Key Principles¶

✅ Open source first — Every app is free and open source software
🔒 Self-hosted — No third-party cloud dependencies for core services
⚡ Automation — Cron jobs handle backups, updates, monitoring
🔄 Redundancy — Docker volumes backed up daily, Syncthing mirrors critical data
🛡️ Cloudflare — DNS, CDN, DDoS protection, and tunnel for secure access
