Show HN: Nexus AI – DevOps terminal bridge to Telegram (local-first, BYOK)

I built this because I was tired of SSH'ing from mobile or carrying laptop to cafes just to check logs. Nexus runs as a daemon on localhost, creates a private Telegram bot that only responds to your OWNER_ID, and executes commands locally.

Key tech decisions: - BYOK (Bring Your Own Key): You provide Gemini API key + create your own bot. My operational cost per user = $0 - 3-tier security: Blocked patterns (rm -rf /), dangerous patterns (require confirmation), safe patterns (execute immediately) - Rate limiting: 100 cmd/hour + 2s cooldown + 60s confirmation expiry - Local-first: Code never leaves your machine

$3 lifetime for first 1,000 users. Built with Node.js. Cross-platform binaries.

Happy to answer questions about the security model or architecture.
