Interactive demo
Flip API states. Watch the app follow.
This is a real FlowMock proxy session with sample apps on the other side. Pick a scenario, use the app, and see every request FlowMock changed - no install, no account required.
Every request below is yours. Flip a scenario, use the app, and see exactly what FlowMock changed.
What you are looking at
FlowMock sits between your app and staging. By default traffic passes through unchanged - until you activate a scenario that overrides specific responses for your session only.
Scenarios on the left
Each pill is an API state your team might need: empty cart, declined card, slow shipping, server error. Activate one and only your session sees it.
Traffic in the middle
Every proxied call appears here with method, path, status, and timing. This is the same request log your team uses in the dashboard during real QA.
Demo apps on the right
Real frontends talking to the proxy - not a video. Refresh after flipping a scenario and the UI reflects the new backend state immediately.
In your project you point your app’s API base URL at FlowMock once. The whole team shares one proxy URL; each tester’s session stays isolated.
