A Mac app that reviews, watches and updates the Linux servers you run yourself, over SSH. Nothing is installed on the servers: it sends a short script, shows what it found, and changes only what you approve. With safe mode on, firewall and SSH changes arm a rollback timer on the server and are kept only once a fresh login works. Built and tested on Ubuntu and Debian.

## What it does

### Review

Scores each server for security and health and lists what to fix first. Read-only: nothing changes until you preview a fix.

### Watch

Outside activity read from the servers' own logs: failed logins, blocked ports, bots and probes, with a one-click block that never touches your own address.

### Update

Patches programs one at a time, checking services, ports and containers before and after, and stops at the first regression.

### Safe mode

Firewall and SSH steps arm a rollback timer on the server, and the change is kept only after a fresh login works. It covers those steps only, not every change.

### AI assistants

Assistants such as Claude Code can read reports and propose changes. You approve every one; they never receive passwords or keys, and they cannot switch safe mode off.

## Guides

The Stenvakt website also carries a library of practical server guides, one problem per page: SSH, firewalls, exposed databases, updates and backups.
