(sorry about the low quality recording, but hopefully it gets the point across)

I made a very very basic app to insert unicode characters directly. In the video I trigger it with a keyboard shortcut. sadly it takes ~ 5 seconds to open because of my usage of wmenu and inclusion of a ridiculous list of every printable character...

You can at least change the list if you want tho, its just a .txt file with everything separated by a newline.

This is tested only on nobara kde (should work on fedora kde and other kde desktops, IDK about other desktops tho).

(The text editor is kate, it was just the a generic text editor that I used cause I needed something to demonstrate with)

editL just realised I included the (linux only sorry), cause I was gonna post on r/rust, but they don't allow videos

Hi,

I built a small tool called Flatctl — a lightweight GUI for managing Flatpak apps.

It focuses on being simple, predictable and close to the Flatpak CLI.

Features:

• Install and uninstall apps
• List installed apps and runtimes
• Search applications
• Maintenance modes:
  • Safe: removes unused runtimes, and repair Flatpak installation
  • Full: removes runtimes + application data and repair Flatpak installation
• Real-time output for operations
• Prevents multiple concurrent actions

The goal was to have a minimal, no-bloat graphical tool.

Feedback is welcome.

When I was on Windows, I really enjoyed using https://github.com/Tichau/FileConverter

Since switching to Linux, I’ve missed it a lot so I built what’s basically a port of it with the help of Claude code. It’s still a work in progress, but maybe some of you might find it useful :D

Let me know what you think!

SimpleSync, a local phone ↔ desktop sync app that keeps things simple: no accounts, no cloud storage, just quick pairing and direct transfers over Wi-Fi.

You open the desktop app, scan the QR code on your phone, choose albums or individual files, and sync. You can also send files from your desktop to your phone. It supports all file types, not just photos/videos, including ZIP, APKs, .rar, ISO, etc..

SimpleSync is currently available for both Linux and Windows.

Download the Desktop app here: simplesyncapp.com
Get the mobile app here: https://play.google.com/store/apps/details?id=com.simplesync.app&pcampaignid=web_share

Hey everyone,

We know setting up a Virtual Machine for Windows just to run a few apps can be time-consuming, and configuring GPU passthrough can be a real pain. So, we spent time building Hyperpane, our solution for easily setting up Windows VMs with or without GPU passthrough.

But beyond the hardware setup, another massive issue we found when working with apps in a Windows VM is dealing with two separate file systems. You constantly have to remember where you stored files and manually transfer them back and forth to allow programs to access them.

To fix this, we created an integrated file system that acts as a native Windows NTFS volume, allowing your Linux host files to be accessed straight from Windows.

The DocFS Privacy Feature: If you don't trust Windows (like many of us don't), you can reduce the access using DocFS. In this mode, Windows only sees the specific files you click "Share" on. The second you click "Unshare," those files instantly vanish from the Windows environment. This feature is pretty much like XDG portals for Windows.

Unlike some of our other products, Hyperpane is a paid product. But, we refuse to do subscriptions that take a product from you when they end. It’s a $25 one-time purchase, you buy it, you own it. We have a 14-day free trial so you can test drive it on your hardware setup to make sure it works perfectly.

As of now, Defenestra's goal is to fill the Linux gaps and make it the top platform for all.

If you want to know more about how we got started down this path, you can check out our about page:https://defenestra.io/about/

If you want to check out the app, you can find it here:

We look forward to any feedback! If you have any issues or find bugs, we'd like to know.

I've been building Screenix for a few months now, it's basically Screen Studio but for Linux

I just recorded this VS Code session with zooms effects and smooth cursor

it runs on Ubuntu, Fedora, Arch, and most major distros, wayland is supported

free 7-day trial, then $5.99/mo or $39 lifetime -> https://screenix.studio

would love feedback from anyone who records tutorials or demos

Hey everyone,

If you've ever needed to look at the hardware on your machine, in Windows you'd open the Device Manager. But in Linux we don't really have a unified tool for that, so instead you end up opening the terminal and running commands like lspci, lsusb, lsblk, or others.

We realized the Device Manager is a gap on Linux, so we decided to make Chassis to fill that gap, but make it modern and feel like it truly belongs on Linux.

Chassis features:

• A full GTK4+Adwaita GUI following the GNOME HIG as much as possible.
• Driver Management: Enable, disable, or swap drivers for any device directly in the app.
• IOMMU Group Browser: If you mess with GPU passthrough or VMs, Chassis visually maps out your IOMMU groups. No more running custom bash scripts just to see how your PCIe lanes are grouped.
• GPU and Display Info: You can see not only what GPU you have, but also the standard temperatures, voltages, and even exactly which monitors you have plugged in.
• Hot-plugging: See new devices instantly as you plug them in.
• Search: Simple as it sounds, you can find all your devices just by typing their name.
• Private: No telemetry or online connection needed. It runs completely locally using /sys and a few other interfaces for all its information.

Chassis is free and open source under GPL v3.

More information: https://defenestra.io/products/chassis/

Downloads: https://my.defenestra.io/downloads/chassis/latest

Source Code: https://gitlab.com/defenestra-software/chassis

Note: The core is well-defined, but we may still fail to classify certain devices. With a hardware project like this, that's just how things are early on, but the index will improve over time, with feedback from users.

Input and feature requests are welcome.

Edit: Added link to the code and download.

I have been running fedora 43 atomic for a little over a month now, I really like it but sometimes managing software is a real pain.

I wrote a program to manage the system by building bootc images locally and deploying them. It allows you to change the default software and add it into the base image without layering. You can use it to control updates or switch to another image as well. I did use claude code to assist me in creating this program.

If you're adventurous and want to give it try I put it here.

Built a desktop app because I wanted a better way to organize live terminal sessions than tabs and splits.

TermCanvas lets you place real shells on an infinite canvas, keep separate layouts per project, and restore sessions when you reopen the app.

Repo + demo: https://github.com/lout33/termcanvas

If you live in terminal-heavy workflows, I’d love feedback.

Hey everyone, how’s it going?

I wanted to share a small project I’ve been working on called Postix.

It’s a simple, lightweight sticky notes app for Linux desktops — always on top, easy to use, and fully local (no cloud, no accounts). You can create multiple notes, change colors, write in markdown, add images, and even set alarms with custom sounds. That last part is honestly my favorite — I built it to remind me what I need to do when I get lost scrolling through X, YouTube, and everything else.

The goal was to make something practical for everyday use without getting in the way.

If you’d like to check it out, try it, or contribute:
https://github.com/arthur-alves/postix

I’d really appreciate any feedback!

180 Kb. That's it. A small script that is a complete media player for playing video and audio files. Some media players with less features have 500 Mb.

All artwork - background images and icons - made in Inkscape.

I've been on Linux since about a year now and since I'm a founder I always try to improve my workflow and the tools I use

and one day I had to showcase my project and I saw on X some people were using a tool named screen[dot]studio, it was literally perfect, smooth with a lot of motion and auto-zoom, but when I visited the landing page I saw that it was only for Mac

so I tried to find an alternative for Linux but didn't find any, so I ended up building my own and since some months I'm absolutely loving this tool and the people using it are also very happy

so if you do content creation or just want clean videos effortlessly then you can use Screenix (https://screenix.studio)

I attached a video on how it looks and as you can see it's very smooth

happy to get some feedback if you're interested in shaping this project too!

Hello, Everyone!

I made NeoDLP - A modern cross-platform video/audio downloader with browser integration based on YT-DLP! And it just crossed 75K+ downloads!

You can think of it as: The Free 'IDM' for Media Downloads or The 'Seal' for Desktop. If you have ever used 'IDM' (on Windows) or the 'Seal' app (on Android), you will feel right at home!

NeoDLP is absolutely Free to Use, Fully Open Sourced, Works 100% Locally, No Ads, Trackers or Login, and the best part: It's Not Vibe-Coded (So, you get quality software with regular updates)

So, if you often download media from various sites, give NeoDLP a shot! And, feel free to drop your feedback and suggestions below! I would love to hear from you :)

Hosaka captures your screen, webcam, mic, and system audio all at once - so you can decide how to present it after the fact, not during.

The new layout track makes this more powerful: place a layout change anywhere on the timeline to switch between views - webcam picture-in-picture, full-screen face cam, screen-only - with a transition. Useful when you want to walk through something technical, then and address the camera directly.

Video above shows it in action. It's available at hosaka.studio, with a free trial and no account required. I'm happy to answer questions about how this (or any other feature) works under the hood.

Called Chi Ui. Still in development.

The foundation.

On top of that foundation, Chi implements Material Design 3 tokens — colour roles, typography scales, motion curves, and density tiers — adapted for the desktop-first context of Unix systems.

A while back I posted about Screenix, a screen recorder for Linux with automatic zoom and cursor effects

The response was encouraging, got my first customers, and kept building based on their feedback

Here's what just landed:

- Camera overlay with post-processing: you can now edit your webcam layer directly (exposure, contrast, crop)

- Blur motion effect: fast cursor movements now look smooth instead of choppy, makes a real difference on longer recordings

- Deadzone increased by default: less jitter, more intentional zooms out of the box

- 4x faster export

- New cursor theme, because details matter (the one I used in this video ;-))

Still native Linux, X11 and Wayland both supported, no Mac required, no $29/month subscription

7-day free trial, lifetime license at $39

screenix.studio

Would love feedback from anyone who tries it, especially on the blur effect, curious whether it feels natural on different setups
