FlowGuardInspect apps and destinations
Observe established TCP connections every five seconds. Follow destinations by app, then search and filter the connections you need.Visibility depends on the current user’s permissions.
FLOWGUARD / NETWORK OBSERVATORY
See where yourMac connects.
Which app connects where? FlowGuard brings Mac connection observation, LAN device inspection and server response checks into one network management app.

01 / WORKSPACE
From app connections to your network.
Organize connection rules
Save allow, block and ask intentions. Import and export JSON, inspect session history, and dock or float connection details.Saved intentions are distinct from OS application status.
Inspect LAN devices and ports
Inspect LAN information and manually check TCP ports on a selected device. Compare results and export CSV records.IPv4 / IPv6 supported; some real LAN validation remains pending.
Check server responses
Check HTTP, HTTPS, SSH and SMTP responses. Port-based candidates are shown separately from services confirmed by a response.Response checks do not certify security or internal service health.

Development status
Implemented features and upcoming work, with validation limits made explicit.

03 / FIELD NOTES
Good to know
Where is data stored?
Rules and settings are stored in the Mac app data directory. Connection history stays in session memory. JSON backups include executable paths and destinations.
Are observed connections safe?
Observation is not a safety verdict. Domain, country, traffic volume and TLS content are not inferred. Socket observation alone cannot determine which side initiated a connection.
Which languages are available?
The app supports English, Japanese and Simplified Chinese. It is being developed for macOS with Tauri 2 and Rust.
