Show HN: BlockNote – open-source Notion-style Text Editor with Multiplayer

Hi HN! BlockNote is an extensible, block-based editor (similar to Notion, Coda, etc.). Featuring different block types, animations (try changing block types, indenting, etc), menus, placeholders, collaboration and more you expect from a good editor.

BlockNote builds on top of Prosemirror and TipTap (two great libraries to build text editors for the web and work with ContentEditable and its quirks), but these libraries are pretty bare-bones / low-level("headless").

I hope BlockNote makes it a lot easier to get a great out-of-the-box text editing UX and am looking forward to your feedback!

I just added real-time collaboration to the demo on the homepage (desktop only), powered by Yjs & Partykit - definitely play around :)
