No Flaky Tests,Only Rock Solid, Reliable Tests
Other test case generators fail on dynamic data. Keploy automatically detects and ignores noisy fields like timestamps and random IDs.
Without Keploy
Every timestamp or random ID changes, causing test failures even though your app works perfectly
With Keploy
Noisy fields are automatically ignored. Tests focus on what matters

Smart Bug Detection Using AI
Keploy uses AI to automatically analyze traffic, generate tests, and actively hunt for bugs with confidence scores to prioritize issues.
Proactive Bug Detection: AI analyzes API behavior to spot unexpected errors and inconsistent results automatically.
AI Confidence Scores: Each bug is assigned a confidence score to help you prioritize real issues first.
Smart Pattern Recognition: Learns from API patterns to identify edge cases and negative scenarios others miss.
Automatic Deduplication
Keploy intelligently identifies and removes duplicate test cases based on request/response patterns, keeping your test suite lean and fast without manual intervention.
Hash-Based Detection
Creates unique fingerprints for each test based on request/response data
Automatic Cleanup
Removes redundant tests while preserving unique coverage
Faster Execution
Run only unique tests, reducing execution time significantly

Tests that don't break in CI/Cd Pipelines
Keploy makes your test data and test runs behave the same on your laptop and inside CI pipelines.
Problem
Tests that work locally fail in CI/CD due to environment differences and missing setup.
Keploy Solution
Keploy tests run consistently in any CI/CD environment with zero configuration.
Key Benefits
- Works seamlessly with GitHub Actions, GitLab CI, Jenkins
- Zero environment-specific configuration
- Reproducible results across all environments
- Tests run deterministically in CI pipelines
- Built-in reporting and failure tracking

Automatic Test Generation
Keploy records real API traffic and turns it into test cases automatically. No manual scripting needed—your regression suite is always based on actual user flows.
FAQs
Regression testing checks if new code changes have unintentionally broken existing features. Keploy makes this process easy by automatically recording API calls during normal usage and turning them into repeatable tests. When you make changes to your code, Keploy replays these tests to catch any unexpected behavior or regressions.
No, that's one of the best parts! Keploy captures real API traffic and generates regression tests for you. This saves you time and ensures your tests reflect actual usage patterns.
Keploy replays recorded API calls in a test environment and compares the new responses to the original ones. If there are any differences that shouldn't be there, Keploy flags them as potential regressions.
No, that's one of the best parts! Keploy captures real API traffic and generates regression tests for you. This saves you time and ensures your tests reflect actual usage patterns.
Yes! Keploy is designed to capture session data, headers, and dependencies between requests. This means it can handle multi-step workflows and stateful interactions, not just simple one-off API calls.
Absolutely. Keploy can mock databases and third-party services, so your regression tests run in isolation and aren’t affected by changes or downtime in external systems.
Yes! Keploy works well with CI/CD tools, so you can automatically run regression tests on every code change, ensuring issues are caught early.
Definitely. Keploy is built to scale, making it a great fit for microservices and large projects. It can record and replay API calls across multiple services, helping you catch regressions anywhere in your architecture.
