BlockNote – a “Notion-style” block-based text editor
Hi HN! BlockNote (demo @ https://blocknote-main.vercel.app) is my shot at creating 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. I'm on a journey to build a decentralized, live-programmeable and collaborative block-based editor [1] that syncs over Matrix [2], and unfortunately found that there's still not a great Open Source text editor component on par with something Notion's editor, which is why I…
In plain words
BlockNote is an open-source, block-based text editor for web applications, similar to Notion or Coda. It supports multiple block types, animations, menus, and placeholders, built on Prosemirror and TipTap. The editor is designed for developers building extensible content editing tools and includes collaboration features. The creator is working toward a decentralized version that syncs over Matrix protocol.

Hi HN! BlockNote (demo @ https://blocknote-main.vercel.app) is my shot at creating an extensible, block-based editor (similar to Notion, Coda, etc.).

I'm on a journey to build a decentralized, live-programmeable and collaborative block-based editor [1] that syncs over Matrix [2], and unfortunately found that there's still not a great Open Source text editor component on par with something Notion's editor, which is why I got started with this. BlockNote builds on top of Prosemirror [3] and TipTap [4] (two great libraries to build text editors for the web / work with ContentEditable and its quirks), but these libraries are pretty bare-bones ("headless"). While there's still some ground to cover, I hope BlockNote makes it easier to get a better out-of-the-box UX and am looking forward to your feedback!

A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc. The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly. This model can be used to disrupt any marketplace from AirBNB to UberEats: building tech for home renters and restaurants and later, leveraging that to build a competing…
