  • ZeroNet

    ZeroNet - Decentralized websites using Bitcoin crypto and BitTorrent network

    Project mention: Professor of law, Bruce Pardy on Trudeau's upcoming internet censorship in 2023. | | 2023-01-11

    Nothing can be censored here. Nothing. read that again. Nothing can be censored because it is 100% decentralized, that is the opposite of centralized power.

  • gun

    Project mention: Meet OctoBase - AFFiNE's local-first, collaborative open-source database! | | 2023-01-31
  • Appwrite

  • yjs

    Shared data types for building collaborative software

    Project mention: Hindsight is a free and open-source retrospective board | | 2023-01-07

    No back-end. Data is shared via WebRTC directly between connected browsers. I'm using Yjs to help me with that.

  • HackMD

    CodiMD - Realtime collaborative markdown notes on all platforms.

    Project mention: Ask HN: Ways to make Git easier for non-tech folk? | | 2022-09-27

    Honestly, it might be better to use a realtime collaboration service. If you need to you could automatically sync this with the GitHub version by pulling updates on a schedule.

    I've used for real-time collaboration in Markdown. They even offer an open-source self-hosted version, There may be other services as well.

  • SocketCluster

    Highly scalable realtime pub/sub and RPC framework

    Project mention: On the Unhappiness of Software Developers | | 2022-09-03

    This resonates with me 100%. Every bit of unhappiness I've felt in my career so far has been caused by a bad manager. The main issue for me has been the final point you mentioned about "Imposed artificial limitations" - I cannot tell you the number of times that I've been forced to use an inefficient tool or do something in a sub-optimal or downright incorrect way (knowing that it would have to be re-written later) by a bad manager... In some companies, it was a daily occurrence; that's why I never stayed at a single company for longer than 2 years. It's almost impossible to find a company that lets me implement things correctly.

    Thankfully, nobody could constrain me in my open source work. I (with the help of community members) built:

    - SocketCluster ( A distributed pub/sub framework.

    - Capitalisk ( A lightweight quantum-resistant blockchain which is less than 5K lines of code.

    - LDEX ( A deterministic decentralized exchange (DEX) which can work with many different blockchain protocols. It's less than 4K lines of code in total and only has 3 small third-party dependencies (including sub-dependencies).

  • trystero

    🤝 Serverless WebRTC matchmaking for painless P2P — Make any site multiplayer in a few lines — Use BitTorrent, IPFS, or Firebase

    Project mention: UnCloud project: WebRTC chat, file transfer, and remote observation | | 2022-12-18

    Yes, this is a major issue that I haven't found a real solution for. There seems to be a mixture of iOS Safari bugs and intentional design limitations at play, and I don't know if a fully P2P web app like Chitchatter is practical on that platform. There's an open issue to improve this in Trystero (the networking library that Chitchatter uses), but there may be a limit to how stable iOS will be with WebRTC apps. 😕

  • chartjs-plugin-streaming

    Project mention: Ask HN: What is something you built but never marketed? | | 2022-08-14

    A data-synchronization library for Node.js

    Ever get tired of sending API requests and JSON payloads? Wouldn't it be cool if data just synced between server and client?

    Jsynchronous lets you share deeply nested object/arrays between node.js and connected browsers – and any changes made to that variable.
