Docker vs goss
Docker has 72,240 GitHub stars, 19,301 forks, 3,902 open issues and last shipped yesterday. goss has 6,001 stars, 504 forks, 57 open issues and last shipped 4 days ago. Docker leads on adoption by 1,104% (72,240 vs 6,001 stars). Docker is written in Go under Apache-2.0; goss is written in Go under Apache-2.0. Docker has attracted 27% as many forks as stars, goss 8%. Docker was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 3 topic tags (docker, go, golang), 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.
