- Established, but community shifted to LibreNMS
The catch
The free Community edition lags badly — 6-monthly tarball releases while Pro moves fast — so security/feature parity requires paying, which is exactly why many migrated to its fork, LibreNMS.

The honest take
The original “just autodiscover everything” tool — but the free edition has drifted so far behind Pro that most people just run LibreNMS now. Included for completeness and history.
