Instatic

Design a website on a canvas, manage its content in spreadsheet-style tables, and publish plain HTML, all from one self-hosted Instatic server. Designers see several breakpoint frames side by side, or switch to live mode and edit one full-size page in place. A built-in design system expands one brand color into a full shade scale, generates fluid type and spacing scales, and writes the utility classes into a single small stylesheet. Reusable Visual Components take typed parameters and named slots, templates set site-wide or per-post-type layouts, and loops repeat a design over posts or media. Editors work in custom post types and data tables, and posts move through draft, scheduled, and published states. Forms on the site save their submissions to tables of your own. An AI agent can do the building, placing real, editable nodes on the canvas using Claude, OpenAI, OpenRouter, or Ollama with your own key, and an MCP connector lets Claude, ChatGPT, and other remote agents work on the site too. Super Import converts a whole static site into pages, styles, tokens, and media. Teams get roles built from 38 capabilities, TOTP two-factor sign-in, and an append-only audit log, plus site branches with private copies, shareable preview links, and merge review. Everything published is baked to plain HTML and CSS on disk. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

Benefits

  • Fast pages baked to plain HTML
  • Publishing bakes each page to semantic HTML and compact CSS on disk and swaps it in atomically, so visitors get a file, while a runtime of about 1.1 kB handles per-visitor parts.
  • Design, content, and publishing together
  • The canvas editor, content engine, media library, authentication, forms, and plugins all run inside one server, replacing a stack of separate builder, headless CMS, and form tools.
  • An AI agent that edits pages
  • Describe a change and the built-in agent builds real, editable nodes on the canvas through 35 site tools and 15 content tools, using your own Claude, OpenAI, OpenRouter, or Ollama model.
  • Deploys with one Docker image
  • A single image runs on SQLite or PostgreSQL with optional Caddy for TLS, and backing up the database plus the uploads folder protects the whole site, so updating is just a redeploy.

Features

  • Canvas Editor with Breakpoints
  • Several breakpoint frames sit side by side on one canvas and update together, with a Layers tree and Styles panel, while live mode edits one full-size page in place.
  • Built-In Core Framework Tokens
  • Core Framework generates color shade scales, fluid type scales, and spacing scales from a few inputs, and a utility-class generator writes locked classes into one small framework.css file.
  • Visual Components and Loops
  • Components accept typed parameters (string, number, boolean, color, image, URL, rich text, enum) and named slots, while loops repeat a layout over posts, pages, media, or plugin data sources.
  • AI Agent and MCP Server
  • A built-in agent edits pages and content, and the Streamable HTTP endpoint /_instatic/mcp accepts remote OAuth or personal-token connections from Claude, ChatGPT, and other MCP clients.
  • Data Workspace and Forms
  • Custom post types and data tables take typed fields such as text, number, and repeater, open in a spreadsheet-style grid, and store submissions from site forms.
  • Sandboxed Plugin System
  • Plugins are zip packages with a manifest, and their server code runs in a QuickJS-WASM sandbox with no filesystem or network access unless the owner grants hosts individually.
