Beeceptor is a no-code tool for building stateful mock servers that simulate REST, SOAP, GraphQL, and gRPC APIs for development, testing, and demos.
🚀 Overview
Beeceptor provides an easy way to create realistic mock APIs without coding, enabling independent frontend and testing work.
It solves the key problem of backend unavailability or slowness during development, QA testing, CI/CD, and customer demos by offering instant mock servers from OpenAPI specs, with dynamic, stateful responses, and fault simulation.
Beeceptor is built for developers, QA engineers, and product teams working on API-centric applications. It was created to accelerate development cycles, reduce dependencies, and make API testing reliable and fast.
✨ Key Features
- No Code Mocking: Instantly create mock endpoints via UI or import OpenAPI/Swagger/GraphQL specs, with AI-generated test data.
- Request Inspection: Real-time inspection of HTTP requests, headers, payloads for debugging webhooks and APIs.
- Dynamic & Stateful Responses: Generate responses using request data, maintain state across interactions like real APIs.
- Proxy & Record: Proxy to live backends, record traffic, and fallback to mocks.
- Fault Injection: Simulate delays, timeouts, rate limits, and errors for resilience testing.
- Local Tunnel: Route external payloads to local dev environments. Optional: CRUD support, mTLS, custom domains, API drift detection (paid plans).
🛠 Tech Stack
- Backend: Node.js, event-driven I/O-optimized stack
- Database: Schema-less storage for stateful CRUD
- Frontend: Modern JavaScript framework (React inferred from UI)
- Hosting: Cloud infrastructure (99.9% uptime)
👥 Who Is This For?
This project is useful for:
- Developers who want to mock APIs quickly without coding or databases
