Lobe Chat
LobeChat is a open-source, extensible (Function Calling), high-performance chatbot framework.It supports one-click free deployment of your private ChatGPT/LLM web application.
Project mention: OSS Alternative to Open WebUI – ChatGPT-Like UI, API and CLI | news.ycombinator.com | 2025-11-03How does this compare to the already established open source solutions such as Chatbox (https://github.com/chatboxai/chatbox), or Lobechat (https://github.com/lobehub/lobe-chat)?
Been using both, like Chatbox for how snappy it is, but is local only, vs Lobechat which allows you to setup centralized host to have shared host across client but feels a bit clunkier.

- Project mention: How Preply improved INP on a Next.js application (without React Server Components and App Router) | dev.to | 2025-02-13
It doesn’t sound like a huge list. Still, the 300 React components and their sub-children take significant time to be added to the DOM on a slow smartphone (please note: we are speaking about the React->DOM reconciliation that adds all the new elements to the DOM, not the render step itself). We used React Virtuoso since it was already used in our front-end projects, but virtualization libraries are all quite similar.

Welcome to New Expensify: a complete re-imagination of financial collaboration, centered around chat. Help us build the next generation of Expensify by sharing feedback and contributing to the code. (by Expensify)
Project mention: What We Talk About When We Talk About Sideloading | news.ycombinator.com | 2025-10-28Tangent about open source development
As a person that tried the Pine64 ecosystem and not being able to will drivers/C++ apps into existence (like I can with web/cross platform), I did not contribute much other than buying the device/doing some videos on YT. (I bought: PP, PPP, PineBook, PineNote, PineTab)
It depended on few people working on it eg. through Discord communities
Anyway point is I saw Expensify I think they have these GitHub PRs which have $ values on them, would be interesting to take that approach, just pay for it literally eg. a GoFundMe for a feature.
ex. https://github.com/Expensify/App/issues/73681
