PlatformWebfree

MockServer is an open-source HTTP(S) mock server and proxy for testing. It mocks dependent APIs, records and inspects live traffic, and injects chaos failures like latency or dropped connections to test how an application handles a misbehaving dependency. It's used by developers and QA teams testing across HTTP, gRPC, WebSockets, and other protocols, run via Docker, Homebrew, or as a JAR.
