Simulate APIs with one behavior per endpoint
Fixed responses, relative templates, or simulation functions — transport-agnostic and ready for tests, Node, or the browser.
Three behaviors
Fixed
Always return the configured response — health, constants, stable fixtures.
Relative
Render JSON with tokens from the request and API-local data.
Simulation
Run a function for branching, validation, and computed responses.
Product-owned package simulators ship their own logic and data. This core stays zero runtime dependencies and does not load fixtures from disk or Memorix.
