Beeceptor vs MockAPI

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.

MockAPI lets users create REST API endpoints, generate custom data, and operate on it through a RESTful interface. Each project receives a unique base URL shared by its endpoints. Users define resource schemas and field-level generators, including Faker.js functions such as lorem.sentences and datatype.boolean. Relations between resources can be configured, with endpoints generated automatically. Generated resources support GET, POST, PUT, PATCH, and DELETE operations. Listed query capabilities include pagination, sorting, filtering, data generation, and customizable responses, and OpenAPI import is supported. The service is described for prototyping, testing, and learning. Documentation covers projects, resources, data generation, code examples, filtering, pagination, and relations. The Free plan costs nothing for 1 project and 2 resources. Paid monthly access costs $5 a month, and paid annual access costs $35 a year; each paid plan allows 20 projects and 50 resources. Custom endpoints and webhooks are marked coming soon.
