Mimicry is a mock REST API generator for frontend teams that lets users create dynamic mock endpoints with realistic JSON in seconds, with no backend required. It supports importing OpenAPI/Swagger contracts to instantly generate hosted mock endpoints, full CRUD operations with data relations, and 'Chaos Mode' to simulate network instability, errors, and malformed data for resilience testing. It also ships a remote MCP server so AI assistants like Claude Code, Cursor, Windsurf, and Antigravity can query and manage mock workspaces.
