In their own words
Beeceptor
Beeceptor is a developer-focused API simulation platform for mocking services, virtualizing them, testing contracts, and simulating failures. It supports HTTP, HTTPS, HTTP/2, mTLS, REST/OpenAPI, SOAP, GraphQL, and gRPC. Users can build no-code mocks with request-matching rules and set response status codes, headers, and bodies. Uploading an OpenAPI specification can create a populated mock server with AI-generated data. Beeceptor can proxy requests to live backends, record traffic, and switch to mock behavior when a backend is unavailable. Latency, timeouts, and errors can be simulated to check client resilience. Its CLI exposes a localhost service through a public HTTPS URL and runs on Windows, macOS, and Linux. Management APIs support mock-server configuration, while MCP connectivity supports AI agents including Claude and Cursor. API Connections store OAuth credentials and generate tokens for outbound requests. Beeceptor says it is SOC 2 Type II audited, adheres to ISO 27001, and complies with GDPR; it also says data is encrypted in transit and at rest. The free plan has public endpoints, a 1 MB request payload limit, and cleanup rules for unclaimed endpoints.
