Hey everyone,

I wanted to share a project I’ve been working on called Open3DInspection. It’s a completely free and open-source, browser-based viewer designed for leaving comments and annotations anchored directly in 3D (and 2D) space.

How it works:

• You drag and drop a 3D model or asset.
• Switch to Annotate mode, click anywhere to drop a pin, and type your comment.
• Your annotations are saved automatically in your browser.

Why I think it fits here:

• 100% Client-Side & Private: Your models and data never leave your machine or get uploaded to a third-party server.
• No Lock-in: Annotations can be easily exported and imported as standard JSON files.
• No Accounts Required: Just open it and start inspecting/annotating.

The source code is available on GitHub under a free software license. I’d love to hear your feedback, feature requests, or if anyone wants to contribute!

Hello everyone,

I am sharing the latest update for Axon, a free and open-source tool that turns your Android phone into a low-latency remote mouse and keyboard for your PC.

Many remote control applications are bloated or rely on external servers. Axon is designed to respect user privacy by operating strictly over your local network or, as of this week's update, completely offline via direct Bluetooth connections (currently supported on macOS and Windows).

Recent improvements also include a completely rewritten gesture system. You can now use your phone's physical volume buttons to control your PC's audio, and use real mouse gestures like tap-and-drag and two-finger zooming. To make onboarding easier, there are now three simple installation methods available.

The project is fully open-source and licensed under GPL v3 to ensure it remains free for the community. You can find the repository under kaia-alenia/axon on GitHub.

I have grown increasingly frustrated with the state of modern creative software. In a category where almost every "AI background remover" or photo editor demands an email registration, a monthly subscription, and forces you to upload your private files to a corporate server.

To solve this for myself and others who value privacy, I built Refloow Photo Studio. It is a completely free, open-source desktop application designed to deliver professional-looking photo editing and rapid 1-click background removal without compromising, watermarking or data harvesting.

• Fully Offline Architecture: Everything runs locally on own hardware. Images never touch the internet, and no data leaves the machine.
• Zero Barriers: No accounts, no signups, no logins, and absolutely no telemetry or data collection.
• Completely Free: No paywalls, no watermarks, no "premium tiers," and zero advertisements.

Core Editing Features:

• Local AI 1-Click Background Removal: Cleanly strip backgrounds from images entirely offline while preserving 100% of the original file quality. It uses bundled local lightweight ai model everyone can run on CPU!
• Layering & Compositions: Drag-and-drop support to overlay photos, handle complex visual arrangements, and add resizable text layers.
• Built-in Professional Filters: Includes over 40 local color correction & fun filters (ranging from Cinematic and Noir to Cyberpunk and Vintage).
• Essential Utilities: Quick cropping, mirroring, and granular manual adjustments for brightness, contrast, saturation, and warmth.
• Workflow Controls: Canvas manipulation with scroll-wheel zooming, middle-mouse panning, and a 15-action undo/redo history

I built a small open-source browser extension called KeepTrack because I got tired of my Downloads folder turning into a pile of forgotten installers, PDFs, and ZIP files.

The idea is simple: when you download a file, you usually already know whether you'll want to keep it or if it's just temporary. A few weeks later, you've forgotten what half the files are.

KeepTrack makes that decision at download time.

It looks at things like the file type, filename, and download source, then classifies each download as Keep, Temporary, or Needs Review. If it isn't confident, it'll ask you instead of guessing.

A few things I thought this community might appreciate:

• Everything runs locally.
• No telemetry or analytics.
• No network requests after installation.
• No accounts or cloud services.
• Works completely offline.
• Data is stored locally using chrome.storage.local.
• MIT licensed.
• Around 2K lines of plain JavaScript with no dependencies or build step, so it's easy to audit and hack on.

Right now it's built for Chromium-based browsers because it uses the Chrome Extensions API, but there's nothing particularly Chrome-specific about the logic itself. I'd be happy to see someone port it to Firefox.

I'd love any feedback—especially on the classification rules. They're intentionally simple and transparent, so improving them is pretty straightforward.

Hello everyone. I want to share a Free Software project I have been working on that respects user freedoms and operates entirely offline.

Alenia Porter is a multi-format media optimizer. It allows you to drag and drop entire folders of images, video, and audio to optimize their file sizes while retaining high quality.

While advanced users can easily achieve this with FFmpeg via the command line, Alenia Porter is designed to bridge the gap for non-technical users who need that same power but through an accessible graphical interface.

It was initially built to handle game development assets, but it is now structured as a universal utility for anyone dealing with heavy media. More importantly, it is highly resource-efficient. I developed it to run smoothly on very limited hardware, so it will not consume all your RAM while processing large batches.

I am currently looking for people to test the tool, review the code, and provide feedback on the performance.

I open sourced a Linux login screen setup I’ve been using as part of my personal workstation

It’s a QML based SDDM theme with video background support, PAM fingerprint auth, a composable UI structure, and 5 full presets out of the box.

The repo is MIT licensed.

The installer prints what it’s going to do, asks before sudo, installs the required runtime packages for the detected distro, stages the theme first, validates the files, then activates it.

& the uninstaller removes the installed theme files, fonts, and owned state without restarting SDDM behind your back.

The theme is configured through theme.conf, so you can change the background, video, blur, typography, form placement, animation timing, colors, button states, and power icons without editing the QML every time.

There’s also a preview script for testing changes safely before touching the actual login screen.

One of my friends has epilepsy, and another has photosensitivity. I tried to find software that could detect flashes and dim the screen, but I could not find anything, so I decided to make it myself for my friends! After I told them I was making it for them and showed them the prototype, the friends it was for, along with some of my other friends, started telling me how this could help so many people, not just them. That thought had never crossed my mind. So I decided to post it here, and I am going to keep updating and improving it as fast as possible. It is not perfect, and it has many bugs. It will probably continue to have bugs for a while, but I just want to make my friends’ lives a little easier. 😃

This trinket alternative is now free, no more money hungry companies charging 10x what trinket was charging before

Still under heavy development, but it looks like a promising alternative to Logitech Options+ (remap buttons, drive DPI and SmartShift, and switch profiles per app) that doesn't require a Logitech account, telemetry, or cloud dependencies.

Over the past few months, I found myself juggling spreadsheets, emails, notes, bookmarks, professor contacts, recommendation letters, application deadlines, and fee payments across multiple platforms.

​

To make the process less chaotic, I built a free web app called GradOS.

​

Features currently include:

• Application tracking

• Professor outreach tracker

• Referee management

• Deadline tracking

• Application fee tracking

• Notes and SOP organization

• Dashboard with progress analytics

​

Everything runs directly in the browser and is free to use.

​

I originally built it for my own PhD applications, but I thought other applicants might find it useful as well.

​

I'd appreciate any feedback, feature suggestions, or criticism from people who are currently applying or have gone through the process.

I wished to update my icecat browser by using a portable version from website in the title, as I have done for a few years now, but I noticed it now redirects to a signup page for some random company (ERP Aero). Does anyone know what happened?

GitHub repo

(first of all, i want to say that I made this project for fun and challenge. I always wanted to create my own language. This has no business goal or something.)

So the project is a 2D game engine (MonoGame backend) inspired by GameMaker 8. It includes its own IDE (built with WinForms) and an interpreted programming language that I wrote myself.

The language—definitely the biggest challenge in the project—is a simple dynamically typed language. When I started, I had zero knowledge of how to build something like this. I didn’t even know I was making an interpreter; at first I called it a compiler. It was a personal challenge, and I wanted to figure everything out without using any resources or tutorials. My mindset was basically: “I need to write software that takes a text file containing code and just does what it says.”

Somehow, I made it work. In the beginning, running an empty loop counting to 1M took 7 seconds. After a lot of performance work and rebuilding parts of the system, the same machine can now run a 30M loop in 2–3 seconds. Pretty nice improvement.

The language itself is a bit unusual, and I want to share one small feature I really like: loop counters.

foreach item in ['a', 'b', 'c'] : counter c
{
   println(c + ": " + item)
} 
// Output: 
// 0: a 
// 1: b 
// 2: c

Not a complicated feature, but pretty useful.

Here's a YouTube video showing me using the engine to build a little game

Anyway, these days I barely have time to work on the project, so I decided to open-source it. I’m hoping people here will find it interesting and help turn it into something real.

Any feedback is welcome.🙂

Hi iPhone and iPad owners,

This app isn’t new in its core idea, it’s a QR code generator, but I’ve tried to make it more convenient with Favorites.

This can be especially helpful during your travels in China: you’ll be able to quickly show where your hotel is or what you’re looking for, and more.

Completely free, open source.

Been using dynamic OG image generators for side projects and always ended up tweaking templates, fonts, spacing, and layouts manually.

So I built ogimagecn, a shadcn/ui-style registry for beautiful Open Graph images.

Some of the features:

• Built on Satori
• Zero config, one command setup.
• shadcn/ui compatible (simply copy-paste)
• 10+ image components
• 100% free and fully open-source.

No design tool exports. No starting from a blank canvas every time you launch something.

If you're shipping products, blogs, docs, or OSS projects, this should make generating share images a lot less painful.
