Docker vs pytest-testinfra
Docker has 72,113 GitHub stars, 19,233 forks, 3,902 open issues and last shipped yesterday. pytest-testinfra has 2,476 stars, 359 forks, 147 open issues and last shipped 2 months ago. Docker leads on adoption by 2,812% (72,113 vs 2,476 stars). Docker is written in Go under Apache-2.0; pytest-testinfra is written in Python under Apache-2.0. Docker has attracted 27% as many forks as stars, pytest-testinfra 14%. 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.

- You weight community size — 72K stars and counting
- You want the Apache-2.0 license terms
- Your stack matches Go
- You value the larger contributor base for long-term maintenance
pick pytest-testinfra if
- You want the pytest-testinfra feature set and don't need the biggest community
- You prefer the Apache-2.0 license terms
- Your stack matches Python
- You evaluated both and pytest-testinfra fits your workflow better
