api client · built for flow state
Type, send, drag,
send again.
One input. Sends materialize as sheets you can stack, dismiss, and bring back. No tab-switching, no sidebars, no dropdowns mid-typing — just an API client that respects your rhythm.

01
The sheet is the response
Hit Enter and the result materializes as a draggable sheet with physics. Drag it down to dismiss, drag it back to revisit. Cards aren't tabs — they're objects.
02
History is ambient
The last few requests sit visibly above the drawer as a peek rail. Click any to re-open. You see what you tested 30 seconds ago without leaving the surface.
03
Workspaces, not tabs
Partition contexts (dev, staging, prod) into colored workspaces. Each carries its own draft and its own rail — switch with one click, no env-toggle anxiety.
Drift detection on every re-test.
Hit the same endpoint again, see exactly what changed: status, shape, size. A free regression check, every time.
