Open Source Chrome Extension for Visual Web Scraping – Self-Host or Use Cloud

Hi everyone!

I just released OnPage.dev, an open-source Chrome extension for visual web scraping.

Key features:

Select elements visually with hover highlights
Smart scraping with auto-scroll
Export data to CSV or JSON
Run locally with Node.js backend or use the hosted cloud version at onpage.dev

The extension is fully open-source, so you can self-host and keep your data private.

GitHub: https://github.com/OnPage-Scraper/OnPage-Scraper

I’d love feedback, suggestions, and contributions. Open to feature ideas, improvements, and bug reports!

Legal note: Please scrape responsibly and respect site terms of service.

QRPorter — local Wi-Fi file transfer via QR (PC ↔ Mobile)

I built QRPorter, a small open-source utility that moves files between desktop and mobile over your LAN/Wi-Fi using QR codes. No cloud, no mobile app, no accounts — just scan & transfer.

# Features

- PC → Mobile file transfer: select a file on your desktop, generate a QR code, scan with your phone and download the file in the phone browser.
- Mobile → PC file transfer: scan the QR on the PC, open the link on your phone, upload a file from the phone and it’s saved on the PC.
- No extra mobile apps / accounts — works via the phone’s browser and the desktop app.
- Local-first — traffic stays on your Wi-Fi/LAN (no cloud).
- Cross-platform — desktop UI + web interface works with modern mobile browsers (Windows / macOS / Linux / iOS / Android).

# Requirements & tested platforms

- Python 3.12+ and pip.
- Tested on Windows 11 and Linux; macOS should work.
- Key Python deps: Flask, PySide6, qrcode, Werkzeug, Pillow.

# Installation

You can install from PyPI:

~~~bash
pip install qrporter
~~~

After install, run:

~~~bash
qrporter
~~~

# Troubleshooting

- Make sure both devices are on the same Wi-Fi/LAN (guest/isolated networks often block local traffic).
- Maximum 1 GB file size limit and commonly used file types allowed.
- One file at a time. For multiple files, zip them and transfer the zip.

# License

- MIT License

How should open source contributors be rewarded—equity, payments, or something else?

We’ve been thinking a lot about how to go beyond the usual “thanks!” and actually reward contributors in a more meaningful way. We are building an enterprise offering on the project and I want to share the upside with our community. Opensource is one of the greatest parts of software, but I feel like there are a lot of great contributors that keep everything afloat without $$.

One big motivator for contributing to open source is *using* the software for your own business/project—that’s a natural alignment. But then there are the weekend warriors who just like a project, and I feel like if **we’re building on top of their work, they should get a slice of the pie too.**

Some ideas I’m considering:

* **Equity pool:** Treat contributors a bit like advisors—award equity in the parent company for quality contributions. More long-term buy-in, but how do you set the floor? Does *every* contributor get some?
* **Cash bounties:** Have a pool of money and a list of high-priority issues with $$ attached. Motivating, but feels more transactional and short-term. I've seen this with mixed results.
* **Hybrid / tiered model:** Almost like Kickstarter rewards. Contribute a bit → recognition/merch. Contribute a lot → cash. Contribute consistently → equity.

The worry is making everything too transactional—e.g., people stop reporting bugs because “they’ll just post it with a bounty next week.” Equity feels like stronger buy-in, but it’s complicated. Equity only pays out if everything goes great, otherwise its worth 0.

Has anyone here seen a good model for this? How do you balance building a strong community with fairly rewarding people whose code you actually use?

I built Supacrawler, an lightweight Go service for web scraping, crawling, screenshots, and monitoring

Hey r/opensource,

I’ve been working on Supacrawler, a fully open-source and lightweight project in Go for web scraping, crawling, screenshots, and monitoring.

It’s built with concurrency in mind (goroutines + Redis/Asynq for job scheduling) and ships with Playwright support for handling JS-heavy sites. It exposes a small set of REST endpoints like:

`/scrape` – extract structured content (Markdown, JSON, HTML, link maps)
/crawl – distributed crawling with depth/link controls
`/screenshots` – full-page rendering with Playwright
/watch – detect and notify on site changes (this is on app only for now)

I recently put together local benchmarks comparing SupaCrawler with Selenium, Beautifulsoup, and Playwright on python. Everything is open source (Apache 2.0) and contributions or feature requests are welcome!

Here's the GitHub link: https://github.com/antoineross/supacrawler

Thanks for checking it out! Always curious to hear how people would use a tool like this or what features would be most useful

Squiggle - open-source Grammarly

I used to pay for Grammarly Pro but didn't renew a couple months ago. While writing a blog post today, I thought: why not just build my own AI-assisted grammar tool where I can plug in my own API key for spelling and phrasing suggestions?

So I built one this afternoon. It works pretty well already, though there’s plenty of room to improve.

Feel free to try it out, fork it, or send a PR (will review when I can):

OpenSplit - Cross Platform Split timer with a big focus on customization via CSS. Free, open source, looking for development help (and testers soon!)

Hi friends, I've got a lot of friends who run on Linux and Mac and are somewhat frustrated by the options that are out there, and even on Windows I was really looking for something a little more modern looking/feeling than LiveSplit to shake things up, so I decided to make one: https://github.com/ZellyDev-Games/OpenSplit

To be clear, this is not a usable product yet, it's pretty close to an alpha. This post is geared for developers who might be interested in helping, and people interested in testing in a few weeks.

Where I'm hoping to bring interest is

CSS styling with drop in skins (it's a Wails app, so the backend is Go, and the frontend is a React app, so web developers in particular will feel at home)
Cross platform, with working global hotkeys (Windows done, need someone good with mac/X APIs. I think Wayland is dead in the water, but knowledgeable folks would be great to talk to!)
Free, open source, permissive license. Do what you want with it.

Where the project is at

Very early development. To reiterate this post is geared towards developers who want to contribute or runners who might be interested in testing in a few weeks.
Basic UX/UI skeleton, you can open it, create split files, operate the timer, etc
Basic data models and file/IO to persist them
Pretty decent unit tests

What the project needs

Anyone interested who knows or wants to learn Go and React (with typenoscript)
MacOS developers. The hotkey system provided by Wails wasn't sufficient, so I made a platform specific system for Windows witht he Win32 API. This needs to be replicated on macOS and Linux
Linux developers. Largely for the same reason, specifically if you can think of a global hotkey solution for Wayland
Testers, but not quite yet. In a few weeks it could be ready to hand off for some VERY early alpha/dev preview testing.
Auto splitting. I don't even know where to start with this yet :D

How to get involved

Best place is the ZellyDev Games discord: discord gg slash xcrHKCsGmv select the "OpenSplit" option from the onboarding screen
Check out the README, CONTRIBUTING, and getting_started at the project's github: https://github.com/ZellyDev-Games/OpenSplit

Thanks folks, I'm very interested in hearing if you have thoughts, requests, or advice for the project.

Tip for an Open-Source Image Upscaling App

Hi,
I run a website that offers a free vector conversion tool. Since vector conversion works best with high-resolution images, I am looking for a free, open-source image upscaler.

I found this tool, which uses WebGPU and WASM in the browser: [https://github.com/lxfater/inpaint-web](https://github.com/lxfater/inpaint-web). Do you think it’s a good choice? The results are not bad, but maybe you know of a better open-source app.

My main concern is server resource usage (CPU and RAM). Ideally, the image upscaler should not put too much load on the server.

**My server specs:**

* 2× CPUs – 8 threads Xeon 1.70 GHz
* 8 GB RAM
* 40 GB storage

Currently, CPU usage is around 20%, and about 6 GB of RAM is still free.

Alternative Android OS for Niche Phone

I'm looking for a way to completely degoogle my android-phone. Problem, my phone is quite a niche one (Moondrop Miad01) so it basically appears on no compatibility list whatsoever. Any idea which android os would work for it?
Or in general, is there a chance that LineageOS could run even though my phone isn't listed as supported device?

Where to host open source utility: does it matter?

I'm working on a small open-source text utility that's privacy-focused (runs entirely locally without any servers). I still want to provide a hosted static site for people to use the utility without having to download and run it themselves. For the open source community, does the hosting platform matter - specifically GitHub Pages (with custom domain) versus Netlify? Do contributors and users have a preference?

My main consideration is whether GitHub Pages offers better transparency and verifiability—making it clearer that the deployed site matches the repository code. The primary advantage of Netlify would be access to basic, anonymous traffic metrics (like daily page view counts). But not sure if it matters?

Tau Net & Agoras


For years, the promise of decentralization has been a core goal of the tech world. Yet, this promise has often been overshadowed by a reality where power remains concentrated in the hands of a few developers, governance becomes a social popularity contest, and software is vulnerable to human error. Today, we turn a new page by introducing a project designed to solve these fundamental challenges.

**What is Tau Net? A Truly Decentralized Network**

At its core, **Tau Net is The User-Controlled Blockchain.** Unlike traditional projects, Tau Net is not manually coded by a team of developers. Instead, it is automatically generated—or **synthesized**—from the collective will and logical specifications of its participants using program synthesis. This means that the people who use the network directly determine its behavior, its rules, and its future. Users are no longer passive participants but active architects of the system.

**A Paradigm Shift in Governance: Governance by Specification**

Tau Net's most groundbreaking innovation is its "Governance by Specification" model. This puts an end to endless debates, ambiguous proposals, and manual voting. On Tau Net, participants express their intentions and the rules for how the network should behave in a formal language. The system then logically analyzes these specifications, automatically identifying all points of agreement and disagreement within the community. The network synthesizes its own updates based on the agreed-upon logic, with mathematical proof of its accuracy.

**Powering the New Knowledge Economy: Agoras ($AGRS)**

A revolutionary network deserves a revolutionary economy. **Agoras ($AGRS)** is the native token of the Tau Net ecosystem, and it is far more than a simple currency. Agoras is designed to fuel a next-generation marketplace where high-value assets are traded, such as:
* Formalized and verified knowledge and algorithms.
* Smart contracts that can reason, and autonomous artificial intelligence (AI) agents.
* Decentralized Artificial Intelligence (DeFAI) assets and computational resources.

**Our Mission: Large-Scale Collaboration Between Humans and Machines**

Ultimately, the mission of Tau Net is to pioneer a new era of large-scale, automated collaboration and development between humans and machines. Our goal is to build a future where consensus is reached automatically, software is created flawlessly, and collective intelligence can be harnessed to solve problems on a global scale.

This is more than an introduction; it's an invitation to join us on a journey to redefine the future of the internet and collaboration.
