Sentry vs logbook
Sentry has 44,806 GitHub stars, 4,857 forks, 2,265 open issues and last shipped today. logbook has 2,065 stars, 288 forks, 26 open issues and last shipped 2 days ago. Sentry leads on adoption by 2,070% (44,806 vs 2,065 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.
