Why Choose MockQL?

The only API mocking solution that works with your existing backend instead of replacing it

Transparent API Proxy

Extend your existing backend without any changes

MockQL acts as a transparent proxy between your frontend and backend. It passes through all existing API calls unchanged while allowing you to extend or modify specific endpoints.

mockql.config.js
// Original API endpoint working as normal
fetch('https://mockql.com/api/proxy/project-id/api/users');

// New endpoint that doesn't exist in your backend yet
fetch('https://mockql.com/api/proxy/project-id/api/comments');

Key Benefits

  • No backend changes required
  • Use production data with mock extensions
  • Gradual transition to new API features

How MockQL Compares

See why developers choose MockQL over traditional mocking solutions

Traditional Mocking

Separate mock servers that replace your real backend

  • Requires switching between environments
  • No access to real backend data
  • Separate URLs for development vs. production

MockQL Approach

Transparent proxy that enhances your existing backend

  • Use the same URL for mock and real data
  • Combine real backend with mock extensions
  • Gradually transition as backend evolves

Custom Mock Code

Writing and maintaining custom mock implementations

  • Time-consuming to build and maintain
  • Code diverges from actual implementation
  • Difficult to share across team members

Popular Use Cases

See how teams are using MockQL to accelerate development

Frontend Development

Build UIs without waiting for backend APIs to be ready. Work independent of the backend team's timeline.

API Testing

Simulate edge cases, errors, and response variations to ensure your application handles all scenarios gracefully.

Prototyping

Quickly test new API designs and get feedback before investing in full backend implementation.

Schema Evolution

Test GraphQL schema changes gradually without breaking existing clients or requiring full backend updates.

Error Handling

Verify your application's resilience by simulating various error responses, timeouts, and edge cases.

Team Collaboration

Share consistent API mocks across frontend, backend, and QA teams to ensure everyone works with the same expectations.
