Murmell
Hey HN! I'm Moss'Ab. Murmell (https://murmell.com) is an infinite canvas where coding agents run together in the cloud instead of on your laptop. It's like Google Docs, except the other editors are you, your teammates, and a set of agents all working in the same canvas. Short demo: https://app.murmell.com/demo The idea came out of a YC hackathon. We were trying to build the thing under extrem pressure, deploying at the very last minute, but with several agents working in parallel, all the branches collided. Everything broke at the worst possible moment and we spent the end of it untangling instead of building. We didn't win. Murmell is the thing I wished we'd had that day: one place where the agents and the people can see each other work, on machines that don't belong to any one laptop. Each canvas gets its own machine in the cloud. Close your laptop and the agents keep going; open it again anywhere, or have a teammate open the same canvas by sending him the link, and you're inside the same session rather than a copy of it. The work stays exactly where you left it : same branches, same dev server still running, so an agent picks up mid-task instead of starting from scratch. And you can literally collaborate with your team like google docs, it's se same system, read of edit link, they connect they can type on your terminal, you can see their mouse, wich terminal they're typing in. And you can interact wich each other sessions, it's pretty useful instead of sharing a screen, copying a prompt, etc. The hardest part was building the cloud infrastructure, trying to make it scalable, and to manage the sessions to make the best experience possible: when the VM shuts down, it snapshots everything and restores everything when you come back, even the conversation with your terminal, it's stored with a system that i built like obsidian wich also make you save a little bit of tokens. So the answer to that hackathon is file claiming. Before an agent works on something, it claims the paths, it's an exclusive lease with a TTL, so nothing stays locked forever because an agent died mid-task. And if another agent asking for the same file gets denied, the denial tells it who holds it, how long is left, and to either pick other work in its scope or message the holder (the agents can communicate through the board) A watcher classifies every write, so if anything writes inside someone else's claim it shows up on the canvas as a collision right then, instead of as a merge conflict you discover an hour later. And when an agent is done, it can hand its claim to the next one. And agents never hold your provider keys either, they get a token, and a proxy on the container's loopback swaps it for the real key on the way out, which makes a leaked token worthless outside that container. Murmell is paid. I've put prices at 50% off for now, because it's still not where I want to take it yet. It is fully usable though: I develop Murmell with Murmell, every day (and tbh it's save soooo much time to us with my cofounder) And to be fully transparent with the actual prices it costs us much than we are earning but the goal is to collect feedback to make Murmell as good as possible For context: I'm 19, a 4th year computer engineering student, and I've been on this for about three and a half months, day and night. I discovered claude code after my father showed me first Windsurf (today Devin) for a python homework in 2024, and i think i never went somewhere without my laptop since then lol. So feel free to comment or to give feedback, or even subscribe to support the project :)

I have been working on Sesame, an open-source password manager that keeps your vault local by default. You don't need an account to create or use a vault, and the hosted service never receives the vault itself. It's still early software and the independent security review isn't finished yet, so I am mainly interested in feedback, testing, and people looking through the code. (Linux support is yet to be released on v0.1.2, but currently is in the works.)

I've been learning Japanese for a few years and kept running into a similar problem. I'd find a video I wanted to learn from, hear a useful sentence, and then realise that turning that sentence into something I could study later was both time consuming and draining at times. I would end up jumping between a video player, subtitles/transcription, a dictionary, screenshots, audio clips and Anki. So I built SubSmith to bring that workflow together. You can drop a video or audio file into it, generate a transcript locally and then use the transcript alongside the media to: * look up words and sentences * replay individual lines * edit the transcript * save useful sentences with their original context/audio * export them as Anki cards The important part for me is that it works with your own media. It isn't tied to a particular streaming service or library, so I can use the random anime episode, podcast, lecture, etc. that I'm actually interested in studying. It's an offline-first desktop app, and transcription happens locally rather than sending the media to a transcription API. I'm sharing it here because I'm now more interested in finding out where this workflow breaks down for other people rather than adding features randomly now that I have solid core/base. For example: * Would you actually save sentences from your own media? * Which part of this process feels like too much work? * Does having the audio/context attached make creating an Anki card more useful? * Would you prefer this to work inside your existing video player/browser? * Is installing a desktop app a significant barrier? * And does requiring an account before starting the free trial make you give up? The current version does require an account to start the trial, and I'm trying to work out whether that's meaningful friction for the people who would actually use this. It's free to try, and I'd particularly appreciate feedback from people who already learn languages through their own videos, anime, films, podcasts or other media. I'm the developer, so I'll be around in the comments to answer questions and discuss how it works. https://subsmith.app

Every time I talk to my older family members, especially my grandparents, I find out a new super interesting fact about them. Last week: my Croatian grandfather served in the French marine corps... Not worth mentioning I guess. I realized that these stories are passed down only by re-telling them. Just think about how much you don't know about your family from 2 generations ago. For this reason, I created ancestree.marindedic.com It's a really cool family tree creation app, where each person gets their own book. Inside it, write what they did, what happened to them, what they were like... whatever you want. Little biographies of your loved ones. Apart from exporting normal and detailed versions of your family tree, you can even export someone's chapters as one long biography. Of course, open-sourced, no account, no server. Nothing you draw or write ever leaves your browser.
