24 alternatives to I rewrote the 1990's LambdaMOO server
I got my start on the Internet in the very early 90s playing with, authoring in, and programming on LambdaMOO (https://en.wikipedia.org/wiki/LambdaMOO) and similar systems. Shared virtual social spaces, with a persistent object oriented authoring / scripting language. They can be classified as MUDs (depending on who you talk to) but the focus is social, creative / authoring, and shared programming not RPG gaming. I've always wanted to see this kind of thing modernized and further developed. Over the last 25 years or so I've worked on similar but novel & improved…
This is a modernized reimplementation of LambdaMOO, the 1990s virtual social platform built on an object-oriented programming language. It targets creators and programmers interested in shared online spaces focused on… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. I rewrote the 1990's LambdaMOO server launched in 2023; newer entries below may have overtaken it.

Modd.io is a collaborative game editor that runs in browser. It's kind of like Figma for game dev. We made this engine low-code and multiplayer-first, so developeres can quickly prototype casual multiplayer games. I hope some of you guys will find this useful. Would love to hear feedback also. Thank you. Engine Demo: https://www.modd.io

Hey HN, We’re Philip, Amby, and Declan, and we made “multiplayer virtual computers” that you can embed anywhere, including 3D spaces. We decided to build this because we noticed that embedding third-party apps and websites can be a nightmare due to incompatible platforms, security issues, and poor UX. Adding multiplayer functionality to these embeds makes this problem exponentially more difficult. On the backend, we’re spinning up a VM and running a resource-optimized fork of Chromium which we then stream to participants via WebRTC. Since we’re hosting the servers running the applications,…

floors.js▲215Hey HN, I'm Vincent. I built floors.js to bring back social interactions on the web. You paste one script tag. Your pages become isometric 3D rooms. Visitors show up as avatars, see each other, and chat in real-time. Three.js handles the isometric rendering, and a Bun WebSocket server manages presence, rooms and chat. The whole thing runs without touching the host site's DOM or styles beyond its own container. It works on any static site and is also optimised for SPA navigation (clicking on a door lets you navigate to another page). The landing page itself is the live demo, and I'm in the…

Hi HN! During the last few years, I worked on a few applications built with Go, running on AWS Lambda. As I got to know the platform better, I started to find Go & Lambda to be a really productive combination. The applications were fast, and they ended up being much cheaper to run than what my team & I had built before. It’s probably not the best platform for _every_ application, but I was surprised at how much of our workload worked well on it. As we brought new engineers on to our team and helped them get up to speed with the stack, I found that we were covering a lot of the same topics…

I've been presenting at local meetups about Context Engineering, RAG, Skills, etc.. I even have a vbrownbag coming up on LinkedIn about this topic so I figured I would make a basic example that uses bedrock so I can use it in my talks or vbrownbags. Hopefully it's useful.

TLDR: I made a community where you can find builders or product owners to collab on sideprojects together with <3 A year ago i completed my first sideproject, a digital course on how to "cold email a chief information security officer". I thought and think its a great course, but of course I fell into all the traps (didnt verify a need, i thought id make it and everyone would buy automatically), i tested google ads but hated nerding on that, so i decided to find a marketing person to partner up with! But i knew no one! That got me thinking how many people with relevant knowledge that isnt…

Hi HN community! NOTE: This is a repost due to missing of links I’m excited to introduce Lambda, a project I've been working on. Lambda is the world's first open-source social media app designed to prioritize your privacy and well-being. It's still in its early stages, but I'm eager to share it with you and get your feedback. What is Lambda? Lambda is an open-source social media app that addresses privacy concerns and reduces social media addiction. Here's what makes Lambda unique: - Privacy First: Lambda does not collect personal information beyond your email address for account creation.…

Hi HN, I'm one of the engine programmers at All Out Games (https://allout.game/), a multiplayer-first gaming UGC platform where creators can make and play games with their friends. For scripting we wanted our creators to be able to jump in and create game mechanics without having to think about networking. If a developer had to manually send packets to/from client/server to get things to happen then we have failed. It is particularly bad if you are using AI tools because they struggle to keep in mind what code is meant to run where (client, server, or both) and…

Hey HN, A buddy and I have been working on a side project in the online community space in our free time over the past few years. Our platform is a sort of Discord/Reddit/Patreon hybrid. Decided to do a soft launch today in light of all the recent Reddit news. Community features: 1. Customizable discussion boards. Community owners can setup threaded discussion boards for different topics related to their niche. Say a user creates a community for a niche like "Cars", under that community they could create different discussion boards for sub categories like "Car-mods", "Car-photos",…

For the past few months, I’ve been hacking together Hive: a retro-style virtual workspace for devs who love building in public. It’s a bit rough but already has some cool features: - AI-powered presence to represent you when you’re offline. - Live video streaming to showcase your work in real time. - VS Code integration to broadcast your status live. - GraphQL API for full customization and hackability (such as using your own agents) - Web3 donations to support and get support from other builders. In this demo, you can claim a desk by walking up to it and pressing E, then personalize it with…

More than a decade ago, I adopted the self-imposed rule, if I answer a question more than once, the third time I need to be able to answer with a URL. Today, I published one very large URL - a book distilling what I learned from helping people work remotely at GitHub, and I wanted to rethink my rule for the age of AI. What if, instead of a URL, I could create an interactive experience that could tailor the guidance to your particular situation? What I ended up building was an Open and Async Advisor MCP server. To install (in claude or any other AI): > claude mcp add open-async -- npx -y…

I made this as a pair programming exercise with o1-preview. o1 did most of the heavy lifting, through high level prompts, but eventually I needed to diverge from it to get to completion. My initial prompt was: --- I'm making a web app: It's like 4chan, but each thread starts with a gps coordinate. People can only post text and images. I want to build it with flask and sqlalchemy. I want just the backend and data model that supports these threads, anonymous users, and users that can register a permanent username. Write as much of it as you can for me. --- This produced a fully scaffolded…

I recently finished a round of tweaks on my barebones mud-server and thought HN might be interested. https://github.com/endgame/MudCore It sits somewhere between socketmud and a full mud like tbamud in that it handles all the socket work and telnet negotiation, but it makes no assumptions about anything else. The other interesting thing is that it can talk to other services using ZeroMQ. I'm interested in reactions, particularly in terms of coding style, documentation quality and so on. It's my main "presentation piece" so far, in that it's some of the first code I actually feel proud to…

I have always found it funny how challenging it can be to find people to jam on side projects with. There are literally entire sub-Reddits where people post looking for someone to work on a project with. That is super inefficient. There are also newsletters for this (also pretty inefficient). Let's Jam is my attempt to solve this. This is NOT a cofounder matching platform. The idea is to connect people with ideas and skills so they can jam on them together. If they end up becoming cofounders, cool, but that is up to them. This is also NOT a place for freelancers to hunt job opportunities.…

I am a 75-year-old producer. In 2004, I helped bring "Crimson Room" to the global web. After spending 11 years in Fukushima—including 6 years working inside the nuclear power plant—I witnessed firsthand how large organizations can discard individuals. VPP (Virtual Protest Protocol) is my response to the debt-ridden, unequal society we are leaving to the next generation. It is a minimal, sprite-based protocol (MIT License) designed to create high-density, low-bandwidth civic spaces for digital dissent.

Hi HN! I develop Monadic Chat, an open-source framework that connects language models to a Linux environment via Docker. It allows AI agents to execute code, run Jupyter notebooks, and perform web scraping in a secure, sandboxed environment. Key features: - Sandboxed environment for AI code execution - Support for multiple language models - Easy integration with existing Docker workflows I built this because I needed a reliable way to let AI agents interact with a real computing environment while maintaining security and reproducibility. Some possible use cases include: - Helping developers…

I always find myself frustrated by how many steps I have to take to video chat with someone online. There's always too much software to download and install, and too many accounts to remember. The high-end, high-price Cisco conferencing systems I've used are especially fragile. So I built Vidless in a weekend for myself, and I hope you find it useful too. Just create a room and share the link, and you'll be chatting in seconds. You can invite several people (I haven't really tested a max yet), and chats on Vidless are always private. Enjoy!

Hey HN. We've been working on a community platform/Reddit alternative with a focus on building a place for people to create communities instead of just buckets of posts. We want communities to feel like a place where you want to hang out instead of just scroll. At a high level, our platform is like a Reddit/Discord/Patreon hybrid. We took all of the best features from each of those platforms and combined them under one umbrella. Here's a list of the core features of each community: 1. Customizable discussion boards: Community owners can set up threaded discussion boards for…

Hi HN, I’m one of the devs behind StarDesk, a P2P-first remote desktop we’ve been building for ~1 year. We started this partly out of frustration: some popular RDP tools haven’t seen meaningful updates in a long time, and long-standing issues are often left unaddressed. As devs, we really dislike software that stagnates once it “works well enough”. StarDesk is our attempt to do it differently. What we focus on: -P2P by default (relay as fallback) -Low RTT + low jitter > chasing max bitrate -Encoder / input path tuned for real-time interaction -Modern E2EE (TLS/DTLS) UX-wise, setup…

What started as a passion project in 2019, gained a lot of momentum recently. This was possible because of all the contributions and love we got from the community. We’ve created a page (https://contributors.chatwoot.com) to showcase our contributors’ work and give them a platform to share their contributions with the world. We open-sourced this little project too. We’ve made our repo for other open-source projects to use it as a…
