Docker vs argo-cd
Docker has 72,240 GitHub stars, 19,301 forks, 3,902 open issues and last shipped yesterday. argo-cd has 24,541 stars, 8,093 forks, 4,362 open issues and last shipped yesterday. Docker leads on adoption by 194% (72,240 vs 24,541 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 33%. Docker 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.
