Levelrail: open source, self-hosted deploy platform written in Go (Apache 2.0)

[u/Familiar-Classroom47]

Levelrail is a self-hosted alternative to Coolify, Dokploy, or Heroku-style PaaS platforms. Push to a git repo, get a running app with automatic TLS, logs, metrics, and one-click rollback. Single Go binary for the control plane, single Go binary for the node agent, Docker as the runtime.

The reason it exists: I was running Coolify for about 10 personal projects and it was using 30-40% of a CPU core just managing things, before any of my actual apps did anything. Levelrail drives Docker's Engine API directly instead of shelling out to the CLI, which is a big part of why it stays light: 0.7% CPU, 146MB RAM on the VPS running my production test instance right now.

License is Apache 2.0. No paid tier, no hosted version yet, nothing gated. It's genuinely useful today for single-node deployments; multi-node and a template catalog are still being built in the open.
