I built a tool that tells you what developers are actually learning — not just Twitter hype

Every few months there's a new "hottest technology" trending on Twitter. Half the time it's just noise from a few loud accounts. I wanted to know what developers are actually gravitating toward — based on what they're building, writing, and discussing. So I built trend-radar : a Python CLI that pulls real signals from three sources and ranks them by weighted growth velocity. The Problem Tech hype is asymmetric. A single viral tweet can make a niche tool look dominant. Meanwhile, slow-burning technologies that millions of developers are quietly adopting get ignored. The only way to cut through this is to look at behavior, not opinion: What are developers actually building ? (GitHub) What are they writing about ? (Dev.to) What are they discussing ? (Hacker News) What trend-radar does pip install trend-radar trend-radar It fetches trending data from all three sources in parallel, normalizes the signals, weights them (GitHub 50%, Dev.to 30%, HN 20%), and outputs a ranked table: Technology
