24 alternatives to Hocuspocus 4 – self-hosted Yjs collaboration backend
Hi HN! I'm Philip, one of the founders of Tiptap. Next to our open-source rich text editor framework, we started developing Hocuspocus about five years ago and open-sourced it too, to solve one of our biggest challenges back then: real-time collaboration in web editors. We found Yjs by Kevin Jahns, a CRDT library that handles concurrent edits without conflicts. Basically, Yjs merges changes from users without conflicts and in real-time. Hocuspocus is the WebSocket server built on top of Yjs. It handles real-time sync, presence/awareness, persistence, and Redis-based scaling. While we…

Inspired by the design and UI/UX of apps like Notion, and utility of open-source apps like StackEdit, I decided to create a minimalistic, local-only WYSIWYG Markdown editor. Some features worth highlighting: - Monaco editor and Prettier integration for code snippets - Tables (apparently the holy grail of WYSIWYG editing) - Embeds (for CodePen, CodeSandbox and YouTube, most useful for HTML or JSON exports) - Accepts Markdown paste-in, and "exports"/generates HTML, Markdown and JSON outputs - Collaboration (with real-time awareness and initial commenting system, available only when…

Show HN: Tiptap Editor 3.0 Beta is out. Hi HN! Philip here from Tiptap (https://tiptap.dev/). We're excited to announce Tiptap 3.0 Beta, a major upgrade built with and for the open source community. It's still extension-based, still unopinionated, but we've tackled some of the biggest developer headaches: Enhanced TypeScript support: Strong typing for extension storage and config options. Server-side compatibility: Manipulate editor content on the server, no DOM required. JSX support: Leverage a modern, React/Vue-like approach to describing your node output. Expanded…

Hi HN! Matrix-CRDT connects the worlds of Yjs [1] (a proven, high performance CRDT) with that of Matrix.org [2]. It started as an experiment, asking myself; can we store "state updates of a datastore" in Matrix instead of chat messages? Now, I'm convinced it's actually a really powerful combination to develop real-time, collaborative software. I'm using it for a new project and so far didn't have to write a backend yet. Matrix takes care of a lot of stuff: Authentication, E2EE, federation, hosting, etc. - so I can focus on the client. I love the ideas of Local First [3] software. Personally,…

I've always been curious about real-time multiplayer user interfaces. When I found out about CRDTs and Yjs[1] I thought they could serve as a solid base for a project like that. So I built this pretty simple desktop-like UI (heavily inspired by lifeat.io) and used Yjs to replicate the whole UI state among multiple peers, creating the experience of a unique interface.

Hey HN! I’ve written a bunch of WebSocket servers over the years to do simple things like state synchronization, WebRTC signaling, and notifying a client when a backend job was run. I realized that if I had a simple way to create a private, temporary, mini-redis that the client could talk to directly, it would save a lot of time. So we created DriftDB. In addition to the open source server that you can run yourself, we also provide https://jamsocket.live where you can use an instance we host on Cloudflare’s edge (~13ms round trip latency from my home in NY). You may have seen my…

Hi HN! My name is Nick and this is my fun side project. Please lay it on me. HN can think of Tips.io as a cracked out Tailwind Playground that has page management and amazing AI integration. There are a few core ideas: 1) The HTML is the CMS There are no fields or restrictions. Just hover, click, and start tweaking any HTML. Also, certain elements you click will have special easy edit abilities: - auto creates an uploader, stock photo picker (or HTML) - auto creates an uploader, stock video picker (or HTML) - auto creates a big icon picker (or HTML) - auto creates a WYSIWYG Editor (or HTML)…

This is an experimental extension for CRDTs, pg_crdt: GitHub repo[0]. It supports Yjs/Yrs and Automerge. The linked blog post [1] describes how we're thinking about this extension in a Supabase context. I want to emphasise this part: "pg_crdt has not been released onto the Supabase platform (and it may never be). We’re considering many options for offline-sync/support and, while CRDTs will undoubtedly factor in, we’re not sure if this is the right approach."

Hey HN, I'm Hakan, the founder of Colanode (https://github.com/colanode/colanode), an open-source, local-first collaboration app combining the best of Slack-style chats and Notion-style note-taking, fully self-hostable for complete data control. Here's a quick demo: https://www.youtube.com/watch?v=wp1hoSCEArg As a heavy Notion user, I often found it tough to get my teams fully onboard since people naturally gravitate toward chat for quick interactions. Maintaining context between chat apps like Slack and documentation apps like Notion became increasingly…
