Keploy

Keploy records application traffic and turns it into API, integration, and regression tests with dependency mocks.

Keploy

Keploy is an open-source testing agent and sandboxing platform for developers, QA teams, and engineering teams. It records API calls and network interactions, generates tests, mocks dependencies, and replays traffic locally, in CI, or across Kubernetes.

It supports API, regression, contract, integration, performance, and schema testing, including tests generated from OpenAPI, Postman, cURL, or live traffic. The open-source version is free; cloud plans add team features, Kubernetes recording, dashboards, support, and usage-based costs.

Features

  • Record live API traffic and convert it into executable tests
  • Replay traffic as deterministic regression tests in CI
  • Generate tests from OpenAPI, Postman, cURL, or live traffic
  • Mock databases, external APIs, queues, and other dependencies
  • Generate edge-case, error, and negative tests with AI
  • Detect schema coverage and gaps across API endpoints
  • Self-heal tests after non-breaking API changes
  • Apache 2.0 open-source license

Use cases

  • Generate regression tests from real application traffic
  • Mock databases and third-party services during CI runs
  • Validate API contracts and schema coverage
  • Replay production behavior in staging without affecting users
  • Test legacy applications without code changes or SDK instrumentation
  • Add API quality gates to GitHub, GitLab, or Jenkins pipelines
