Keploy
Keploy turns real application traffic into API tests and dependency sandboxes for local work, continuous integration, and Kubernetes verification. It captures incoming requests and outgoing dependency calls with eBPF and network interception, without application code changes, then replays recordings as regression tests with mocks and isolation. Playground can generate API tests from OpenAPI or Postman inputs, while AI expands edge cases. Listed support covers HTTP(S), HTTP/2, gRPC, Protobuf, GraphQL, Kafka, MySQL, MongoDB, Redis, DynamoDB, Postgres, and RDS. GitHub, GitLab, Jenkins, and Argo are listed CI/CD integrations. A Chrome extension captures XHR and fetch traffic, including headers, cookies, and authentication context, exporting cURL, JSON, or Keploy YAML. The core local record-and-replay platform is open source under Apache 2.0. Plans include free Open Source and Playground tiers, Pro at $19 a month, and Enterprise with discussion-based pricing.
