Test and Debug on a Scalable Selenium Cloud Grid
Cover thousands of browser-OS combinations, run tests in parallel, and debug failures with full logs and video.
Cloud Selenium Grid
Selenium Grid on Cloud with Real Browser-OS Combinations
Run Selenium tests on real browsers and operating systems. Pick the exact browser-OS combinations your users have. No virtual machines, no emulators to maintain.
Get Started For Free
- Validate across 3,000+ real browser-OS combinations spanning browser versions and operating systems.
- Test newly released browsers and legacy versions with day-zero coverage for both.
- On-demand cloud infrastructure means no browser environments to provision, configure, or maintain.
Parallel Test Execution
Run Selenium Tests in Parallel
Run your Selenium suite across many browser-OS combinations at once. Parallel execution cuts runtime from hours to minutes. Get faster feedback on every run.
Get Started For Free- Run as many concurrent sessions as your plan supports, scaling as you grow.
- Tests distribute automatically across nodes with no manual splitting or allocation.
- Failed tests retry on fresh nodes to isolate infrastructure flakiness without breaking the run.
RICH TEST LOGS
Debug Selenium Failures from the First Run
See why a Selenium test failed without reproducing it locally. Every session is recorded end to end. Diagnose failures on the first run.
Get Started For Free- Replay failures from video, visual, command, network, console, Selenium, and telemetry logs.
- Screenshots and a visual timeline pinpoint where the UI broke without a local rerun.
- Session telemetry surfaces flaky behavior and separates real bugs from environment noise.
COMPLIANCE READY
Run Selenium Tests Without Compromising Security
Run Selenium tests on a secure, compliant cloud Grid. It is SOC 2 Type II, GDPR, and CCPA certified. Your test data stays isolated.
Get Started For Free- Test data is encrypted at rest and in transit on every Selenium run.
- Browser sessions are wiped after every test, so no data carries over between runs.
- On-premise deployment is available for teams that cannot use public cloud.
INFRA FOR AI AGENTS
Scalable Selenium Browser Infrastructure for AI Agents
Run Selenium automation and AI agents on real cloud browsers. Drive every session at scale with built-in stealth. Control each browser programmatically.
Explore Browser Cloud- Point your existing Selenium WebDriver scripts at the cloud browser with no SDK changes or rewrites.
- Geo-targeted proxies across 180+ locations let every Selenium session originate from the region your test needs.
- Session and authentication state persist across runs, so Selenium sessions keep context without repeating logins.
