Release v0.16.0
Frictionless Mock API Engine.
Develop frontend without depending on the backend. Create dynamic endpoints in seconds and organize your workflow with surgical precision.
OpenAPI Import
From contract to mock API.
Stop rebuilding mocks by hand. Import your OpenAPI or Swagger specification and get shareable endpoints with realistic Faker data in minutes.
- OpenAPI 3.0.x / 3.1.x and partial Swagger 2.0 support (YAML or JSON).
- Three input modes: file upload, public URL, or paste content.
- Preview every importable endpoint, then group operations into CRUD resources.
- Enums, patterns, and common formats map to configurable Faker types.
openapi: 3.0.3 paths: /users: get: responses: '200': schema: ...
Capabilities
Power and Simplicity.
Mocks in seconds
Define the path, choose the method, and your mock is live. No deploy, no waiting.
OpenAPI Import
Turn an API contract into hosted mock endpoints. Upload YAML/JSON, paste content, or fetch a public schema URL.
Dynamic Data
Native Faker integration for realistic responses every time.
Multi-Project
Isolate your mocks by environment or client in dedicated projects.
API Keys
Protect your endpoints and use them in your CI/CD pipelines with ease.
Activity Logs
Monitor every single request in real-time. Instant debugging.
Chaos Mode
Simulate network instability, variable latency, random failures, and malformed payloads to build truly resilient frontends.
Conditional Responses
Return different status codes and payloads from a single endpoint based on query, header, or body. Drive every UI state — empty, error, role-based — without spinning up extra mocks.
MCP Server
Connect Claude Code, Cursor, Windsurf, and other AI assistants directly to your mock workspace. Query and manage projects, endpoints, and logs through natural language.
{ "id": 1024, "email": null, "status": "invalid" }
Real-time Chaos Simulation
Test like a Pro.
Don't just test the "happy path". Configure realistic failure profiles and inject field-level data mutilations (Field Chaos) to see how your app handles the unexpected.
Override presets, failures, and latency directly from a request header for CI, QA, or one-off resilience tests.
