In their own words
Mockzilla
Mockzilla turns OpenAPI specifications or plain JSON files into hosted mock APIs for frontend work, integration tests, and demos. It generates responses from OpenAPI schemas and can validate requests against the specification. Users can inject latency or errors at service or endpoint level to exercise retry and fallback behavior. A proxy can forward requests to a real backend while supplying mock responses for routes that backend does not serve. Its GitHub Action creates a mock URL for each pull request, updates it on pushes, and cleans it up when the branch is gone. Mockzilla records request status and timing, and supports replaying individual requests or sets of requests. The CLI is MIT-licensed, works offline, and can run on a laptop or in CI; hosted cloud features are optional. The site also lists a GitHub Action and MCP server, with CLI setup instructions for Claude and Gemini. The Free plan is free, but API access is unavailable and request history lasts two hours. Hobby costs $10 a month. Uploaded content must not contain personally identifiable information, real financial data, health records, credentials, or other sensitive data.
WireMock
WireMock simulates APIs and software dependencies so teams can test without live services, exercise edge cases, and build dependent features in parallel. It can match requests using URL patterns, headers, query parameters, cookies, and body content, then return templated responses or simulate delays, network faults, and malformed replies. It can also record interactions with real services and replay them during tests.
The project integrates with JUnit and other testing frameworks, with setup paths for Maven, Gradle, Scala SBT, standalone use, and Docker. Its documented capabilities cover HTTP-based protocols and REST, plus WebSockets, webhooks, HTTPS, gRPC, and GraphQL. WireMock Java is available as a standalone JAR, Docker image, experimental Helm chart, and NPM package; WireMock Cloud is another option. The Free plan costs nothing and includes 1,000 calls per month, one user, three mock APIs, and a 10 requests-per-second limit. Free and trial plans stop running mocks after their API quota is exceeded until the next quota cycle.
