OpenCauldron is built in public on a Next.js + Postgres + R2 stack. Add a model, fix a bug, ship a feature — your contribution stays open under the Sustainable Use License.
Concrete areas where new contributors land impact quickly. Pick one that matches your interest.
Wire in another model API — image, video, audio. The provider registry makes it a focused, well-scoped PR.
Polish flows, expand the asset library, build dashboards. Next.js + Tailwind v4, no framework guessing required.
Help shape brand kits, prompt templates, and campaign tracking — the workspace primitives creatives actually use.
Docker, Postgres, R2, auth. Make the install path more bulletproof for users who run their own.

OpenCauldron uses the Sustainable Use License — the same license n8n uses. Source is open. Code is auditable. You can fork, modify, redistribute, and self-host freely for any internal business or personal use.
The one thing the license prevents is third parties selling OpenCauldron as a commercial service that competes with us. That’s what keeps the project sustainable while staying open to almost everyone who wants to use, learn from, or improve it.
Your contributions stay under this same license. By submitting a pull request, you agree your work joins the project under the same terms — same protection, same openness.
Four steps. Each one well-trodden by previous contributors.
Star the repo to follow releases. Clone, run docker compose up, and the studio is running locally in a few minutes.
Filter for the good-first-issue label. Each one is scoped, documented, and reviewed end-to-end.
Push your branch as a draft when you're getting started. Easier to iterate on direction than to redo it at the end.
Tests pass, reviewers approve, your name joins the contributors list. Pick the next one.
OpenCauldron is built in the open. Star us on GitHub, join the Discord, or dive into the code and contribute.
