We run os-alt , a directory of paid SaaS and the open-source tools you can self-host instead. Once a month we re-run a build-time freshness check on every recommended GitHub repo we list. The first four monthly posts in this series sorted projects one vertical at a time (PagerDuty alts, link-in-bio, Datadog, license-drama). This is the first one that zooms out across the whole corpus.

The full report — with sortable tables, methodology, citation-ready JSON-LD, and re-derivable numbers from /api/health.json — lives at the canonical URL . This dev.to write-up is the readable summary.
