An independent infrastructure for mail, code, monitoring and the web — containers on a single host, snapshots every night, monitoring that actually pages. No cloud landlord, no tracking you didn't ask for.
Stalwart — IMAP, SMTP, JMAP and Sieve. Full-stack mail, no provider in between.
Forgejo with Actions CI — where this infrastructure's own code lives.
Uptime Kuma — live status of every service, mailbox port and backup heartbeat.
Umami — lightweight, cookie-less web stats for the sites hosted here.
Authelia + lldap — one login in front of the admin surface, OIDC for the rest.
The control panel — service links and operations behind SSO.
Home-energy orchestration on Home Assistant — PV forecasting, battery scheduling and EV charging that follows the sun and spot prices instead of dumb timers.
Registrars compared (Subreg.cz, Dynadot, Cloudflare), DNS via API, nginx vhost, certificate, monitoring and analytics — a new site goes from idea to HTTPS in minutes.
Community and client sites run here too — zmj.cz and ckslavojterezin.cz among them.
