Keploy
What it is
Keploy turns application traffic into tests and dependency sandboxes for local development, CI, and Kubernetes verification. It captures incoming requests and outgoing dependency calls through eBPF and network-level interception, without requiring application code changes, then replays recorded traffic as regression tests with mocks and isolation. The Playground plan can generate API tests from OpenAPI or Postman inputs, with AI expanding edge cases. Listed support includes HTTP(S), HTTP/2, gRPC, Protobuf, GraphQL, Kafka, MySQL, MongoDB, Redis, DynamoDB, Postgres, and RDS. CI/CD integrations include GitHub, GitLab, Jenkins, and Argo. A Chrome extension captures XHR and fetch traffic, including headers, cookies, and authentication context, and exports calls as cURL, JSON, or Keploy YAML. The core local record-and-replay platform is open source under Apache 2.0. Enterprise features include private or air-gapped deployments, SSO and RBAC, and dedicated support. The Pro CI replay plan uses a Keploy API key.
