Github Trendings

Bitchat

A decentralized peer-to-peer messaging app that operates over Bluetooth mesh networks—no internet, servers, or phone numbers required. The project is publicly licensed and was launched by Jack Dorsey, former Twitter co-founder. Don’t hesitate to check out the whitepaper.

TradingAgents

Stonks! Unleash your inner wannabe billionaire and watch your AI agents battle it out to analyze the market.

TradingAgents is a multi-agent trading framework designed to mirror the dynamics of real-world trading firms. I wouldn’t risk my own money with it, but it’s one of the most mature AI agent projects I’ve seen in a while.

Rustfs

A high-performance distributed object storage system built in Rust.
It aims to be an alternative to MinIO, which switched its license to the invasive GNU AGPL v3 a few years ago.

Rustfs offers high performance, a distributed architecture, S3 compatibility, and data lake support. However, it is still under rapid development and should not be used in production environments yet!

FossFlow

An open-source web app for creating isometric diagrams. Built with React and a fork of the Isoflow library, it works entirely in your browser, with offline support and local storage. You can try it in online !

AI might be slowing down Open Source developers instead of speeding them

Read the latest study from METR measuring the impact of early-2025 AI on experienced open-source developer productivity.

📝 One of the developers included in the studies shares insightful comments about the experiments and how the time he gained thanks to the AI was often lost scrolling through other stuff while the prompt completed. Link Here

📝 I tend to rely heavily on AI for development. I switched to Cursor last December, and I feel that my ability to build proofs of concept has drastically improved. I don’t think it adds much value for complex production projects where you need to be very cautious, but for everything else, it’s awesome.

Huawei’s star AI model is built on burnout and open-source theft, whistleblower claims

On July 5th, the True-Story-of-Pangu GitHub repository was published as a whistleblower report detailing the intense and allegedly plagiaristic development of Huawei’s flagship LLM, Noah Pangu.
