Short answer

OpenGlaze is self-hosted glaze software for potters and studios that want privacy and control. The supported default deployment is a Dockerized Flask app with SQLite volumes for simple, durable self-hosting.

Why it matters

Many potters consider glaze recipes valuable studio knowledge. Self-hosting keeps that knowledge on infrastructure you control.

Private by default

The supported launch path is self-hosted SQLite with Docker volumes, so studio recipes stay under your control.

Computational, not magic

The optimizer uses chemistry calculations and ranked suggestions; kiln tests still confirm real-world results.

How OpenGlaze helps

Clone the repo and copy `.env.example` to `.env`.

Run `docker compose up -d`.

Back up the SQLite and uploads volumes regularly.

FAQ

What database does the supported self-hosted path use?

SQLite in a Docker volume is the supported default today.
