## What it is
BlockSuite is a TypeScript toolkit of headless editor frameworks, web components, and editors for building content editing and collaborative applications on the web. It is natively powered by CRDTs (Yjs) for local-first collaboration, conflict resolution, and document streaming.

## Use cases
- build a custom block-based document editor for the web
- add collaborative rich-text editing with CRDT sync to my app
- embed a Notion-style WYSIWYG editor in my web app
- build a whiteboard or canvas graphics editor with rich text
- create framework-agnostic editor components using web components
- implement local-first document editing with offline support

## When to choose
- you need a customizable block editor or canvas editor with built-in collaboration
- you want framework-agnostic web components that interop with React, Vue, etc.
- you are building local-first apps requiring CRDT-based conflict resolution
- you want headless editor infrastructure you can fully restyle and extend

## When to avoid
- you just need a simple drop-in rich text editor with minimal setup
- your project requires a mature ecosystem with extensive third-party plugins
- you need a non-web platform like native mobile or desktop without a web view
- you want a fully managed, batteries-included editor with fixed UI

## Facets
- artifact type: library
- maturity: active
- function: editor, ui-components, state-management, web-framework, templating
- domain: web-development, frontend, text-editors, developer-tools
- platform: browser, cross-platform
- tags: crdt, local-first, collaborative-editing, wysiwyg, web-components, rich-text-editor, block-editor, yjs, notion-style-editor, canvas-editor, real-time, web-server, nodejs
