Why do people use MockLab?

Stay productive when an API you depend on doesn't exist
or isn't complete.

Test edge cases and failure modes that the real API won't reliably produce.

Diagnose problems faster and find root causes quickly through the visual request log. 

Super-fast hosted mocks, with a QA-friendly UI.

Simulate stateful behaviour in your mocked API using a simple finite state machine model.

Response templating

Dynamically render responses using the Handlebars templating language.

Manual and automated testing

Craft your simulation using the friendly, no-code UI or go fully automated with the 100% WireMock-compatible API.

Capture traffic to another API, then play it back from MockLab.

Record and playback

Conditional proxying

Mock the unfinished parts of the API and proxy the rest straight through to the real thing.

Test your app to destruction by injecting delays, dropped connections, drip-drip responses and corrupt HTTP payloads.

Delays and faults

All the power and flexibility you need for pain-free testing
