Coffey LabsWhat we make
Each product has its own site, docs and community. Every one is open source, runs on your own hardware and has no paid tier.

Smaller things we maintain
Tools that started as one-off jobs on our own servers and turned out to be worth keeping.
-
stalwart-migrator (opens in a new tab)In-place Stalwart upgrades
Takes a Stalwart mail server from 0.15.5 to current without data loss, checkpointing every step so an interrupted run resumes rather than restarts.
-
ihasmail-oneshot (opens in a new tab)Stalwart and ihasmail in one command
Turns a fresh Docker host into a mail server with webmail: certificates, the first mailboxes and the DNS records to publish, left behind as an ordinary compose project.
-
SysAdminAutomation (opens in a new tab)Bash for the jobs that recur
Distribution-agnostic scripts for backups, logs, monitoring, users and updates. Everything destructive takes --dry-run, and with no terminal to ask on it refuses rather than guessing.
