I was tired of context exchange across my claude and codex sessions, so i built a memory & coordination graph my agents can actually use

I'm a Research Engineer at a YC startup, and we ship features pretty fast. I usually run Claude Code, Cursor, Codex, and OpenCode in parallel, developing multiple features, one at a time.

The problem i noticed was that my agents had no coordination, and often confused mutual work, even when working in separate worktrees. As if they had no idea the others existed

So, I built MUON, it's a local app + mcp + cli, a mutual shared brain my agents can plug into. it drives the CLIs you already have and orchestrates them together for multi-feature execution workflows.

I'm still building it. Right now I use MUON to work on MUON, which is a weird but useful dogfood loop.

If anyone wants to poke at it, contributions are welcome. The thing I'm trying to get right is a coordination graph: shared memory and context so agents actually understand what the others (and I) already decided.

I've always been an open-source person, so the code is public and readable. License is Polyform Noncommercial. However, there's an extra grant on top - you can use it for your own work, including your day job, on your own machines. What it doesn't cover is turning it into the company's shared brain for a whole team (Enterprise only)

PeekM2: A real-time dashboard/viewer for your PM2 processes

Note: I'm just a beginner, don't bash too hard on me :/. AI wasn't used to write this post at all and I'd love if you'd take a minute and check the project out!

AI was used to lend me a hand me during the dev of the project, but it wasn't used extensively and most of the UI is just shad/cn, it was used mostly to help me learn Svelte as it's my first time using it :P

Also, for anyone that isn't inside the JS/TS ecosystem or just don't know what PM2 is, it's just a process manager, allows you to control all of your Node/Bun/Deno processes (or even other interpreters) and auto-start them on boot. Find more about it here: https://pm2.keymetrics.io/

Project Repo: https://github.com/AngelCMHxD/PeekM2

Live demo: https://peekm2.angelcmh.com/

I've been looking for PM2 dashboards for quite a while and I've been able to find quite a lot of options, however, none of them were quite what I was looking for.

The official one has a LOT of features, though mostly ones that I don't need, and the only plan with a fixed/public pricing is $39 a MONTH, which is just too much for what I was looking for, and especially for hobby projects.

And for the open-source ones, some of them were too complex to setup, like I don't want to setup a whole PostgreSQL instance just for a PM2 dashboard. And others were over-complicated, I don't really need an user management feature other than just an admin/master password, if I didn't have a dashboard I'd have to give the other maintainers access to the whole daemon anyways. (Though right now you can set up multiple instances, so you can handle access that way too)

So, for mine I built a historical CPU/RAM usage history chart, logs, basic controls to restart/stop/delete processes, and a small uptime chart (that probably needs to be reworked because it only checks every 5 mins, and for it to be reliable it should check WAY more frequently)

Now, I do have other features in mind that I could implement and have them in mind, like these:

  • Discord (or other) webhooks to notify about process changes or downtime.
  • Fix the uptime thing I mentioned before.
  • Add a way to check historical data from other than the last 24h.
  • Related to the one above, limit the amount of historical data stored, as it's currently uncapped and we only use the last 24h, so keep only what's needed
  • Maybe add a way to see the process env variables?

This list is not exhaustive though, and I'm quite open for feedback, even if it's the user management thing I mentioned before that I didn't need, I'll just find a way to make it unobtrusive for anyone that may not want it.

The main point of the project is just keeping it simple for anyone that doesn't want that much, but I could add other features as long as they don't impact the simplicity for anyone that don't want them. Just keeping the "barrier of entry" as low as possible.

I've also deployed a "demo" instance so you can see how it currently looks like, and I've said before, I'm open to feedback!

If you like the idea, please star the repo ;D! It's my first time doing a project and posting it on things like Reddit, I'm just a beginner at these things

Edit: Fixed the formatting... so sad that it didn't worked at first :/

2nd Edit: Also, I'd love to promote Hack Club! It's an amazing non-profit dedicated to incentivize programming for teenagers (13-18 inclusive) and overall just doing cool projects while getting rewards. This project was made/submitted to one of their programs as I'm a teenager myself :D

I built Forms Offline, a local-first forms application that runs entirely in the browser without a backend

I made a completely offline privacy first Forms authoring app.
It's currently a progressive web app. I am planning to convert this into an apk so that I can remove the browser dependency for using the app.

Live: https://deekshithvodela.github.io/FormsOffline/ GitHub: https://github.com/deekshithvodela/formsoffline

The goal was to build something closer to a full forms platform while keeping all data on the user's device. It supports a form builder, conditional sections, rapid data entry, file uploads, photos, digital signatures, dataset management, audit trails, Excel/ZIP exports, and PWA installation.

The interesting part is the offline collaboration model: users can export a form template, share it with others, collect data independently, then export their datasets and merge them using the built-in consolidator with duplicate detection.

It's open source and completely free.

I'd love feedback from developers on the architecture and especially the local-first/offline data model.

What would you improve or build differently?

edit: fixed link text.

Is there any other JS REST API framework that is secure by default, plus OpenAPI support like FastAPI, runtime-agnostic like Hono, Contract-first api like Elysia & TS-rest, and scoped plugins like Fastify?

Differences between Deno, Node.js and Bun

What exactly is the difference between those three runtimes and why do I see Bun mentioned in the same context as Node.js and not Deno?

No runtime wars please. I need to understand the technical and philosophical differences.

Thanks in advance.

EDIT Thank you so much for the very clear explanations. In my view Deno appears to be the only reasonable choice and I will focus on it.
