24 alternatives to I made an open-source Replit
I spent the past few weeks making an open source cloud code editing environment with an AI copilot and multiplayer collaboration! It's fully self-hostable in 5-10 minutes. There's a lot of minor improvements to be made, and some are already listed in the Github issues. Let me know what you think and feel free to try it out.
Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. I made an open-source Replit launched in 2024; newer entries below may have overtaken it.

I must say I was encouraged to post my project here when I saw the positive response to this post: http://news.ycombinator.com/item?id=3780731 Before you make any comments, please keep in mind that the project is written for fun. I'm not forcing anyone to use it. In fact, nobody should use the current unstable version in a serious project. Here is the link: http://github.com/bsg/libserv Please share your thoughts. All criticisms are welcome, even the harsh ones. p.s. The project is still a work-in-progress.

It uses claude code with GLM-6 model which is cheap yet powerful for most of the cases. for deployment Cloudflare Workers. It is a 2 weeks of hard work! Lemme know what you think!

I’ve spent the last 2.5 months building a product that runs LLM-powered code reviews on my pull requests — and I just launched it. The tool is built specifically for solo developers. You install it on your repo, trigger a scan by creating a pull request, and it leaves structured review comments using OpenAI under the hood. Funnily enough, I used the dev version of this app to review its own pull requests while building it. It helped me spot bugs, simplify structure, and keep quality high — all with minimal need for another human in the loop. Things I want to try out in the next months : -…

Fully leaned into vibe coding this time around. Started on v0, at some point ejected into running locally (getting v0's exported folder to run locally was a challenge), then iterated with Cursor over the course of a few hours. Really neat how much can be accomplished just conversationally these days.

Hey Hacker News, I'm the maker of Kopage, a free & self-hosted Website Builder. While working on new, cool features (AI, of course), it would be great to hear some HN feedback :) Thanks, Simon

Hi everyone! I've been loving building with AI, and over the past few years I've been leaning more and more into Typescript (and bun). My team at inference.net is constantly trying to get more leverage out of AI and find ways to setup our codebase to be able to increase the level of correctness that our AI is able to write code at. This starter repo is a very opinionated way to lay out a repo to lean into AI heavily. It leverages Cloudflare Workers as a deployment target for the API (my goal is to never have to deploy an API on a AWS/Azure/GCP server ever again unless I get to a…

Try it at: ssh krnl.duetbrowser.com No sign up, totally free - no download. Let me know what you think. Prior art exists (brow.sh) but I wasn't satisfied with their graphical take. I wanted the raw, old skool terminal days of the early internet - BBS, and old green phosphor library comptuers - but running the modern web, with all the bells and jingle jangle whistles (JavaScript, etc). No funding, no VC, just 100% raw terminal fun. Not sure how long the demo will last, but try it out.

Over the past few months, as we scaled our internal AI Agents, we hit a dead end: Running LLM-generated arbitrary code in Docker is basically running naked on security due to container escape risks. But using full traditional VMs takes minutes to boot and eats too much memory to support high-density concurrency. We loved the developer experience of SaaS sandboxes on the market, but they are closed-source, expensive, and have too high a barrier to entry for self-hosting. So, our team decided to build our own. After months of grinding, using RustVMM and KVM, we built a blazing-fast,…

Hey guys, I am think of building an open-source version of Perplexity to let devs play around with it. But with all the existing tools available what features would you want? Anything specific? What is missing? Currently working on - 1. Streaming text 2. Citations sources 3. Image and file upload 4. Chat history and storage 5. Temperature and custom instructions If you are in marketing or growth can anyone help me with what to focus on while building such an app? Also here is a very first version. Probably will break and most of the buttons also don’t work, built it in 3 days using Bing and…

Hi guys, I’m excited to share an update on ReproModel, an open-source toolbox designed to streamline the testing and reproduction of machine learning models. I, like many of you, have really struggled with benchmarking and comparing models, from missing code, to opaque experiment parameters slowing the process. I decided to take matters into my own hands, and created a mini-toolbox in my free time to streamline the process. The goal is to reduce the time and effort spent on replicating experiments, enabling researchers to focus on innovation rather than setup. Knowing this task is not an…

Hi HN! My name is Aymen, and I'm here with Kenichi. Some years ago, I launched a side project. A newsletter called DevOpsLinks, then a 2nd newsletter (Shipped), then a third one (Kaptain). These 3 newsletters are now part of a bigger project that I called FAUN (https://faun.dev). We have newsletters, a Slack team chat, and a job board, but I had a feeling that something is missing... it's a podcast, right :) Last year, I discussed the idea of creating a podcast with a member of FAUN (who is Kenichi btw), but we were not really ready. That's why it took us some months to start…
