In-Depth Review: What is Keploy?
Keploy is an open-source testing platform that captures real application traffic and converts it into automated tests and dependency mocks. Using eBPF-based network interception, it records requests, responses, and interactions with databases, queues, and external APIs—all without code changes. Developers can replay these tests in local, CI, or Kubernetes environments to instantly detect response, schema, or performance regressions. Keploy helps teams verify AI-generated code, accelerate delivery, and reduce outages. With over 18.4K mocks created, it's trusted by Globality and IdeyaLabs.
Core Features
Record Live Traffic
Capture real application traffic using eBPF without code changes to generate tests and mocks.
Replay in CI
Replay recorded tests in CI/CD pipelines to catch regressions before deployment.
Generate Tests with AI
Use AI to generate additional test cases from API schemas and application context.
API & Schema Coverage
Automatically measure and improve API and schema coverage from real traffic.
Deduplication
Remove duplicate test cases to keep test suites efficient.
Dependency Sandboxes
Create isolated sandboxes for dependencies like databases, queues, and APIs.
