I've been building OpenTubeX, a YouTube client for Windows, macOS, Linux and Android, with experimental iOS builds. You can watch without ads or a Google account, and your subscriptions, playlists and history stay on your device unless you turn on sync.

Most of the code is written by Claude Code and Codex. My part is deciding what goes in, testing it, and sending it back when it's wrong. Every change also has to pass an end-to-end test suite before it gets merged.

Some of the things it does:

• Subscribe to channels without an account and group them into profiles
• Choose per channel whether videos, Shorts, live streams or posts show up in your feed
• SponsorBlock and DeArrow
• Per-channel playback speed and quality, custom shortcuts, skip silence
• Tabs, a queue, and a mini-player that keeps playing while you browse
• Themes and a configurable Home page
• Optional sync between devices, end-to-end encrypted on a compatible server
• Plays from other sites yt-dlp supports too

It's still in beta. You can get it as a Flatpak, Snap, the AUR, WinGet, Homebrew and more, or on Android through our own F-Droid repo or Obtainium.

Happy to answer questions, including how building it with agents has gone.

I've been spending some late nights building an app, Mizan (ميزان) which means "scale" in Arabic, to help me and my son with drum and piano practice. The app brings transcription, sheet music, instrument visualizations, and practice exercises together. It analyzes music using open-weight models (HT-Demucs and MuScriptor).

You can start with a YouTube link, import a MIDI or MusicXML file, or work through the built-in lessons without transcribing anything.

Here’s what it does:

• Transcription and audio separation. Turn a recording into draft instrument parts and isolated audio stems.
• Local or cloud processing. Run transcription on your machine, or use a GPU worker in your own Azure, Google Cloud, or AWS account.
• Interactive notation. Follow synchronized sheet music, guitar and bass tablature, and chord charts during playback.
• Instrument views. Animated piano, guitar, bass, and drums, with hand and fingering guides. Piano has both perspective and overhead views.
• Practice controls. Slow down playback, loop sections, jump between bars, and use a metronome and count-in. Toggle note names, fingering, and drum sticking.
• A mixer for practicing parts. Solo or mute individual tracks, adjust their volume, and switch between the original recording, separated stems, and synthesized notes.
• Built-in lessons for drums, piano, guitar, and bass. These include progressive exercises, genre-based studies, and original artist-inspired exercises. There are drum rudiments, coordination exercises, grooves and fills, plus scales, piano chord progressions, and instrument-specific technique studies. Lessons include practice guidance and starting and target tempos, with backing accompaniment where provided.
• Music discovery. Search YouTube and public MIDI sources from the app, or browse popular music.
• Library organization. Keep songs and scores in folders, revisit saved analyses, and rerun transcription with a different model.
• MIDI and MusicXML import and export. Bring in existing scores or take your results into another music tool.

The transcription isn’t perfect. It can miss notes or get parts wrong, so I think of it as a starting point for figuring out a song rather than a finished arrangement. You can also skip transcription entirely and use it to practice existing scores or the included lessons.

It’s open source and Windows-only for now. There are demo videos in the README if you want to see it in action.

I've been really into the AI phone agent products that have popped up in the last few months (e.g., AgentPhone, Poke etc) but what I don't love: the audio, the transcripts, who you talked to and what was said, all sitting with a third party company. For calls with real people in my life, that felt like a lot to hand over.

So I built my own version that runs entirely on my Mac. You call a normal phone number, a local model answers, and nothing about the conversation leaves my machine. During a call the only thing it talks to is the phone line itself.

What's running locally (MLX on Apple Silicon):

• Speech to text: Parakeet TDT 0.6B
• LLM: Qwen3.5 4B by default (9B if you have 32 GB), 4-bit
• Text to speech: Kokoro 82M

How it reaches the phone network: it registers over SIP with Telnyx or Twilio straight from your Mac. A setup wizard takes your carrier API key so can buy a number or connect one you already have. It's pretty cheap, around $1 a month per phone number. (I'm moslty using Telnyx)

What it does today:

• Answers and places real calls
• Interruption: talk over it and it stops mid-sentence
• Replies in roughly 1 to 1.5 seconds on real calls on my M5 Pro
• You can choose between multiple models
• Other agents (Claude Code, Codex, etc.) can make calls through a small CLI: call, listen, say, hangup
• If you'd rather trade privacy for a smarter brain, it can also use your own endpoint or the Claude or ChatGPT subscription you already pay for. Local is the default. So no additional monthly payments for AI Phone tools if you have a sub.

Limits, up front:

• macOS on Apple Silicon only
• You need a Telnyx or Twilio account with credit (a US number is about $1/month, standard call rates do of course apply, but Telnyx gives you $10 dollars for free when you sign up, which is enough to play around with)
• English only, one call at a time
• It's early. It works for me, but I'd love to hear where it breaks for you. please feel free to report as many gh issues as you want. I'm also working into best practises for contribution for anyone who wants to contribute to the project!

VirtoMir: Open-source, web-based VM management panel for KVM QEMU libvirt (self promo)

Hello,

I’d like to introduce my hobby project, VirtoMir.

Links for those who would like to take a look:

Live Demo: https://onurbaydas.github.io/VirtoMir/demo/ (contains dummy data)

GitHub: https://github.com/onurbaydas/VirtoMir

My blog post: https://onurbaydas.com/posts/virtomir/

VirtoMir is an open-source control panel for managing KVM/libvirt virtual machines on Linux servers via a web interface. My goal was to create a tool that is as user-friendly as Cockpit, but with a deeper focus on virtualization-specific features.

I won’t try to hype up VirtoMir—especially when giants like Proxmox and Incus exist; that’s not my intention. Essentially, you install a single program and can then access the control panel at `localIP:8420`. Most core features are already implemented and supported. So far, the project has received 2 contributions and 4 stars on GitHub.

I’ve been developing the project using AI agents, which has allowed me to write a large amount of code in a short time, bringing it to an advanced stage on paper. However, due to resource limitations, I haven’t been able to test it on bare-metal systems. Currently, I’m testing it by configuring Linux VMs—running on my own machine—as nodes, but I don’t consider these tests sufficiently reliable. I definitely plan to conduct tests on bare-metal hardware; for instance, by installing Linux on older PCs with varying hardware specifications, setting up a cluster, and verifying the core functionality. Any help, support, or even just feedback—positive or negative—from those interested in this field would be incredibly valuable.

Advanced features like clustering, Ceph, HA (High Availability), and DRS (Distributed Resource Scheduler) have been tested and appear to work within a VM environment. However, given that these are complex features and the code was developed with the help of AI, their reliability is currently unproven. To ensure this doesn’t just become another "AI-slop" project, it is essential to test these features on bare-metal hardware, monitor their performance, and document any bugs or shortcomings.

Moving forward, I plan to pause the addition of new features to focus on solidifying the project's stability on a single-host setup. Key features include console access (SPICE, VNC, etc.), support for backup systems (Veeam, Commvault, Veritas, etc.), email-based alarm notifications, and the ability to modify resources for running virtual machines without shutting them down.

I am sharing this here to gather feedback from those who develop open-source projects, wish to contribute, are simply curious, or have any constructive criticism—positive or negative.

Thank you for reading.

I built a desktop app to manage my SSH config without the usual GUI-editor problems: reformatted files, lost comments, or a broken config after a bad save.

Every save:

• changes only the lines you edited. Comments, order, indentation and line endings stay.
• is checked with ssh -G first. If OpenSSH rejects it, nothing is written.
• backs up the old file and replaces it in one atomic step. History shows a diff of each backup and can restore it.

Also: lists your SSH keys and which hosts use each one, makes new Ed25519 keys, turns hosts off without deleting them, handles Include files, and groups hosts.

No account, cloud or telemetry. Rust + Tauri 2, plain JS UI with no build step. Builds for macOS, deb/rpm/AppImage (x86_64 + ARM64).

AI use: Built using Claude Code as a pair programmer. I designed it to solve real pain point for manaing ssh hosts and reviewed every change. The parser is tested against real configs.

It’s early (v0.1.1). I’d like feedback, especially if you have an unusual config that breaks it.

https://github.com/AnkitKumarDhal/ariaWatch/releases/tag/v0.3.0

Hello everyone!
I've been working on this TUI download manager based on aria2, because well i tried finding the lightest and fastest download manager, but i couldn't find anything better than aria2 in the terminal. I tried a few TUI options for it but i couldn't find any modern TUI (anything that didn't look it was from the mid 2010s) so i tried to make one myself.

It started out as a simple monitor for an already running aria2 server, but with this v0.3 release, it turns into a full-fledged download manager, with support for:

• adding download URLs directly, even magnet links are supported
• adding .torrent files
• keeping history of downloads
• download actions (pause, resume, remove, delete)
• information about the download
• able to monitor a pre-existing aria2 server

I'd love for people to try it out and give feedback on what issues they face, and what things can be improved. Do give it a try! The binary release is for Linux x86_64 only for now,,, with other OS's support planned for future releases.

About the other TUI's looking from mid-2010s claim,,, mine doesn't look any better either, but its still in the very early stages, and v0.5 is going to be a major UI overhaul with a UI that i have planned beforehand hehe :3

Thank you!

• Trust is a concern. Why should I trust and use Password Pusher?

• What are the potential security risks of running my own version internally?

I wanted to join TeamSpeak servers from any device without installing anything, so I started building a browser client at the end of July. Three months and ~330 commits later it’s usable enough that people I don’t know are using it, and some are even self-hosting it.

How it works: the browser can’t talk TeamSpeak’s UDP protocol, so a small gateway runs one Rust connector per user and bridges WebSocket ↔ TS3. Voice, chat, whisper, file transfers and permissions work. You can also use themes and an account sync with no email (Mullvad-style number + optional password).

Almost all the code was written by Claude Code. My part was deciding what to build, testing it against real servers and phones, and saying “no, that’s wrong” a lot. The hardest bits were the handshake and a voice server that sends commands out of order.

MIT licensed, self-hostable with one Docker container.

Happy to answer questions, including how the AI part actually went.

I needed to keep the same business rules running on different targets. AI wasn't solving it consistently, and the solutions I found were too complex to integrate into the lightweight pipeline I was already using. So I ended up building my own some months ago.

Today, JSOL ( currently v0.2.97 ) keeps my AIs in check while compiling 70+ examples and even itself to JavaScript, TypeScript, PHP and Python.

JSOL uses a deliberately simple syntax, a set of standard functions designed to remove ambiguities between languages, and contracts to ensure the compiled code produces the same results on every target.

Should you bother learning it? Probably not. But you don't have to learn it: you can point your AI to the language spec and let it do the work. What you get in return is a pipeline that verifies the result is still bit-for-bit identical across every target.

If you need to maintain business rules across several targets, give it a try.

That’s it. That’s all I gotta say for now :-)

Hello everyone, I'm a CS undergrad researching on making better Indic keyboards.

I've been programming in various languages for a long time now. Still, for this project, I had to think through a lot and had to use LLMs as mentors, because the topic was sitting right in the middle of Linguistics, HCI and Theoretical Computer Science.

Edit: I accidentally clicked post, here are the links:

I also made a preprint, but the boolean framework is slightly outdated now: https://doi.org/10.5281/zenodo.20467634

hey everyone! i believe our reddit communities probably have quite a bit of overlap, so i just wanted to share some of the new rules/tooling that we're implementing at r/TrueOpenSource to deal with "slop", reduce duplication in the OSS community, and take another step toward a world of OSS dominance and sustainability. i wish you all luck here and hope you find this helpful!

I had just released Naughty Keyboard, it's a tool for testing input fields, the design is simple.

The app comes with values packs, each value pack is a set of problematic data, with one shortcut we can write the problematic data, with other we can switch the pack, the app is cross-platform, full GUI + CLI (there is nkb emit, so we can export the values and use in own tests form the code). Like the project? Please give it a star. GitHub If you got any questions, features requests feel free to share them :-)

Right now there are 208 values, and packs like export breakers, extreme numbers, some specific data, in the future there are plans for 1000+ values, you can read here: full list of packages. Like I said it's simple, keep it in background, use when needed, in the feature I will expand the ability for creating own packages and shortcuts, let's say we would automate whole input fields on website with one shortcut :D And I think the tool can automate some boring work too, because right now I'm using the copy/write mode for testing values, but if in easily way other pepole could create own packs for work, so there is potential.

I won't lie that all works perfect, I tested it on systems I got, but there are some known bugs that I'm fixing right now :-)

Please, don't ask me about some girls emojis or anything like that, the "naughty" in the name is in sense of "testing" not some girl things :( You now like a big list of naughty strings.

Full features list:

• One shortcut, one value - Alt+Shift+N (Option+Command+N on macOS, Ctrl+Alt+N on Linux) clears the line and types the next value of the current pack into whatever window has the keyboard. Previous and restart are one chord away, and every chord can be changed.
• Values that explain themselves - each one carries breaks (what it usually breaks, and why) and expect (what a correct application does). The pack file, nkb show and the report block all say so.
• Invisible characters made visible - the palette draws one as a marker, ␣, instead of showing nothing, and counts every value four ways: graphemes, code points, bytes and UTF-16 units.
• Know where you are - the palette shows the value that comes next and a counter of how far through the pack you are, and the value window searches the values of every pack at once.
• A bug report in one chord - Alt+Shift+B copies a block for the last value: which value, from which version of the pack, typed as what, how large, and whether all of it arrived. The value is written in a form someone else can type back, never as the marker the palette drew.
• Never takes the keyboard - the palette is a display driven by shortcuts and does not take focus, so the cursor never leaves the field you are testing.
• Clipboard mode - put values on the clipboard to paste yourself, for one window or for all of them.
• Packs you can check - a pack is a plain TOML file, nkb lint checks it against the format rules, nkb fmt puts it in canonical shape, and nkb new-pack writes the skeleton.
• Made for scripts too - nkb emit prints a pack as JSON, CSV or one value per line, escaped or raw, optionally as base64. Every command has exit codes you can branch on.
• Offline, free, no telemetry - GPL-3.0, no account, and it opens no network connection.

The technologi is Rust + slint. And Yes I'm using AI, I'm open about it (we can see Claude at PR, contributirs + there is note about ai-assited workflow).

So r/fossdroid decided to follow the same exact rules with the opensource sub.

And they actually copy pasted the same rules for their sub so ppl including me, said their piece about it. U can see my comment in the screenshot. And a few minutes ago I just got a message that Im banned 😂😂

I asked what is the reason for banning me and which rules I broke and I'm waiting for a reply

Btw, Im neither pro or against AI. If it works for what I wanna do I will use it, if it doesnt I wont.

But this Hitlerism in 2026 is amazing. The great minds of the past that fought for us to enjoy free speech would be really sad and disappointed with our evolution as a species 😎

Hi everyone! I maintain TransparentTorProxy (TTP), an open-source Linux CLI tool that routes system TCP and DNS traffic through Tor using nftables, with other traffic blocked unless explicitly bypassed.

I'm looking for a few people willing to test installation and basic operation on:

• Debian / Ubuntu - .deb package
• Fedora - .rpm package
• Arch Linux - build using the repository's PKGBUILD

The project has automated tests, but I'd like feedback from different desktop setups, especially around installation, DNS handling and restoring connectivity after stopping TTP.

A short test would help:

1. Install TTP using the instructions in the README.
2. Run sudo ttp start, then ttp status and ttp check.
3. Try your usual applications and note any unexpected behaviour.
4. Run sudo ttp stop and check that normal connectivity returns.

Please use a disposable VM or a machine where temporary connectivity problems are acceptable. TTP requires root and changes firewall rules and DNS handling; it is not intended for high-risk anonymity needs or as a replacement for Tor Browser or Tails/Whonix/Qubes.

What to report:

• Distribution and version
• TTP version and installation method
• Whether installation, start, check and stop worked
• Anything confusing, broken or missing

A one-line "everything worked on distro X" is useful too. No coding experience needed, and no need to explain what you use Tor for. Please review any diagnostic output before sharing it and remove personal information.

You can reply here or use GitHub Discussions. Bugs can go in Issues; security vulnerabilities should follow SECURITY.md.

Thanks for helping me understand how TTP behaves outside my own test environments!

Hey everyone,

I've been working on something for a while and I think it's time to show it. It's called transport-io, an open source library for real-time stuff over WebTransport. If you've used Socket.IO you'll feel at home, it's heavily inspired by it <3

But first the problem, because most people I talk to have never heard of WebTransport!

WebSockets run on TCP. TCP gives you everything in order, which sounds nice until a packet gets lost. Then everything behind it sits and waits until that one packet is resent. Your chat message, your cursor position, the AI response that was streaming. All of it waits. On good wifi you'll never notice. On a train or on a phone jumping between towers, your users will.

Want messages that are allowed to get lost? Welcome to the hell of WebRTC. It can do it, but it was made for browser-to-browser calls, so talking to your own server means a signaling server (which is usually a WebSocket lol), STUN/TURN, SDP offers and answers, ICE candidates, and a WebRTC stack running on your backend. All that to send some mouse coordinates.

Enters WebTransport. It runs on HTTP/3 (QUIC), and Safari shipped it in March, so every major browser has it now. You get a bunch of streams on one connection, and a lost packet only blocks the stream it was on!

You also get datagrams, messages that can just get dropped. They're not raw UDP, they're still encrypted and everything, they just never get resent. Perfect for cursors, where an old position is useless anyway.

The catch is the raw API gives you bytes. You end up writing your own framing, your own routing, matching responses to requests... nobody wants to write that.

That's what transport-io does for you.

You write one contract, shared by client and server, and every event says whether it's allowed to get lost:

import {
  defineContract, reliable, unreliable, rpc, streaming, type MapOf,
} from 'transport-io'
import { z } from 'zod'

export const contract = defineContract({
  chat:   reliable(z.object({ room: z.string(), body: z.string() })),
  cursor: unreliable(z.object({ x: z.number(), y: z.number() })),
  save:   rpc(z.object({ text: z.string() }), z.object({ revision: z.number() })),
  ask:    streaming(z.object({ prompt: z.string() }), z.string()),
})

export interface AppMap extends MapOf<typeof contract> {}

Then on the client:

client.emit('chat', { room: 'lobby', body: 'hi' })  // will arrive
client.emit('cursor', { x: 12, y: 40 })             // might not, and that's fine

const { revision } = await client.call('save', { text: 'draft' })

for await (const token of client.stream('ask', { prompt: 'explain QUIC' })) {
  render(token)
}

client.emit('cursor', { x: '12', y: 40 })  // doesn't compile

Zod validates everything that comes in, and TypeScript yells at you about everything that goes out :)

Where it fits:

• cursors, game state, presence, anything where newer beats complete. That's unreliable, and it goes over datagrams
• chat and anything that has to arrive, reliable
• streaming AI tokens. Every stream is its own QUIC stream, so stopping one doesn't touch the others. And when you stop it, the generator on the server actually gets cancelled, it doesn't keep burning tokens for nobody
• plain request/response with call(). Also its own stream, so a slow one can't block a fast one

Want to see it without setting anything up? Run this and open two tabs:

bash npm i transport-io @fails-components/webtransport-transport-http3-quiche npx transport-io dev --demo

It's early and it has its quirks (Safari is the big one for now, it falls back to a WebSocket). Everything I know about is in KNOWN-ISSUES. So any kind of help is welcome, issues, PRs, or just telling me what broke :)

About 10 days ago I released an open source alternative to paper (https://github.com/tidydesigns/tidy)

Since then we got 50 users and 34 stars. It’s a humble start but I’m super excited about this project.

We’re trying to reduce the friction between design and engineering.

Since the 2 roles are becoming more tightly coupled we think there’s lots of unique ideas we could implement here !
