Accelerate Test Debugging
Full-Stack Visibility in One Timeline
Multiplayer captures complete test execution context that traditional testing tools miss:
- User behavior and interactions captured at every step
- Frontend screens showing exactly what the test saw
- Backend traces revealing service-level execution
- Complete logs from all system components
- Request and response payloads with full header content
- Service map visualization showing component interactions
- Downstream consequence analysis across the stack
Key Benefits for Test Debugging
When AI coding assistants have access to Multiplayer's full-stack session recordings, development workflows transform:
Works Seamlessly with Your Existing Test Stack
Keep your current setup (Cypress, Playwright, Selenium, Puppeteer) and add the missing layer of visibility. Multiplayer integrates alongside your E2E tools to show why tests fail, eliminating guesswork and cutting mean time to resolution.
No More Wasted Hours Reproducing Failures
See exactly what happened the first time. Multiplayer correlates frontend, backend, request/response content and headers in one replay, giving you immediate answers. You can even auto-generate runnable test scripts directly from failed sessions.
Executable Context
Every session recording becomes a living, interactive artifact. Replay failures, inspect full-stack data, validate fixes before deployment, and share recordings with teammates or AI assistants, all from one place.
Reduce Technical Debt
By visualizing real system behavior in context, you make informed architectural and testing decisions. No blind patching, no side effects, just cleaner fixes and more stable code over time.
Interactive Notebooks for Regression Testing
Full-stack session recordings automatically convert into interactive Notebooks that enable QA and developers to:
- Generate immediate test scripts for regression testing
- Create live fix testing environments
- Execute API calls and code snippets directly from the notebook
- Chain APIs and code in sequence for validation
- Document test failures and intended behavior
- Share reproducible debugging scenarios across teams
Capture Every Failure, No Matter When It Happens
Debugging failed tests is only possible if you’ve actually captured the failure.
That’s why Multiplayer supports three recording modes, so no bug slips through unnoticed.
On-Demand Recording: Trigger a full-stack session recording exactly when you need it. Perfect for reproducing known issues or debugging specific test runs.
Continuous Recording: Keep a lightweight rolling buffer of activity that auto-saves whenever a frontend or backend exception or error occurs. This hybrid mode means you never lose the context around an unexpected failure, even when you weren’t recording.
Remote Recording: Silently capture issues from users, CI environments, or production systems without any manual action, ensuring complete visibility across environments.
With Multiplayer, whether a test fails during local dev or deep in CI, you always have the full story ready to replay and debug.
