What is it?

Instatic bundles a visual canvas editor, a content engine, media management, authentication, forms, plugins and a static publisher into a single Bun server that you run on your own infrastructure with SQLite or Postgres. It aims to replace the usual stack of headless CMS, hosting, form service and analytics vendor with one self-hosted application.

The editor is a multi-breakpoint canvas with reusable visual components, templates, loops over collections, and an AI agent that builds editable nodes on the canvas using your own model provider. Core Framework design tokens for color, fluid type and spacing are built in. Forms write submissions into your own data tables, and imports accept raw HTML or whole static sites.

Published pages are semantic HTML and compact CSS with no editor runtime or framework included in the output. Backend plugins run in a per-plugin QuickJS-WASM sandbox whose permissions must be granted by the site owner. The project is at version 0.0.x and the README notes APIs may still change before 1.0.
