Intent Bus - Lightweight Job Queue for Scripts

A minimal job coordination system for distributed scripts that need to communicate across devices without heavy infrastructure. Built as a lightweight Flask + SQLite alternative to Firebase/Redis/MQTT, perfect for developers running scrapers, bots, or automation scripts on multiple machines who need simple task queuing.

The rise of agentic AI workflows and multi-device automation has pushed more developers to coordinate scripts across machines without wanting to spin up Kubernetes or manage a Redis cluster, so the timing is real. The closest substitutes are Redis with a task library like RQ or Celery, and for lighter use cases, CloudAMQP's free tier handles a lot of this already — both are well-understood and widely documented. At $1k–5k/month the revenue math requires either a lot of small-paying developers or a handful of teams, and developers in this niche are historically resistant to paying for infrastructure they can self-host in an afternoon. The most likely failure mode is exactly that: the target user builds their own Flask+SQLite version rather than paying for yours, since the barrier to replication is lower than the barrier to customer acquisition.
