PARALLEL TESTING
Run Tests in Parallel Across Hundreds of Sessions
Run Selenium, Playwright, or Cypress tests in parallel. Every session starts fresh and isolated.
Get Started For Free- Scale concurrent sessions to match test load with no infrastructure setup needed.
- Isolate each test in a clean browser with no shared state from previous sessions.

FASTER TEST EXECUTION
Run Browser Tests 70% Faster with AI-Native HyperExecute
HyperExecute runs test scripts and browsers on the same cloud machine with zero network latency, matching local speed at cloud scale.
- Reorder test execution based on historical failure data so the most likely failures always run first.
- Stop the build when a critical test fails with no need to wait for the full suite.
- Inspect the exact error type, failing step, and stack trace for every failure in HyperExecute.
The execution time we got using HyperExecute, that's the major differentiator.
