Built an Unofficial Upstox Mutual Funds API

Hey folks,

I built an unofficial REST API wrapper for Upstox’s mutual fund data using Node.js and Express. Thought I’d share in case anyone finds it useful or wants to contribute.

What it does:

Fetch detailed mutual fund info (NAV, returns, holdings, etc.)
Search funds by keywords/filters
Get historical NAV data
Fast, lightweight server built with Express

Repo: GitHub – Upstox Mutual Funds API (Unofficial)

Note: It scrapes public data from Upstox MF pages. Unofficial, not affiliated with them. Please use responsibly.

Happy to get feedback or suggestions. PRs welcome!

I built a storage engine in rust that guarantees data resilience

https://github.com/crushr3sist/blockframe-rs

Hi everyone! I wanted to share a project I’ve been working on called blockframe-rs.

It is a custom storage engine built entirely in pure Rust, designed around multi-hierarchical chunking with segmentation. My main goal was to solve reliability issues without compromising accessibility, so I’ve implemented RS erasure coding to ensure zero data loss risk, even in the event of partial corruption.

make the data actually usable, I built a service layer that integrates with FUSE (on Linux) and WinFSP (on Windows). This allows the segmented chunks to be mounted and accessed as a standard filesystem, providing full file representation transparently to the user.

I’m currently looking for feedback on the architecture and the erasure coding implementation. If you’re interested in systems programming or storage engines, I’d love to hear your thoughts!

Player of the non-profit student radio

Hi.
For some time now, our radio has had an application written in Flutter, which allows you to listen to our technical university's student radio station.

At the moment the app has:
Player
Displaying what program is currently on

Displaying the above information in the system player (at the very top of notifications).

A subpage with the program schedule (when launched, the application scraps the radio page with the weekly program schedule).

A subpage with statistics on how many minutes/hours you have been listening to the radio since installing the application

Push notification logic for: no connection to the streaming server, interruption of the listener's internet connection, no internet on the listener's device at startup

For those who have not accepted push notifications, a notification (widget) with these alerts appears at the top of the screen when there is a problem.

In progress:
Possibility to report an error, possibility to send information about the currently listened program via e.g. Messenger

More extensive statistics, namely the duration of the longest session, the duration of the shortest session, the day on which you listen to the radio most often

Possibility to like a program in the schedule that interests the listener and notify him that his liked program will start in e.g. 5 minutes

Now the question is, what else would be useful to add to the radio app?

Open source CLI - detect environment variables JS/TS

Have you ever run into issues with enviroment variables in JS/TS projects?

I have, a lot - especially issues that only shows up at runtime or fail silently.

That’s why i build this npm CLI package.

It’s optimized for Sveltekit and Next.js but also works well in moderen JS/TS projects

I’m at a point now where i’m trying to make it more open source friendly - så any feedback on how i can improve that is very welcome.

I built an open-source OAuth Mock Server for E2E testing

Testing "Login with X" in E2E tests is a nightmare because of 2FA, Captchas, and rate limits. I got tired of expensive tools or complex local setups, so I built a free, drop-in replacement.

How it works:

You just swap your provider URL (e.g., Google's auth URL) with in your test environment. It simulates the happy path and redirects back to your app successfully. [`https://oauth.kogiqa.com/`](https://oauth.kogiqa.com/)

Features:

* Works with Google, Microsoft, GitHub, Facebook, etc.
* Custom Data:You can inject mock user info via URL params (e.g., `?name=QA_Bot&email=qa@example.org`).
* 100% Free & Open Source.

Check it out and let me know if I missed any providers you need!

CareDay: A Simple, Open-Source App for Home Daycares

I built a tiny app called CareDay for us ❤️ — we run a licensed home daycare.

We just wanted a simple way to share daily updates with parents: how the kids’ day went, activities, meals, and any important notes. When we looked around, most solutions were full-blown SaaS platforms with monthly fees and far more features than a small home daycare actually needs.

So we built something just for our use case.

CareDay is a lightweight, self-hosted app made specifically for home daycare providers — simple, private, and easy to use. No subnoscriptions. No bloat. You own your data.

Simplicity is the core, especially when it comes to daily tracking and reporting.

We’ve now released it as open source, and we plan to keep improving it over time by adding features that actually support home daycare providers—without sacrificing ease of use.

It was also a fun challenge for us to step into a completely different domain and use our technical skills to solve a real, everyday problem.

If you run (or know someone who runs) a home daycare and care about simplicity, privacy, and data ownership, this might be useful for you.

I’d love any feedback and would be happy to answer any questions you may have 🙌

I built an open-source software, offline Batch Upscaling (Image/Video), BG Removal, and more

Hey everyone! I just released v2.0 of LABOKit, a desktop app I've been working on.
​I was tired of uploading my images to random websites just to remove a background or upscale a photo, so I built this tool to do everything locally on my machine, also... can do batch upload/process!

​Key Features:
- ​100% Offline: Powered by local AI models (rembg, Real-ESRGAN).
- ​Batch Processing: Process multiple images at once.
- ​Upscaling Performance: Supports both Vulkan (GPU) and PyTorch (CPU) for non-GPU users.
- ​New Plugins: Includes a QR Code Generator, Quick Vectorizer (Image to SVG), and Dithering FX.
- ​Steins;Gate Theme: Because I love the anime, I added a Divergence Meter UI style.

​It's fully open-source. I'd love to hear your feedback or suggestions!

Looking for contributors to help build an open-source visual archiving tool (Firefox Extension + Dashboard)

Hey everyone 👋

I’m currently working on MorgiFile, an open-source, non-commercial project designed to help users (especially designers) archive, categorize, and manage images from the web.

MorgiFile consists of a Firefox extension that allows you to save images via right-click, a local Python backend, and a web-based dashboard where saved images can be managed by categories. The project is currently in Beta and fully functional, but still open for improvement.


I’m a designer building this project mostly on my own, with basic coding knowledge and a lot of AI assistance. Because of this, parts of the code could definitely be improved and cleaned up.


I’m looking for volunteer contributors who would like to help with:

\-Code optimization and refactoring

\-Improving project structure and maintainability

\-General feature polish and cleanup


This is a fully volunteer-based, non-commercial project, and there is no financial compensation involved.

Whether you’re a beginner looking to contribute to open source or an experienced developer who enjoys improving existing code, all contributions are very welcome.

There are already issues labeled "Help wanted:" to help you get started.

MosaicGrid – Easy Mosaic Grid Layouts for SwiftUI Apps

I’ve been building an open-source SwiftUI library called MosaicGrid. It helps you make custom mosaic-style grid layouts in SwiftUI without fighting the default grid views.

It supports both horizontal and vertical layouts, with control over how big each tile is, how tiles line up, and how much space sits between them. There are small helpers, like spacer tiles, so you can shape the grid and leave empty cells where you need them.

https://github.com/hainayanda/MosaicGrid

Feedback, ideas, and contributions on the repo are welcome.
