Sentry has 45,704 GitHub stars, 4,959 forks, 2,265 open issues and last shipped yesterday. zabbix-docker has 2,857 stars, 1,435 forks, 7 open issues and last shipped 2 days ago. Sentry leads on adoption by 1,500% (45,704 vs 2,857 stars). Sentry is written in Python under a custom or non-standard licence; zabbix-docker is written in Dockerfile under AGPL-3.0. Sentry has attracted 11% as many forks as stars, zabbix-docker 50%. Sentry was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 1 topic tag (monitoring), 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.
