Keploy
AI code verification with production traffic digital twins.
Keploy is an open-source API and integration testing platform that turns real application traffic into tests and dependency mocks. It captures incoming requests and outgoing calls to databases, queues, caches, and external APIs using eBPF and network-level interception, without requiring application code changes. The captured behavior becomes editable tests and mocks that can be replayed against new builds to catch response, schema, contract, and performance regressions before code is merged or deployed.
Core capabilities include traffic recording, replay in CI, API test generation from OpenAPI or Postman specs, AI-assisted edge-case expansion, contract testing, load testing, and coverage insights. It supports Node, Go, Java, and Python, with integrations for GitHub, GitLab, Jenkins, and Argo, and can run locally, in Docker, or in Kubernetes. AI features include self-healing tests, bug detection, and edge-case discovery, with support for OpenAI and Gemini or bring-your-own-key models.
Keploy is aimed at engineering teams verifying changes written by AI or humans. It is packaged as an open-source core, a free Playground plan, a seat-based Pro plan with usage-based overages, and a custom Enterprise edition with Kubernetes recording, SSO, RBAC, compliance controls, and air-gapped deployment.
