Open-source alternatives, scored by whether they're actually maintained

49 well-known tools, each with open-source alternatives ranked by a fully published maintenance score computed from live GitHub data — last commit, release recency, stars, open-issue trend. Abandoned projects get flagged, on both sides of the page: several of the "tools" here are themselves dead open-source projects, and their pages say so. Signals fetched 2026-09-04, refreshed weekly.

Most "alternatives" lists never tell you the alternative died in 2021. Every card here shows its maintenance signals and their fetch date, and anything with a year of silence is flagged "looks unmaintained since…" — including the famous tool at the top of the page.
