Local-first mock server
Mock APIs locally without losing real data.
Mockphine is a local mock server with passthrough fallback and a live request view, so you can stay fast without drifting from production behavior.

Problem
Mocks drift. Bugs sneak in.
Teams lose time when mocks fall out of sync with real APIs. Debugging becomes guessy, and broken responses slip into production.
Pain points
What slows developers down most
Mocks are stale, so tests pass for the wrong reasons.
Passthrough testing requires swapping tools or configs.
It’s hard to see how a request was actually served.
Solution
Mockphine keeps mocks honest.
Run a local mock server with passthrough fallback. Flip modes per endpoint and watch every request, so you always know what response you shipped.
Why it’s different
Designed around real backend behavior
Fallback mode keeps the real API as the source of truth.
Endpoint modes let you switch behavior without losing data.
Live View makes it obvious when a mock was used.
Workflow
A clear mock loop.
Three steps keep your mocks aligned with reality while you ship fast.
How teams use Mockphine
Simple, predictable, repeatable
1
Create a server with a real backend URL.2
Add endpoints and choose MOCK or PASSTHROUGH per route.3
Start the server and verify traffic in Live View.Key benefits
Confidence without slowing down.
Keep your development loop fast while matching production behavior.
Value you feel daily
Built for real-world teams
Stay honest with passthrough fallback to the real backend.
Switch modes per endpoint without deleting mock data.
Inspect every request with status, timing, and source.
Keep servers and endpoints organized per workspace.
Social proof
Teams ship faster with Mockphine.
Real outcomes from product teams
“Mockphine cut our API test setup time in half while keeping real responses close.”
Lina P., Frontend Lead
“We reduced integration test flakiness by 62% after adopting passthrough fallback.”
Jay M., QA Engineer
“The live request feed made debugging mocks feel instant instead of guesswork.”
Soren K., Full-stack Engineer
