API Plug: Open-Source API Mocking Tool

API Plug is an open-source API mocking tool that allows developers to create, share, test and validate APIs without having the back-end ready. It provides a simple graphical interface to define APIs and generate mock responses with configurable latency and error conditions.

What is API Plug?

API Plug is an open-source API mocking solution that makes it easy for developers to mock APIs and data models without relying on real back-end services during development. It provides a graphical interface to quickly define endpoints, parameters, responses, and status codes.

Some key features of API Plug:

  • Intuitive graphical interface to define endpoints, params, headers, auth, responses etc.
  • Support for REST, GraphQL, gRPC and WebSocket APIs.
  • Dynamic responses generated based on request data like headers, query params etc.
  • Mock latency, network issues, and status codes.
  • Share mock APIs with other team members.
  • Extend functionality using plugins and webhooks.
  • Integrations with Postman, Insomnia and other developer tools.
  • Self-hosted on-premises or cloud-based.
  • Open source and available free.

By using API Plug, development teams can mock production-like APIs and data without having real services ready. This enables early testing, reduces bottlenecks for front-end/mobile developers waiting on back-end teams, and helps validate APIs before implementation.
