MockAPI vs WireMock

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.

WireMock Cloud provides simulated API environments for software development, testing and AI coding workflows. It supports REST, GraphQL, gRPC, Kafka and SOAP, and can import mocks from Postman, HAR files, OpenAPI or Swagger, and WireMock open source. WireMock Runner can record APIs, including internal services behind a corporate firewall, then run simulations locally or in CI/CD. A remote MCP server and Agent Skills work with named clients including Claude Code, OpenAI Codex, GitHub Copilot, Cursor, VS Code and Augment. The free plan costs nothing and allows one user, three mock APIs, 1,000 calls/month and 10 requests per second, with a limited CLI for local recording. Mocks stop when the monthly call quota is exceeded and resume at the next billing-cycle reset. Enterprise pricing is by tailored quote and includes unlimited calls and team members subject to the license agreement, statefulness, AI features, hybrid deployment, priority support and an SLA. WireMock Cloud is built on the open-source WireMock API mocking platform.
