Sentry has 45,704 GitHub stars, 4,959 forks, 2,265 open issues and last shipped yesterday. logbook has 2,071 stars, 290 forks, 26 open issues and last shipped 2 days ago. Sentry leads on adoption by 2,107% (45,704 vs 2,071 stars). Sentry is written in Python under a custom or non-standard licence; logbook is written in Java under MIT. Sentry has attracted 11% as many forks as stars, logbook 14%. 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.
