The idea sounds simple, but it addresses a real problem. If you want to know what developers think about a new framework, what founders are saying about a startup, or how people are reacting to a product launch, most of that information never ends up in articles. It gets buried in comment sections, issue threads, podcasts, and social media posts. Last30Days pulls those discussions together and ranks them using engagement signals such as upvotes, likes, comments, and prediction market activity. (GitHub)<br>What makes the repository interesting is that it is focused on a specific workflow rather than trying to be a general AI platform. It is essentially an attempt to create a search engine for public opinion and recent discussion, which explains why it recently reached the top of GitHub Trending. (LinkedIn)
2. Chrome DevTools MCP
Repo: https://github.com/ChromeDevTools/chrome-devtools-mcp<br>Chrome DevTools MCP gives coding agents direct access to Chrome DevTools, making it easier to inspect pages, debug issues, and interact with browser sessions programmatically. The repository has been one of the more discussed developer tools on GitHub Trending because it connects AI coding agents with tooling developers already use every day. (GitHub)
