Show HN: Bus Core – a local-first ERP for small manufacturing shops
True-Good-Craft Thursday, March 05, 2026I built BUS Core, a local-first ERP aimed at small manufacturing shops and makers.
It handles inventory, vendors, manufacturing runs, and costing.
Everything runs locally: - no accounts - no telemetry - no SaaS dependency
The goal was to make something usable for very small shops that outgrow spreadsheets but don't fit traditional ERP systems.
Tech stack is intentionally simple: Python backend + SQLite + local web UI.
Project started as an experiment in building software using LLMs with a strict Source-of-Truth + smoke test loop.

Curious to hear from anyone running small production operations — what breaks first as you scale past spreadsheets?
