I Run My AI Assistant 24/7 on a $0 Server. Here's Every Detail.

My AI assistant doesn't sleep. It checks my calendar every 3 hours, summarizes my day at 9 PM, reviews my GitHub repos every 2 hours, and syncs notes to Notion at 10 PM. All on its own. The server costs me $0/month. Not "$0 for the first year." Not "$0 with credits." Actually zero, forever. Here's the full setup — including the mistakes I made so you won't have to. TL;DR: You can run a Claude-powered Telegram bot with 9 scheduled jobs 24/7 on Oracle Cloud's Always Free tier — $0/month, no expiration. The hardware: 1 OCPU + 1 GB RAM + 4 GB swap. After 2 weeks of operation: 99.7% uptime, 3 auto-recovered OOM events, ~15 scheduled job executions per day. Key tricks: aggressive swap, flock-based concurrency control, systemd auto-restart, and 5-minute health monitoring via cron. The Problem: AI Assistants Die When You Close Your Laptop I built a Telegram bot powered by Claude. It worked great — when my MacBook was open. Close the lid? Silent. Morning briefings? Missed. Calendar reminders? G
