Self-hostable CMS for complex content

What

A self-hostable, MIT-licensed CMS where complex content is first-class — rich text and hand-drawn ScribbleSVG diagrams ship as native field types. AI features are opt-in, including an agent that can manipulate the CMS with the help of tool calls.

Why

I wanted richer content building blocks as native field types, and content that's easier for agents to reach and reshape. Built for this portfolio (blogs coming soon, powered by this CMS itself), then matured into a standalone product.

Technicals

Schema-driven collections with drafts/publish, TipTap rich text + ScribbleSVG diagram fields, Postgres + S3-compatible assets, and an opt-in OpenRouter agent with in-process CMS tools. Docker images on GHCR — self-hosting is a pull and a compose file away.
