Show HN: Intent Bus – SQLite job bus for coordinating scripts across devices
github.comI wanted my PythonAnywhere scrapers to ping my Termux phone when something interesting happened. Every solution I found was overkill — Firebase, Redis, MQTT. So I built a minimal alternative in ~100 lines of Flask.
How it works: - Any script POSTs a job ("intent") to a Flask server - Workers anywhere poll for jobs matching their goal - Atomic SQLite lock prevents race conditions - 60s visibility timeout auto-requeues crashed workers - API key auth
The interesting part is the architecture — workers poll outbound, so they work behind firewalls with no open ports. A Raspberry Pi in your home lab can execute jobs posted from a cloud server with zero Ngrok.
After posting publicly, people stress-tested the open endpoint. Added API key auth and hardened it based on real feedback.

Update: v7 is Live Since the original post, Intent Bus has been hardened significantly based on real-world feedback: - Rate limiting (60 req/min per key+IP) - Tester key system — request a free key to try the live instance - Intent expiry after 24 hours - Python worker for non-bash users - Security headers and payload size limits DM me on Dev.to, open a GitHub Issue, or join the Discord to request a free tester key: https://discord.gg/bzAneAQzGX Update: The Python SDK is officially live on PyPI. pip install intent-bus
