About ossreplace
ossreplace.com is an independent directory of open-source software you can self-host to replace paid SaaS. We aggregate public data — GitHub activity, package downloads, hosting provider pricing, security advisories, Hacker News and Reddit discussions — into one comprehensive page per project.
What makes ossreplace different
- Cost calculator on every page. Other directories tell you a project exists. ossreplace tells you exactly what it costs per month to self-host on Hetzner, DigitalOcean, Vultr, Linode, or Hostinger.
- Composite health score. A 6-dimension score (activity, maturity, community, security, sustainability, adoption) updated every 30 minutes, with the formula and inputs visible on every page. See methodology.
- Real-time community sentiment. Hacker News and Reddit threads from the last year, embedded with vote counts and comment volume.
- Vulnerability tracking. Open security advisories from the OSV.dev database.
- No vendor sponsorship. No SaaS vendor pays for placement. Project rankings are pure data.
How ossreplace makes money
Affiliate links to hosting providers (Hetzner, DigitalOcean, Hostinger, Vultr, Linode) and adjacent paid products. When a reader clicks a hosting affiliate link from a cost-calculator page and signs up, ossreplace earns a commission at no cost to the reader. That commission funds the infrastructure and operating time. The recommendations themselves are based purely on computed cost-of-ownership for each project's actual requirements — no provider can pay for a higher rank. See the full affiliate disclosure.
