Mimicry

Frictionless Mock API Engine.·mimicry.rest

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.

What it's for

Creating a hosted mock REST API without writing backend codeImporting OpenAPI/Swagger contracts to generate live mock endpointsTesting frontend behavior against realistic dynamic JSON dataSimulating latency, errors, and malformed payloads (Chaos Mode / Field Chaos)Running CRUD resources with relations for demos, tests, and CI/CDConnecting AI coding assistants to a mock workspace via MCPDriving different UI states (empty, error, role-based) via conditional responses
