Craftplan – Elixir-based micro-ERP for small-scale manufacturers
My wife was planning to open a micro-bakery and we started looking at software to manage recipes, inventory, orders, and production. Everything was either expensive, too generic, or both. The workflows for a small-batch manufacturer aren’t that complex, but the pricing acts like they are. So I built Craftplan. All the features were tailored to what she actually needed, and I figured other small-scale manufacturers (soap makers, breweries, candle makers, etc.) probably need the same things. So I’m putting it out there for free. - Live demo: https://craftplan.fly.dev ([email protected]…
In plain words
Craftplan is a free, Elixir-based micro-ERP designed for small-scale manufacturers like bakeries, soap makers, breweries, and candle makers. It streamlines recipe management, inventory tracking, order handling, and production planning without the complexity or cost of generic enterprise software. Built to match the actual workflows of small-batch producers, Craftplan offers essential features in a straightforward interface and is available for both cloud use and self-hosting.

The DSL makes it simple to translate your thinking into live product - Extensibility: With Ash + LiveView you can add more features so easily. Adding JSON:API + Grapghql was a few minutes. - UX: I believe LiveView makes it simple to deliver great UX since it forcing you to keep things simple with no so much interaction overhead which most of the time means better and simple experience Self-hosting: - Docker image: `ghcr.io/puemos/craftplan` (amd64 + arm64) - Docker Compose bundles PostgreSQL 16 + MinIO. Other details: - Email config from UI (SMTP, SendGrid, Mailgun, Postmark, Brevo, Amazon SES) - API keys encrypted at rest (AES-256-GCM) - Role-based access (admin/staff) - Tech stack: Elixir, Ash Framework, Phoenix LiveView, PostgreSQL - License: AGPLv3 Feedback welcome (and needed!)
