10 Best GitHub Repos for Security & Privacy in 2025


GitHub hosts thousands of open-source projects, but finding the best ones for security takes hours of research. We've done the work for you — here are the top projects worth deploying on your own server.


Why Self-Host GitHub Projects?


Open-source software gives you the code, but running it requires infrastructure. Self-hosting means:


  • **Full data ownership** — your data never leaves your server
  • **No SaaS fees** — pay only for the server ($5/month on TinyPod)
  • **Unlimited users** — no per-seat pricing
  • **Customization** — modify configs, themes, and integrations freely
