Open-source fleet security
Keep watch over every server you run.
Realm Watch builds small, self-hosted tools for people who look after anywhere from a handful to a few hundred Linux servers, often alongside other jobs. They stay quiet until something matters, then tell you what to fix first.
What Realm Watch does
Tools that earn their place on your network
Security tooling for a small fleet tends to be either a spreadsheet or an enterprise platform. Realm Watch sits in between: one honest view of what you run and what needs patching, built so the tool itself never becomes the weak spot.
Self-hosted and small
Runs on infrastructure you control: a single binary and one database file on a $5 VPS. Nothing to subscribe to, and a backup is one file.
Read-only by design
The tools observe and advise. They hold no server credentials and have no way to run commands, so a compromised tool can’t become a compromised fleet.
Open and auditable
Free software under the AGPL, with few dependencies, signed releases and code short enough to read. You shouldn’t have to trust what you can check.
