Simulate APIs, services and agents against any environment — in an isolated sandbox, with built-in APM tracing, and without writing to the real database.
Everything you'd reach for on a support case, a config change, or a tricky debug — in one window.
No server changes, no staging data — point it at a runtime and go.
Add an environment with its Sterling runtime directory and login. Loupe reads the API catalog and config straight from it.
Pick an API, service or agent, give it input, and simulate. It runs in a sandbox — reads are real, writes are captured.
See the response, the SQL, the call tree and timings. Tweak and re-run until you understand it.

The app isn't code-signed yet, so your OS shows a one-time security prompt:
macOS — unzip (double-click the .zip), then open Terminal and run:
xattr -cr ~/Downloads/Loupe.app…then double-click Loupe.app. (One time only.)
Windows — run the .exe and click More info → Run anyway.
No. Each probe runs in an isolated sandbox: reads go to the live system, but writes are captured in a per-probe overlay and journal and never committed to the real database.
No. Loupe runs on your laptop and drives your existing Sterling runtime directory. Nothing is deployed into the OMS server.
macOS (Apple Silicon and Intel) and Windows.
A license is per-seat. Starter covers simulation, sandboxed writes and APM; Professional and Team add the IDE debugger. Your activation enrolls your device; an admin can manage seats and devices at any time. Licenses are delivered securely and verified at startup.
