Traffic-based automatic API test generator

About

• A developer tool that automatically generates API and integration tests from real user traffic
• Running with keploy record, without code changes, captures network-level traffic with eBPF to generate tests and mocks
• Records API calls, DB queries, streaming events, etc. and replays them as tests, enabling offline testing without external dependencies
  • Supports virtualizing the entire infrastructure, including HTTP endpoints, DBs (Postgres, MySQL, MongoDB), and queues (Kafka, RabbitMQ)
• Automatically computes statement/branch coverage for developers, and also computes API schema coverage for QA in a unified way
• AI-based coverage expansion with AI reading Swagger/OpenAPI schemas: detects missing fields, boundary values, and type errors
• CI/CD integration support (GitHub Actions, Jenkins, Kubernetes, etc.)
• Includes collaboration and debugging features such as Mock Registry, Time Freezing, and a console viewer
• Language-agnostic (eBPF-based) — supports all runtimes, including Go, Java, Node.js, Python, and Rust
