Looking for feedback & collaborators Launchpad Online – a browser-based Launchpad built by an Italian student

Hey everyone! 👋
I’m Vittorio, a 22-year-old Computer Engineering student from Italy.

A few months ago, I decided to combine two of my passions — music tech and web development — and started working on an open-source project called **Launchpad Online**. It’s a Progressive Web App (PWA) that turns your browser into a fully playable Launchpad, either by connecting a real MIDI device or by interacting directly with a digital launchpad grid using your mouse.

The idea came from my love for the Novation Launchpad and my curiosity about how far web technologies like the WebMIDI API and Web Audio API can go. Tools like Ableton Live are amazing but often overwhelming for beginners, so I wanted to create something simpler and more focused, where you can just jump in, press pads, trigger sounds, and enjoy the experience.

Right now, Launchpad Online includes an 8×8 interactive grid (with multiple pages, up to 512 pads total), a custom Web Audio engine for high-quality playback, and real-time MIDI controller support through the WebMIDI API. It’s also a Progressive Web App, so you can install it and use it offline like a native app.

I’m currently developing on the branch `feature/midi-launchpad-webmidi-improvement`, where I integrated the **launchpad-webmidi** library to improve communication with physical Launchpads. It’s working decently, but I’m not completely sure whether this library is the best long-term choice, or if I should instead manage the low-level MIDI communication myself.

Since I’m still quite new to web development, the project is built entirely using plain JavaScript, HTML, and CSS — no frameworks or TypeScript. I’ve tried to keep the structure modular, separating logic for audio, MIDI, and interaction, but I know there’s plenty of room for improvement.

This is a personal side project that I work on in my free time, not something I can dedicate myself to full-time. Still, I’m really motivated to develop it further and eventually complete it.

That’s why I’m here: I’d love to get feedback from more experienced developers, especially about how I’ve structured the project and whether my approach to MIDI (and the use of launchpad-webmidi) makes sense.
And if someone out there enjoys music tech, web audio, or just wants to contribute to a fun and creative open-source project, I’d love to collaborate!

Thanks a lot for reading — and for any advice, feedback, or contribution you might want to share 🙏

How do open-source projects get visibility (and even sponsorships?)

Hello people. I am a frontend developer and I am actively working on an open-source telemetry platform. It's more of a environment related project and the development roadmap is promising. I believe my project has solid value and I hope it gets the attention it deserves.

I often come across new OSS projects that rack up thousands of GitHub stars and wonder how did they reach there. How exactly do other developers do that? Some guidance would be tremendously helpful.

I coded an open-source Monkey Type alternative for programmers (with cool IDE-like behavior)

Hi all!

I’ve been working on Code Typer, a type racer (like monkey type) made specifically for programmers. Instead of lorem ipsum, you type through real code snippets pulled from open-source GitHub projects.

I’ve also added IDE-like behavior such as auto-closing brackets and quotes, plus shortcuts like Cmd/Ctrl + Backspace and Alt + Backspace

Built with Next.js, Tailwind, Zustand, Prisma + PostgreSQL.


Repo: github.com/mattiacerutti/code-typer


Would love any feedback, stars, or bug reports. Thanks!

What is the best way to support a project monetarily? Is there a reason for developers not to have accounts for all popular platforms (patreon, buymeacoffee, liberapay, ko-fi...)

I have recently canceled all streaming subnoscriptions and thought about supporting my favorite developers and creators directly, with part of the money I spend before. I noticed that everyone uses a different provider and asked myself why. It's a bit annoying and I imagine if you let people donate where they already have an account more people would do it.

Arbiter — Open Source LLM Evaluation Library for Python

Howdy y’all!

I’ve been working on an open source evaluation library for Python called Arbiter (https://github.com/evanvolgas/arbiter).

Arbiter is an LLM evaluation framework that provides simple APIs, automatic observability, and provider-agnostic infrastructure for teams that work with AI.

It’s very much alpha software, but I would love thoughts and feedback on the library and roadmap, if anyone has anything they’d be willing to share. I’m especially curious to hear thoughts about the roadmap!

I am building an single binary Learning Management System and looking for contributors.

Hi, I am building a single binary Learning Management System and looking for contributors.

Myself is a Moodle Admin in a University. I found Moodle hard to use and very error prone. Its codebase also has a lot of tech debt causing feature implementation extremely slow. It is using PHP so its plugins are buggy and often not useful because its is hard for develop to build plugins on top of PHP.


Therefore, I start the project Paideia LMS around a Month ago. I have been building this alone, developing, researching, writing doc, making youtube videos...

The education industry landscape is changing, with a shift to AI, the old LMS like Moodle and Canvas fails to keep up. I have hope on this LMS to replace Moodle and Canvas because it is single binary but scalable, built on modern tech like typenoscript, bun, react, payload CMS. But by the effort of myself I can only do so much.

Hopefully anyone might find the project interested and willing to help out. Any contribution or discussion is welcome.

How do open-source projects gather real user references?

I maintain an open-source project that gets a steady flow of daily unique clones, often dozens per day. The point is that it is impossible to track *who* is using it and *how*. Some of those clones are probably bots and hobby users, but I'm sure part of the traffic comes from real companies and production projects.

I'd like to collect project references, not for marketing or vanity, but to understand real-world use cases, improve the roadmap, and show new users that the project is trusted in practice.

For maintainers here:

* **How do you find out who's using your work?**
* Do you rely on direct outreach, community channels, website forms, analytics, or something else entirely?
* Which approaches actually worked for you?

I added a note in the README asking users to reach out, but I'm not convinced anyone will take the initiative unless areg-sdk project is a well-known brand :)

Any insights or examples would be appreciated.

Here is the project: [Areg SDK](https://github.com/aregtech/areg-sdk) (The CTA with the note is in the README)

When You Have Limited Runway, Is Pivoting to Services the Right Call?

so we put weam.ai on autopilot as it was open source and we were going throough funding problems we started choose automatorslab.ai to provide automation service does it loook like smart move or shoiuld we still focus on supporting our previous project, I'm a bit in a grey area right now.

anyone else struggle with the awkward "can I share this idea?" conversation?

I was trying to write a research paper, but I was scared to share the idea or ask for feedback before publishin because I didn't wanna tell my experienced friend "hey please don't steal this" - like, I trust them completely, but you know that anxious feeling of "what if they did....."

It's such a stupid situation because:

You either don't share (and miss out on valuable feedback)
Or you share it but say nothing and just... hope for the best?

Neither option is great, and it's not about trust or being selfish - it's just about wanting to be on the same page about boundaries without making things weird.

Like, you can't just go "please don't take my idea" without sounding like you don't trust them. And NDAs are way too heavy for casual "hey what do you think of this?" conversations.

So I got frustrated and built something: **The Idea Protocol** - Let's pretend I didnt build it cuz I didn't want to seem like 'that person' in the group cuz literally that's how it feels like to set a boundary lol especially when it comes to the random ideas, maybe it's just me

It's basically like open source licenses, but for ideas. You just add one line when sharing:

> "This idea is shared under the Idea Protocol (*IP-FB*). For confidential feedback only."

There are 6 different "licenses" ranging from "strictly private" to "completely open, use however you want." So like if this becomes a thing, both the parties would just know oh okay this is your intention without making it personal - much like foss licenses - I mean I have many repos with it's own licenses but I would never be able to go legal anyway but like there's this standard in our foss world which I am so proud of,


You morally and socially ( ofc legally but yk what I mean ) respect the intent behind the license and at the same time they are not personally attacking you, it's just their preference about their code



Everyone knows the boundaries upfront, so no awkward conversations needed.

Works for everything from research ideas to "should I tell my crush how I feel?" (yes, that's a real use case I included - see the use case page lmao )

It's completely open source and not trying to replace actual NDAs - just fill the gap for casual idea-sharing where legal contracts are overkill

Anyone else deal with this problem or am I just overthinking things? cuz I legit wrote the licenses ( for making it seem like hey look it's a thing, it's nothing personal towards you ) - This is more of me wanting to see if I am the only one who overthinks to this level or maybe some of us think the same lol

OpenSigner – self-hostable key management for Web3/crypto wallets (OSS release, feedback welcome)

Hii!
in my team we just announced the open-source **OpenSigner**, a self-hostable key-management stack for **embedded Web3/crypto wallets**, and we’d love feedback from people who care about running their own infra and avoiding vendor lock-in.

here's some more info: The idea is :

* You run the infra (dockerized services + iframe).
* Keys are created client-side and split into shares (device / hot / shield).
* Signing happens in-memory with a 2-of-3 model, then wiped.
* You plug it into your existing auth (OIDC, passkeys, etc.) so users get a stable wallet without seed phrases or migrating if you ever change providers.

This is meant for teams who want “embedded wallets” UX but don’t want to hand over keys to a black-box SaaS or be locked in forever.

We’d really appreciate feedback on:

* the architecture & threat model,
* the defaults (2-of-3, components, policies),
* anything that looks over-engineered / under-thought from an ops or security POV.

Code & docs:

* Repo: [`https://github.com/openfort-xyz/opensigner`](https://github.com/openfort-xyz/opensigner)
* Docs: [`https://www.opensigner.dev`](https://www.opensigner.dev)

Happy to answer questions and iterate based on your comments.

**Would you trust this?**

Let me know your thoughts :)
