Beeceptor vs HyperTest

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.

HyperTest describes itself as an AI test engineer for modern backends. Its SDK records requests, responses, database calls, API interactions, execution order, timing, and data flows from actual traffic. When a pull request opens, the service replays baseline traces against feature-branch code, mocks outbound calls, and isolates execution. HyperTest says it reports 5–10 high-signal findings per pull request with traces and reproduction steps. Listed integration-testing uses include APIs, databases, message queues, microservices, and third-party services. It also lists database testing, contract testing, service virtualization, and test data management. Setup connects a GitHub or GitLab repository, adds OpenTelemetry instrumentation, and runs baseline traces once. Supported languages are Node.js and Java. Starter and Enterprise are self-hosted on Linux. Starter is listed at free, with up to 50 services, unlimited test runs, and a 14-day free trial. Enterprise has unlimited services and runs, with price not listed. There is no free plan beyond the listed trial arrangement, and pricing is otherwise on request.
