My laptop filled up again. Cursor and Claude Code had left git worktrees on disk, with node_modules and target folders still in them. I wrote lysosome to list those and delete the safe ones.
lysosome scans dormant git worktrees, idle build artifacts, package caches, local models, Docker, and Xcode data. lysosome clean is a dry run until you pass --yes or type y, and deletes go to the Trash.
Here's a confession: I can't keep up with release notes. Claude Code, Cursor, Windsurf, Gemini CLI, Copilot CLI, Codex CLI, Kiro – they're all shipping at breakneck speed, and every week there's a new version with features that could change how I work. But reading through changelogs? My eyes glaze over by paragraph two. I'm a visual person. I need to see what changed, not read a wall of text about it.
That frustration is why I built Havoptic.
Havoptic is an open-source visual release tracker for AI coding tools — Claude Code, Cursor, Windsurf, Copilot, and more. Built with React on Cloudflare because I got tired of reading four different changelogs to find out what changed each week.
