Self-host a lightweight ERP for small craft businesses with Craftplan

Craftplan is worth bookmarking if you help small makers, bakeries, food producers, or other craft businesses escape spreadsheet-driven operations without buying a full enterprise ERP. The project is open source under AGPL-3.0 and is built around small-batch, made-to-order workflows instead of generic inventory tables.

The practical value is the breadth: versioned bills of materials with cost rollups, order scheduling, production batches, raw-material inventory, lot traceability, allergen and nutrition tracking, purchase orders, customer/supplier records, CSV import/export, iCal feeds, and JSON:API plus GraphQL endpoints. That makes it useful both as deployable software and as a reference implementation for vertical SaaS builders.

Caveats: it is self-hosted, so expect Docker/server administration, secrets setup, backups, and operational ownership. The latest GitHub release checked for this Loot is v0.5.0 from June 23, 2026, so treat it as promising open-source infrastructure rather than a mature turnkey SaaS.
