Open source Java library for the LegiScan legislative API

I’ve been working on a small civic tech project that might be of interest: a Java adapter for the LegiScan API. It’s now on Maven Central and open sourced under MIT.

The library covers the full API, supports bulk caching of datasets, provides a simple CLI tool, and includes POJOs for type-safe JSON handling. You can use it either as a dependency or as a standalone fat jar.

GitHub repo: https://github.com/poliscore-us/legiscan

This is part of the larger PoliScore effort to make legislation more understandable and accessible (about). We also recently moved all PoliScore code into a dedicated GitHub org: https://github.com/poliscore-us/poliscore.

Would love feedback, or to hear if anyone else is working in the civic tech / legislative data space.

Debating about switching from AGPL 3.0 to Apache 2.0

I'm debating if I should make a certain package in my ecosystem Apache 2.0 - as opposed to it's current license being AGPL 3.0 - could use some input!

Background: The ecosystem I've built is replyke.com \- which is an open-source framework for building social products and implementing social features in existing products. It is built of the following building blocks:

1. Client side libraries - I've built 9 packages for implementing Replyke in ReactJS and React Native apps. Context providers, hooks, complete comment section UI and more - these are all available in a single monorepo under Apache 2.0
2. Express.js package - this is the one I am wondering about - it is all the server side logic. The implementation of all routes, models and controllers.
3. Hosted platform - dashboard for managing users, content, reports, analytics etc - this part is closed and will probably stay so (though I keep finding myself going more and more open source)

I am thinking about making the Express.js Replyke package also Apache 2.0 - but not sure what the right call is.

Is it currently affecting adoption that the express package is AGPL 3.0? Haven't had anyone say so, but I'm wondering.

The idea is that I provide the hosted version and AGPL 3.0 prevents others from also providing a hosted version, but for personal use anyone can use that.
Am I looking at it wrong? I am pretty fresh to the open source world as a contributor, and even Replyke didn't begin as open source, so I'd appreciate any input!

New OS for my android

Greetings. I have a question to ask. I would like to change my mobile's OS (my current one is android) as my phone is pretty old but I want to squeeze a bit more life out of it but I feel all of the bloatware and my phone no longer receiving updates is slowing it down. I have a Xiaomi Redmi note 9. Do any of you know any mobile OSs that support a ride hailing app (preferably Bolt or Uber) and WhatsApp?

What if Linux Had Its Own Power BI Desktop? Open-Source Project Idea

Hey ,

So, after countless hours of frustration trying to get Power BI Desktop to run smoothly on Linux, I finally had that lightbulb moment:

Why not just build a proper alternative for Linux users?

That’s how this idea started — building an open-source, Linux-friendly alternative to Power BI Desktop.

Instead of fighting with workarounds, we could have a tool designed from the ground up for our ecosystem. And I’d love to build this together with the community.

Do you think Linux needs its own BI tool?

What features would you like to see if this project takes off?

Would anyone here be interested in contributing (coding, design, testing, ideas) ?


If this resonates with you, let’s start shaping this project as a community effort

Cross-platform RSS readers?

Looking for a good, cross-platform (specifically Android, Windows and Linux) RSS reader. Preferably FOSS, but paid open-source is fine too. Android app is a must (or at least a really really good PWA), but web-based reading is totally cool for Windows and Linux as long as everything syncs. May be open to self-hosting, but not trying to sink a bunch of time into getting things up and running.

I totally thought that something like this would exist, but searching for one has made it feel like I've been looking for a unicorn so far. Does anyone have any recommendations?

Ev_Ap - Event Attendance App Open Source

Hi, I just recently graduated as a Computer Science and I wanted to share this open source that I've been working on since I was in college.

[Ev\_Ap](https://github.com/TriangleBear/Ev_Ap)

I made this for my organization to lessen or completely not using papers in events. The main purpose of this is to automate the attendance by using a NFC card (a custom card that is given to members that joined the organization), instead of the members having to write their names in a piece of paper for attendance or register for an upcoming event, they will just tap the NFC card and get to the event.

The features are still in progress or partially working:
\- Registration of New Members
\- Creating Events (for automated attendance)
\- Marking Attendance
\- Exporting Data (Registration, Attendees, Members, Points of Member)

Please do check my repo and help me maintain, crash bugs, add features.
In advance, Thank you for the help.

RFC: If At First You Don't Succeed....

Requesting feedback and comments on my weekend opensource project. It's the first time I've ever created oss so be brutal. Also looking for pointers on great discord groups to post in to raise awareness.


https://github.com/marketplace/actions/ai-release-bot


I originally built an AI blog analyzer tool and launched with limited interest. Rebuilt it this weekend based on feedback into an opensource top level funnel tool for software projects. The goal is to gather all release details for projects and create a ready-to-post blog to help drive top level awareness for the project.


So far I've completed an MVP. It's tailored towards Rest based projects with an OpenAPI spec sheet as that's my primary workload as an engineer. The goal is to make it robust and dynamic to handle all types of projects. Also pull in better context about projects and changes.

An open-source alternative of Marker.io

Hey Guys, I'm building my first open-source tool.

It's a visual feedback tool that captures bug reports and UI feedback with maximum context and minimal user effort. Unlike traditional forms, it enables point-and-click feedback with auto-screenshots, logs, and integration into Slack. (Customer-first, not an Internal tool)

I am new to this. I need contributors and lots of advice, like:
How to track usage?
How to update?
How to maintain?

Also, I need feedback.

If you are a builder, please try!

I gain Experience, you get an app

Hi,

I’ve recently started developing small, practical software tools that I can personally use while also learning in the process.

Right now, I’m exploring ideas for software that isn’t readily available (or polished) on Linux but could be genuinely useful across platforms. If you have any recommendations for tools you’d like to see, I’d love to give them a try.

As a starting point, I’m planning to build a cross-platform clipboard manager. I know there are already many out there, but my goal is to replicate the simplicity and usability of the Windows clipboard manager as closely as possible.

Tech Stack🍔:

-Backend: Neutralino.js (lightweight, cross-platform)

-Frontend: React.js


Goals 🥅:

>Memory usage: < 20 MB

>Supported platforms: Windows, Linux, macOS


Thanks, and I’m open to suggestions for other useful software ideas too!


For fast readers 🏎️: I’m building lightweight cross-platform apps for learning — share your ideas, and I’ll turn them into useful tools!

Should I opensource my SaaS (MinuteMVP) or add affiliate marketing so I can focus on building other products?

Hey guys,

I built MinuteMVP - an AI tool that generates validated SaaS ideas with complete MVP blueprints in 5 minutes. It's solving real problems (85% of founders waste months in analysis paralysis), getting decent traction, but I'm facing a dilemma.

The situation:

Currently profitable but not life-changing money yet
I keep getting pulled into feature requests and optimizations
I have 10+ other SaaS ideas I want to build using my own tool
Spending more time tweaking MinuteMVP than building new products

Option 1: Open Source It

Release the code, build community
Focus my time on building other SaaS products
Potential for community contributions and growth
Risk: competitors could clone it easily

Option 2: Implement Affiliate Marketing

Add revenue streams through tool partnerships (Replit, development platforms)
Create passive income while I build other products
Keep it proprietary and controlled
Risk: might complicate the product

My real question: As founders, do you think there's more value in doubling down on one product or using a "portfolio" approach where you build multiple smaller SaaS products?

I'm torn because MinuteMVP could be bigger, but I also see massive opportunities in the niches it's revealing to me.

What would you do? Open source and move on, monetize differently, or just keep grinding on the one product?

Any insights from founders who've faced similar decisions?

SciBitHub, a collaborative citizens science platform

Hi everyone, I'm exited to share with you a project I created in the last months, its called "SciBitHub", its a website dedicated for creating and contributing to research projects that are open for everyone (collaborative research), a project has multiple tasks where each task could be data collection, data labelling or just a survey. The app also provides a space for scientific discussions and debates in different domains. The goal of this project is to facilitate access to science and research domain for everyone with no background needed (these kind of apps are very rare, one similar website is www.zooniverse.org).

The website was made using these technologies:

frontend: Next.js + Tailwind + ShadCN
backend: Supabase (Auth, Database, Storage)
deployment: Vercel (free tier)
file storage: Supabase Storage + MinIO (local)

Due to limits in experience and mainly in resources (100% free), the website has some limitations:

The file and dataset uploads are disabled in production (since datasets are expected to have a big size, only profile photos and cover images are stored in Supabase storage).
The project architecture and some technical choices may not be optimal since this is my first time working with these technologies.

For these reasons, I decided to make the project open-source and made the code public on GitHub, so if anyone of you would like to help improve SciBitHub, here's what I'd love help with:

file storage alternatives
UI/UX refinements
unit testing & performance optimization
internationalization (multi-language)

Any pieces of advice from experts are welcome whether it be about the code itself or about handling the open-source aspect (also first time for me).

You can find the GitHub repo here : https://github.com/MAY55A/SciBitHub

Live site : https://sci-bit-hub.vercel.app/ (some features are disabled due to mentioned limits like uploading files)

Let’s build something meaningful together for the science and dev community 🌱

Created this open sourced npm package just to deal with the responsiveness. Contributors are always welcome

Building responsive apps and showcasing them across devices can be a headache. Switching between different screen sizes, browser tools, and third-party emulators often slows down the workflow.

That’s why I built react-uiframe 🎉 – an open-source React component that makes it effortless to preview your app inside beautiful, realistic device frames (mobiles, tablets, desktops, and more). With a plug-and-play setup, you can drop in your app’s URL or component and instantly see how it looks across multiple devices – all inside your React project.

Why react-uiframe?

Easy device emulation inside your React app
Perfect for responsive testing & client demos
Lightweight, customizable, and developer-friendly
Great for portfolios, landing pages, and live previews

This project is fully open source and I’d love for you to try it, use it in your projects, and help make it even better. Contributions are more than welcome – whether it’s new device frames, performance improvements, bug fixes, or documentation enhancements.
