// self-hosted · nothing hard-wired
skela is a deploy platform that runs on your server. every part of it is a plug: where apps run, how they build, where code comes from, who answers dns. keep the built-ins, swap any of them, or write your own. paste a repo and it's live.
click a plug to swap it · dashed ones are extensions you'd write
paste a git url, pick a github repo or a docker image. it's built, it's live at a free url, and every push redeploys. no sidebar, no forty settings pages.

a built-in mcp server with scoped tokens: read or full, every project or a few. your extensions' routes are tools as well, and everything lands in one log.

start-first: a release passes its health check before traffic moves, or the live one keeps serving. rollbacks reuse the image, no rebuild.

skela, its postgres, traefik and your apps run on your server, one box or a swarm. secrets are sealed with a key in /var/lib/skela: back up that folder and one volume, and you have all of it.

skela's core keeps projects, services, deploys and the log. the rest plugs in, and the built-ins use the same sdk you get: replace any of them, limit one to a few projects, or switch it off. drop a folder in your extensions dir and it loads; save a file and it reloads. no restart. pick one below to read its code.
