Docker vs argo-cd
Docker has 72,113 GitHub stars, 19,233 forks, 3,902 open issues and last shipped yesterday. argo-cd has 24,201 stars, 7,859 forks, 4,362 open issues and last shipped today. Docker leads on adoption by 198% (72,113 vs 24,201 stars). Docker is written in Go under Apache-2.0; argo-cd is written in Go under Apache-2.0. Docker has attracted 27% as many forks as stars, argo-cd 32%. argo-cd was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 1 topic tag (docker), so they are genuine substitutes rather than adjacent tools.
Two open source projects, one decision. Both are free and self-hostable — the differences are community size, license terms, language stack and release pace.

pick Docker if
- You weight community size — 72K stars and counting
- You want the Apache-2.0 license terms

pick argo-cd if
- You want the argo-cd feature set and don't need the biggest community
- You prefer the Apache-2.0 license terms
- Your stack matches Go
- You evaluated both and argo-cd fits your workflow better
