Verifiable, not just claimed

"Zero network calls" is a checkable claim, not a marketing line. Here's exactly how it's checked — reproduce it yourself if you don't take our word for it.

Static code audit

Grep the entire source for fetch/XMLHttpRequest/WebSocket and Rust-side network primitives. Only the API Request Tester should match — run on every change.

OS-level firewall block

Block all outbound traffic for the packaged binary at the Windows Firewall and confirm every other tool keeps working fully.

Network-isolated VM

For a stronger guarantee, run the same build with no virtual NIC at all instead of relying on a firewall rule.

verify.sh

$ grep -rn "fetch(" src/
src/pages/ApiTester.tsx  # the one documented exception

$ New-NetFirewallRule \
 -Program airtoolkit.exe -Action Block

✓ every other tool keeps working normally▍

Current status: the static audit above has been run against the full codebase with no unexpected matches. The firewall/VM run is a manual step against a signed release build — not yet performed. Treat any offline claim as unverified until this line is updated.
