🌍 We built OpenStock — a free, open-source stock market tracker powered by AI

Hey everyone again, because somehow my post was removed by moderator with a reason stating that this is not Open Source, so here we go again, I hope this time they don't remove it, and just in case they remove this I want to say those who are really interested in open source and amazing innovation created within the community can join our official sub reddit at r/OpenDevSociety, if you want to explore things, because we do need people to build up a community, Hope you will take part and help this amazing open-source community grow

I’m Ravi, founder of Open Dev Society — a open-source community for the world.

Over the last few weeks, my friend Priyanshu and I have been working on something called OpenStock — an AI-powered, open-source platform where you can:

• Track real-time stock prices
• Get AI-generated company insights
• Set personalized alerts (coming soon)
• Explore market data without any paywalls

We wanted to make something that students, beginners, and professionals can all use freely — and even contribute to.

Build dashboards like Lego: grid + form + state, should I open-source it?

# 🧩 TL;DR

Thinking of open-sourcing a React-based WYSIWYG dashboard editor — grid-powered, state-driven, and backend-agnostic. Would you use or contribute?

# ⚙️ What it is

A lightweight, React-Grid-Layout editor that lets users drag, resize, and configure(edit panel properties, imagine editing a chart, or an email editor) dashboard panels visually.

* Grid engine: React Grid Layout for layout control
* Panel editor: Formik wrapper for easy panel configuration and customisation control
* State orchestration: Redux (draft/publish, undo/redo)
* Backend-agnostic: consumer defines their panel persistence layer
* Extensible SDK: add your own panels, data sources, or visualizations

# 💡 Why open source it

There’s a gap between BI tools (Grafana, Superset) and generic UI builders.
This sits in the middle — a domain-neutral dashboard editor toolkit you can embed anywhere.

Would a toolkit like this be useful to you?
What features or docs would you want to see from day one?

what is stopping you from contributing to large open source projects?

Hi everyone. For those of you that are interested in getting into open source, and contributing to some larger projects, what is the biggest blocker for you? What do you find most difficult/annoying about contributing to open source projects? What needs to change to make it easier for you to contribute?

from other threads across reddit in the past, i have seen that the biggest reasons are usually related to codebase complexity, lack of time, and tedious PR review processes, but I would like to poll for opinions to see if that is still the case.

I made an open-source tool, CyberPatchMaker, to create tiny update patches for large apps (e.g., turn a 5GB update into 50MB).

I built an open-source (AGPLv3) binary patch creator in Go called CyberPatchMaker, [I couldn't think of a better name tbh\], with both GUI and CLI tools. It's for developers who distribute large applications (like games) and want to send tiny updates instead of making users re-download everything.

You can check it out on GitHub here: https://github.com/cyberofficial/CyberPatchMaker

I've always been frustrated by the experience of getting a massive multi-gigabyte update for what feels like a tiny bug fix out to users. I checked out many other applications, they felt dated, and some cost like putting a down payment on car for some unknown reason. So made my own with the features I found useful.

CyberPatchMaker uses binary diffing to find the exact changes between two versions of an application and packages them into a small, efficient patch file.

My main goal was to make it safe and reliable. It's packed with safety features:

Triple Verification: Uses SHA-256 checksums to verify files before, during, and after patching.
Automatic Backups: Creates a selective backup of only the files being changed before touching anything.
Automatic Rollback: If anything goes wrong during the patch, it automatically restores the backup.

I also added a few key features to make it flexible for both developers and end-users:

GUI & CLI Available: It comes with powerful command-line tools for automation (patch-gen, patch-apply) and an experimental GUI for those who prefer a visual approach.
Self-Contained Executables: You can generate a single .exe file for your users that contains the patch and the applier.
.cyberignore File: Just like .gitignore, you can tell the tool to ignore sensitive files (.env, keys), user data (saves/), or temp files.

The project is written in Go and is fully open-source. I'd love for the community to take a look, offer feedback, or even contribute. If you think it's a cool idea, a star on GitHub would be amazing. If you got ideas for it, feedback is more than welcomed.

The project is fully documented and packed with info in the 'docs' folder but feel free to reach out if stuck or have questions.

Thanks for checking it out if you do take a gander at it.

Made an open-source LC-3 formatter to make assembly less painful.

Hey folks 👋

I’ve been playing around with some LC-3 assembly projects recently, and got tired of the usual pain points:

- inconsistent indentation

- random .FILL spacing

- unreadable trap vector code

- the “why is my label misaligned again?” kind of stuff


So I decided to build a tiny Rust-based toolchain for LC-3, mainly for fun (and sanity).

Crate: https://github.com/robcholz/lc3-toolchain

Github: https://github.com/robcholz/lc3-toolchain


It currently includes:

- Linter – catches common syntax and semantic issues (e.g. duplicate labels, invalid constants)

- Formatter – auto-formats code to a clean, consistent style

- Command-line tool with subcommands (lc3 fmt, lc3 lint)

- 100% written in Rust 🦀 (fast and clean)

I know LC-3 isn’t exactly “production tech” — but I think small, educational architectures deserve good tooling too. I’d love feedback from anyone who’s into compilers, Rust CLI design, or just nostalgic about college-level ISA projects.

If you ever wrote ADD R1, R2, #1 and wondered why your assembler hates you, this tool might save your evening.

Would really appreciate:

- feedback on command-line UX

- ideas for new checks or formatting rules

- PRs / issues if you find bugs!

I’m trying to make this a friendly little niche project — something that makes learning low-level programming a bit less painful.

Thanks for reading!!!

Browser in Browser, remote browser

I am thinking of a thing called browser in browser. It's GUI is served through HTTP, like in a headless environment (Linux) you can use a modern browser on it, given better display quality and usability compare to `browsh`, `lynx`. On the other hand, this is essentially a HTTP server, which can be deployed anywhere. When I'm in high school we can use chrome book, but only chrome is allowed to use and with a strict blocking. If you can serve this in a Google Cloud, AWS VM and you can use this to bypass this restrictions.

I have made a prototype, and it seems to be feasible.

Is there already such software exist?

What do you think?

domo ai avatars vs leiapix vs did for socials

so i was tired of my old selfie on linkedin. tried leiapix avatar depth shot. looked neat but more like a gimmick.
then i tried did avatars. decent but stiff, kinda uncanny.
finally i uploaded into domo ai avatars. typed “cartoon, anime, cyberpunk.” instantly got 15 avatars that looked like me but stylized.
with relax mode unlimited i spammed until i had avatars for linkedin, discord, twitter, even tiktok. friends legit thought i paid commissions.
so yeah leiapix = gimmick, did = stiff, domo = versatile pack.
anyone else rotate domo avatars??

Github Profile Card Iframe Generator - showcase your github profiele on any webpage!

Hello Everyone!

Lately I wanted to integrate some kind of a "github profile card" on my portfolio website but I havent found anything that fit my needs.

So I quickly created a new (open source) tool to do do that!

It generates a ready to paste iframe code that should work on any webpage and I tried to make it as configurable as possible while keeping it simple.

It shows your basic user infos, pinned repositories as well as a simpe activity chart.

Let me now if this makes sense and feel free to give me any feedback to improve this.

Thinking about building an open-source multi-business form & marketing system — feedback or collaborators welcome

Hey everyone,

I’m in the idea stage of designing an open-source system that could run on a server or mini-PC and support multiple businesses with their own logins.

Here’s the concept:

A custom form builder for small businesses to create check-in or data-collection forms (with fields like name, phone number, signature, etc.).

When a customer enters their name and phone number, the system checks the database:

If they already exist and it’s been fewer than X days (configurable), it shows a quick end message and logs the visit.

If not, it displays the full form to complete.


Completed forms automatically generate a PDF and optionally save to Google Drive, OneDrive, Dropbox, or a personal server.

On the backend, each business can manage multiple forms.

I also want to add a marketing module to send SMS or email reminders — for example, follow-ups to customers who haven’t checked in for X days, or periodic promotional messages.


This is still just a concept I’m planning to start — mainly because a family member’s small business needs something like this that’s self-hosted, affordable, and flexible.

If anyone has feedback, technical suggestions, or wants to collaborate, I’d really appreciate it. Also, if there’s already something similar out there, please share — I’d rather build on top of existing tools than reinvent the wheel.

Self‑hosted meeting trannoscription bots (Microsoft Teams + Google Meet): private deployment, data governance, and our OSS architecture (Apache‑2.0)

I wanted to share what I've been building for the past year and why it might matter to the open‑source community. Meeting notetakers like Otter, Fireflies, and Recall send your company's conversations to their cloud. No self‑host option. No data sovereignty. An API‑first, open‑source, microservice‑based, scalable stack is the natural response here. Notetakers are shiny UI products—not what tech teams need. What's needed is a simple API, not another interface.

What I built: An open‑source meeting trannoscription stack (Apache‑2.0) that you can fully self‑host. Send a bot to Microsoft Teams or Google Meet, stream trannoscripts in real time, and keep everything on your infrastructure. It's a data access layer you can feed into AI—without third‑party servers touching your meetings.

**The journey so far:**

I shipped v0.1 back in April 2025—Google Meet only, and within days the #1 request was Microsoft Teams support.

The problem wasn't just "add Teams." The bot architecture was Meet‑specific. I couldn't bolt Teams onto that without creating a maintenance nightmare.

So I rebuilt it from scratch to be platform‑agnostic—one bot system with platform‑specific heuristics. Whether you point it at Google Meet or Microsoft Teams, it just works.

Then in August, I launched a hosted service (for folks who want the easy path). That's when reality hit. Real‑world usage patterns I hadn't anticipated:

* **Predictable bot behavior and orphan bots:** bots missing leave signals, sitting in "ghost mode," needing cleanup
* **Trannoscription model parameter tuning:** scaling without noticeable quality or latency drops (segment length, VAD thresholds, beam/temperature)
* **API validation and limits:** so misuse can't break pipelines (schemas, string/size caps, rate limits)

I spent the last few weeks hardening the system for v0.6. Today it scales well—clean dashboards, no user‑reported surprises—and the same codebase powers private deployments.

**Today, v0.6 is live:**

\- Microsoft Teams + Google Meet support (one API, two platforms)
\- Real‑time trannoscript streaming (data access layer for AI)
\- Apache‑2.0 licensed (fully open source)

Meeting trannoscripts never leave your infrastructure, so companies are starting to build internal tools for internal meetings management on top of the stack.

**Technical details for the curious:**

* **ASR model:** Whisper (open source, open weights) runs locally. Choose tiny for first run on Mac/Windows; up to large‑v3 on GPU for quality.
* **Architecture:** Microservices (Python/FastAPI + TypeScript bot), all Dockerized
* **Deployment:** One command `make all` on GCP/AWS GPU node or on‑prem (deployment guide in repo)
* **License:** Apache‑2.0 (permissive, commercial‑friendly)

Whisper can also translate in real time if you set output language different from spoken—niche but neat.

Why So Many Open Source Developers Feel Like Frauds

Imposter syndrome is surprisingly common among open source developers, and most feel "not good enough" or are afraid of being criticized. Why should this be so rampant in open source? Are there things that we can do to normalize learning and failure so that we build a more welcoming space?

Let's discuss what works to deal with these feelings, such as prioritizing incremental progress, rewarding small wins, and capitalizing on peer support.

lanparty with iroh (hamachi clone)

Just created release builds for iroh-lan which is a full hamachi clone.

An ephemeral layer 3 network is created sending TCP, UDP and ICMP packages over the iroh quic p2p direct connections. No servers in the loop. Bootstrapping and finding other nodes that entered the network name+password combo via the Bittorrent mainline DHT.


The idea is a no-install hamachi clone without accounts or network creation.

1. start the app

2. enter a network name and password

3. wait for peers to join and see their ip addresses displayed


IP-range: 172.22.x.x

Looking for an Open Source IDE that does NOT have AI integration.

I'm not even sure this exists. I can't even find an IDE that doesn't advertise itself as AI vibe coding no-coding bullshit, but I do not trust that spyware bullshit. Every term I can think of to search for IDEs without AI integration comes up with specifically IDEs marketed as AI powered. Any suggestions greatly appreciated. At this rate Notepad might be the last remaining bastion of non-surveilled coding
