MirageAPI vs Mockoon
Mockoon is an open-source (MIT) desktop application for designing mock APIs, with a CLI and Docker image for running them. It shines when you want fine-grained control over every route. MirageAPI takes the opposite approach: your OpenAPI spec is the single source of truth and the mock is generated from it automatically.
