Open Source Chatting App?

Is there any open source chatting app that allows full customization? For isntance it needs to fulfill some requirements, so here they go:

\- It needs to support at the very least android

\- It needs to have some sort of encryption to avoid leaking the contents of the messages

\- It needs to have the server and client open source, since I want to add new features on top of it

\- Having some kind of resource that helps modifying the code would be good but not mandatory.

I built a Rust CLI for secure, temporary file sharing on AWS S3. With S3 on server encryption, links/files expire automatically, and it costs almost nothing to run (AWS Free Tier)

Introducing Univer MCP – AI-Native Spreadsheets for Everyone

Hey r/opensource! 👋

I wanted to share Univer MCP, a tool that lets you drive Univer Spreadsheets using natural language. Basically, it brings AI directly into spreadsheets, so you can automate, analyze, and manipulate data more intuitively.

Who can use it?
Any app that uses Univer Spreadsheets can integrate with Univer MCP and leverage AI to enhance spreadsheet functionality.

Would love to hear your thoughts—how do you see AI transforming spreadsheet workflows in open-source projects?

Embedded device, Qt6 vs Qt5

Hi everyone,

I am working on an embedded product using Yocto that launches a Qt Application at startup.

I am trying to make sure we comply with open source licenses correctly, but I am a bit confused about the implications. Here is the situation:

* The application uses **Qt6**.
* It also uses **Qt Virtual Keyboard**, which I understand is **GPLv3 only**.
* The rest of the Qt6 components we use are under **LGPLv3**.

From what I understand:

1. Since Qt Virtual Keyboard is GPLv3, **the whole application must be GPLv3**, which means we would need to make the source code of the app publicly available.
2. Because Qt6 is LGPLv3, we must allow the end user to **replace the Qt libraries** with modified versions. But do we need to provide documentation or noscripts for rebuilding the Yocto image, or is it sufficient to just not prevent the replacement technically (firmware signing, hardware locks...) ?
3. If we used Qt5 instead, the LGPLv2.1 modules would **not require the ability to replace Qt**, so simply publishing the application source code would be sufficient, is that correct?

I’d really appreciate clarification from anyone with experience in embedded Qt products.

I want to make sure we comply without overcomplicating things for users.

Thanks in advance!

Finally my extension just got published on both chrome and firefox

Recently I worked on building extension for both chrome and firefox, inspired from my earlier project, react-scribble-pad, that was published as a complete npm package.

Scribble pad is a simple yet a sleek and powerful tool that lets you draw, sketch, make notes or use It as a whiteboard on top of any website.


Try it out:

I built an open-source P2P tool to solve my own privacy frustrations. Could I get your feedback?

Hey r/opensource,

I'm a long-time C++ dev and I just finished my first solo full-stack project, born out of my own frustration.

I was tired of the privacy risks of sending files and text snippets between my phone and PC. So, using my spare time, I taught myself full-stack development and built a solution called PrivyDrop.

It's a free, open-source tool that uses a direct P2P (WebRTC) connection to share files and text. It's fully end-to-end encrypted, and your data never touches a central server. Think of it as a secure, private clipboard.

I'm deliberately not including links here to avoid the spam filter. The project is still in a very early stage, and what I need most right now is honest feedback from fellow developers.

Does this sound like something you would use?
What are the first things that come to mind that I should improve or add?

I'd be happy to share the GitHub and live app links in the comments if anyone is interested in trying it out or reviewing the code. The repo is on GitHub under david-bai00/PrivyDrop if you want to search for it.

Thanks for your time!

I built a fully open-sourced OpenCL 2.0 abstraction platform (RetryIX UCAL) to revive dormant GPU compute capabilities (AMD/Intel/NVIDIA)

Hello open-source friends 👋,

I’d like to share a project I’ve been working on for months — RetryIX UCAL, a completely open-sourced Universal Compute Abstraction Layer based on OpenCL 2.0, with full compatibility across AMD, Intel, and NVIDIA platforms.

🔧 What it is:
- A C-based abstraction layer for OpenCL 2.0
- SVM memory, device query, and fallback-safe memory allocation support
- Compatible with consumer-grade GPUs (e.g., RX 5700, Vega, Intel iGPU)
- Fully open-sourced under permissive license (MIT / BSD / your license name here)

🌐 GitHub Repo:
https://github.com/ixu2486/retryix_opencl ← Open-source only repo

🔍 This project is part of a larger initiative, but only the pure open source portion is shared here, in compliance with subreddit rules.

I hope this helps revive OpenCL usage or inspires hybrid memory projects beyond CUDA/ROCm 🧠💡

Happy to discuss or receive feedback! 🙌

EzAntiAntiCheat

EzAntiAntiCheat

Hi everyone,

I’m working on EzAntiAntiCheat, an open-source project designed for research and experimentation with kernel-level anti-cheat systems. Its purpose is to provide a safe framework for studying and managing situations where aggressive anti-cheat software interferes with each other, such as conflicts between Riot Vanguard and other anti-cheat platforms.

The project is fully open-source on GitHub: https://github.com/PalorderSoftWorksOfficial/EzAntiAntiCheat

I’m looking for contributors interested in:
• Kernel driver development
• System-level security research
• Safe experimentation with software conflicts and aggressive protection mechanisms
• Documentation, testing, and tooling improvements

Notes:
• This project is intended purely for research and educational purposes.
• It is not designed to bypass or disable anti-cheat systems for gameplay.
• Improper use may render software unusable; please use responsibly.

Contributions, feedback, and collaboration are very welcome!
If this post violates community rules please contact me instead of instantly banning me from the subreddit so i can fix the post from the issue!
Extra Note: EzAntiAntiCheat completely wipes the anti cheat driver and if its gone the game might reinstall or crash as an fail safe

Looking for contributors to start a new open-source project in C# (.NET 8, portfolio & beginner level)

Hi all,

I’d like to start an open-source project in C#/.NET and am looking for a few contributors who want to learn, code, and build something useful together. The goal is to keep it beginner-to-intermediate friendly while still trying to create a clean and readable codebase(clear repo, issues, PRs, documentation).


What I’m looking for in contributors:

• Some experience coding in C#/.NET (no need to be advanced—willingness to learn is most important).

• Comfortable using GitHub for issues, pull requests, and project management.

• A few hours a week to commit.

At the moment I have a few ideas like creating a secure chatting app like discord or something similar, a finance stock simulator game, or make a website similar to Reddit where you can post in forum groups.


If you’re interested, comment or DM me with your background and any project preferences.

Messaging app.

Hello I am using WhatsApp for a long days. And I switched to signal a years ago. And I found one thing crazy in this messaging apps. In WhatsApp I can send files upto 2 gb with E2E. But in signal can't send it. Only supports 100mb. And compress the file or image always. So I tried to find many other secure apps. No app is there. If anyone find secure messaging app with no limit of file transfer size. Message here or can we built it

Can you make parts of monorepo public and other private?

🙏 Apologies if this is somewhat silly question, but I don't have a lot of experience in OSS area.

I assume that this will depend on the “platform” where the code is hosted, mine would be GitHub. The natural instinct tells me that this is not possible, but maybe there are some workarounds?

I have a GH org, so I can break down the stuff I want to open source into individual repos, but I have a use case for monorepo, so it's kind of hard to decide, and I realize that this might be a trade off that I need to make.

I've developed a social network post validator with TensorFlow(ML)

As many of you already know, many social networks have the big problem of always having a lot of noise and a lot of posts that contribute nothing of value to the communities. I've developed a solution for this and I want to share it with you. This is the same solution that https://goconnect.dev/ implements to determine whether a post is valuable to the community or not.

Here the GitHub link: https://github.com/HeyBaldur/ai-post-validator

It basically validates whether the post has high, low, or no value. It also works with any post on any social network, but basically only with topics related to software development.

Trouble uploading pdfs to Tabula

Yesterday I used a great tool for extracting tables from pdfs. https://tabula.technology/

It worked well for my first 3 files, but now the files I'm trying to upload just hang on "waiting to be processed..."

Any ideas how to address this? The first time I tried these files, I accidentally disconnected from my hot spot before anything uploaded. I'd like to try clearing the cache, but can't seem to find it.

I also tried renaming the files


Any help is very much appreciated!
