What is Keploy?
Keploy is a code verification tool that builds a Digital Twin of production behavior from real application traffic, including incoming API calls and outgoing dependency calls such as databases, queues, caches and third-party APIs. It captures this traffic with eBPF and network-level interception, so no application code changes are needed. The captured behavior is converted into editable YAML tests and mocks.
Once recorded, the tests can be replayed against new builds locally, in CI/CD pipelines or across Kubernetes to catch response, schema, contract and performance regressions. Keploy can also use API schemas and application context to generate extra edge cases and connected flows, and it offers a Chrome extension for browser capture. Developers and coding agents can use it to check AI-generated changes before they are merged or deployed.
Key features
- Records live API traffic and dependency calls via eBPF without code changes
- Converts recordings into editable YAML tests and mocks
- Replays tests in CI/CD, locally or on Kubernetes to detect regressions
- AI generates edge cases and tests from OpenAPI or Postman specs
- Mocks databases, queues, caches and third-party APIs
- Chrome extension for browser and web capture
Who is it for
- Software engineering teams
- Developers verifying AI-generated code
- QA and test automation engineers
- Regulated engineering teams needing compliance controls
Pros and cons
- Works without changing application code
- Open source core under Apache 2.0 license
- Fits into existing CI/CD pipelines such as GitHub, GitLab and Jenkins
- Recording from Kubernetes, staging and production, plus RBAC and SSO, requires the Enterprise plan
- AI credits are limited on the Playground and Pro plans
