About keploy
Keploy is an open source Go project in the API and integration testing ecosystem. It is a developer centric API and integration testing tool that creates safe, isolated production sandboxes for API, integration, and end to end testing. The project records API calls, database queries, and streaming events, then replays them as tests and data mocks. It captures traffic at the network layer with eBPF, so the README says it is code less and language agnostic.
