauce Labs?
Sauce Labs is a cloud platform for automated and manual testing of web and mobile applications. The company presents its current offering as AURA, an AI-driven release assurance layer in which agents author tests from natural-language intent, execute them, analyse failures and repair tests when the interface changes. Tests run on infrastructure hosted by Sauce Labs: more than 10,000 real devices and over 3,000 operating system and browser combinations, alongside emulators and simulators. The platform supports Selenium, Appium, Cypress, Playwright, Espresso and XCUITest, and connects to editors such as VS Code, JetBrains and Cursor. Other products cover visual testing, mobile app distribution for beta programmes and production error reporting. Sauce Labs states that its founders created Selenium and Appium and that it holds ISO/IEC 42001, ISO 27001, ISO 27701 and SOC 2 Type II certifications.
Key Features
Intent-Based Test Authoring
Converts a user journey described in plain language into an executable test for frameworks such as Selenium, Cypress or Appium, written inside the IDE.
Real Device Cloud
Gives access to more than 10,000 physical Android and iOS devices, with programmatic device control for automated and agent-driven workflows.
Virtual Device Cloud
Runs automated and manual sessions on desktop browser and OS combinations plus mobile emulators and simulators, using virtual machines that are discarded after one use.
AI Failure Analysis
Sauce AI for Insights reads test results across runs, points to the likely root cause, flags flaky patterns and suggests a fix.
Mobile App Distribution
Shares pre-release builds with beta testers under SSO and role-based access, and lets teams reproduce a reported bug on the same device model.
Error Reporting
Collects production errors as structured data with real-time alerts and deduplication so recurring crashes can be traced.

Use Cases
- Checking AI-Generated Code
- Run generated changes against real devices before release instead of relying only on code review.
- Cross-Browser Regression Runs
- Execute a suite in parallel across browser and operating system combinations from a CI/CD pipeline.
- Mobile App Testing
- Test Android and iOS builds on physical handsets with Appium, Espresso or XCUITest.
- Beta Programmes
- Distribute a build to a controlled tester group and collect validation ahead of launch.
- Triage of Failed Builds
- Use the video, screenshots, logs and network captures from each run to explain why a test failed.
Things to know
- AI agents sit in the Enterprise tier
- The pricing page places the two Sauce AI agents, one for test authoring and one for insights, in Enterprise Level offerings, while the home page announces that Sauce AI is part of free trials.
- Plans are split by testing type
