By GitHub stars it is Coolify, with 66,056 stars and a commit on 13 Nov. Choose Coolify when you want a dashboard that deploys apps and databases to cheap VPS boxes, free when you host it yourself. Next come devpush (4,832 stars) and ZaneOps (1,393 stars).

Yes. The code of all 5 is public under Apache 2.0, MIT or AGPL 3.0, so you can use them with no licence fee. Running one yourself costs the server and your time to look after it, and some makers also sell a hosted plan.

Start from the job you use Defang for. Choose devpush when you want Compose apps deployed to Linux servers you already run, from a free MIT dashboard you host. Choose ZaneOps when you want a web dashboard with preview deploys, logs and metrics for apps on a single server you own.

All 5: Coolify, devpush, ZaneOps, Temps and Stormkit. Each tool's page says what it needs to run.

All 5 we track had a commit in the last 30 days, among them Coolify, devpush, ZaneOps and Temps. A recent commit shows the project is kept up, not that it will stay that way.

MIT (3), Apache 2.0 (1), AGPL 3.0 (1). MIT, BSD and Apache let you change and reuse the code freely. GPL and AGPL ask you to share your changes under the same licence when you give the software to others, and AGPL also counts letting people use it over a network.

The hosting. Defang's maker runs the servers for you; with an open source tool the updates, backups, security fixes and support are yours, unless you take the maker's hosted plan. Features differ too, so check what each one imports and exports before you move your data.
