I built a comprehensive RSS Developer Suite with 12 tools - Feed parsing, validation, caching, accessibility, WebSub, and more!

I've been working on an RSS Developer Suite - a comprehensive toolkit for RSS developers and publishers. It's completely open-source and built with Next.js + Node.js.

Made privacy visible — now open-sourcing the free version of my project, CleanTrail

Hey everyone
I’ve been building CleanTrail, a browser privacy tool designed to make privacy visible instead of silent.

Most blockers work quietly in the background — I wanted something that actually shows users what’s being tracked, blocked, or cleaned up in real time.

I’ve now open-sourced the free-tier logic (MIT License) for transparency. It includes:
• Privacy Profiles (Strict, Balanced, Relaxed)
• Adaptive mode (auto-adjusts based on site type)
• Real-time tracker & ad blocking
• Privacy score meter (A–D rating)
• Auto cookie cleanup (optional cookies)
• Fingerprinting detection
• Basic analytics (top trackers, cleanup logs)

I kept backend and Pro-tier features private for security, but the free-tier logic is fully available to browse and learn from.

Would love any feedback from fellow builders or anyone who’s worked on privacy or browser extensions before — especially around open-sourcing sensitive projects responsibly (it’s my first open-source project!).

Also happy to hear if you notice any issues or possible improvements in the code itself — I’m trying to make the project both transparent and educational.

I am building this

Hey guys, I am currently building a PHP platform named Papyrus to create portfolios, blogs and project documentations. The idea is to build this from scratch and allow developers to have maximum control over the project. The architecture encourages individual modules in order to help organize all resources inside module. Please have a look at it and give me your feedbacks. You are welcome to contribute to the project if you are interested.
Thank you.

Is .devcontainer.json suitable PR material?

I find it most useful for niche or legacy projects that use old stacks that make it a pain to get started. Especially with PHP where you need many system dependencies.

Will open source projects appreciate tooling contributions like .devcontainer.json?

Testing open source applications got annoying so now I'm trying to do something about it

tldr; I got annoyed spinning up a bunch of different open source applications, so I created an open source app that wants to make this process much quicker/easier. Please let me know if this is just my problem or if you can relate...

I've been spending the last couple of weeks experimenting with a ton of different self-hosted and local AI open source tools, and it started getting annoying.

It was probably taking an average (with huge variance) of 10 minutes to get each app working right, which doesn't seem like much at first. However, when you are experimenting with dozens of different apps, the time starts to add up. I think Docker Hub does a pretty good job at making this easier, but I thought it would be better if there was one place where you could just download any GitHub repo with one click (and delete it with one click). Docker Hub takes care of this problem for Docker containers, but there are more ways to spin up open source projects than just Docker containers.

Am I the only that gets annoyed by this, or can anybody else relate?

I was also thinking something like this could make open source apps more accessible to the average person, but I may be getting ahead of myself there.

Stos - A Kotlin Multiplatform App for Browsing Issues

Stos is an open source Kotlin Multiplatform app that lets you browse, filter, and discuss issue lists.

The main goal of the project is to learn KMP with Jetpack Compose through real development experience and to create a client across different platforms.

Github repository - https://github.com/m4ykey/Stos

This project is based on the StackExchange API and aims to provide a clean, mobile-friendly way to browse and explore questions, answers, and user data from the StackExchange network.

If you're interested in contributing - whether by implementing API integration, improving UI in Compose, or experimenting with Kotlin Multiplatform - you're more than welcome to join!

The goal is simple: learn together and build something useful!

Why is everything a SaaS nowadays?

More and more I see projects calling themselves FOSS alternatives to popular tools, and the first thing on their landing page is a pricing section.

Sure, they might let you self-host it with Docker or something, but… why do I need to host a video editor and open it in the browser? Just let me install it like a normal program.

I'm not trying to bash on FOSS projects — I obviously get the need for income, and I even support a few projects myself.

It’s just that so many of these come from web devs using Next.js, React, etc, and it feels like every project now has a cloud dashboard and subnoscription tier attached.

Maybe that's just where software development is heading as a whole, given how many Electron-based products we see nowadays.

This is just a rant, but I’m curious how others feel about this trend.

Which open-source tool do you wish had a better demo?

I started making short open source tool tutorials and keep noticing how many great tools don’t have demos that actually show what they do. Some are super useful but still feel hidden because no one has shown them off properly. Are there any that you wish had good demos or tutorials?

Contribute to Open Source

Hey everyone,
I’m an engineering student currently learning Go and Kotlin, I have been exploring some orgs for potential Google Summer of Code 2025 participation.

I want to ask that how people contribute to open source. I am a beginner and I want to contribute to open source and participate in GSoC. The challenge I’m facing is that most open-source projects look massive — even the “good first issues” feel complex when I try to set up the project or understand the codebase.

Here’s what I’d like advice on:

1. How do beginners realistically start contributing to such large open-source projects?
2. How do you pick issues that are actually beginner-friendly (not mislabeled)?
3. Should I begin with smaller standalone projects before targeting GSoC orgs?
4. Any recommended repos in Go, Kotlin that are truly beginner-accessible?

I wrote zigit, a tiny C program to download GitHub repos at lightning speed using aria2c

Hey everyone!

I recently made a small C tool called zigit — it’s basically a super lightweight alternative to git clone when you only care about downloading the latest source code and not the entire commit history.

zigit just grabs the ZIP directly from GitHub’s codeload endpoint using aria2c, which supports parallel and segmented downloads.
