Gemtracker

What it does

GemTracker gives Ruby devs full visibility into dependencies in seconds. Just run it on any Gemfile.lock to see: • Outdated gems & version differences • All CVEs with severity and fixes • Forward & reverse dependency trees • Health scores (Healthy/Warning/Critical) • Fuzzy search + exports (text/CSV/JSON)No setup. Combines bundle outdated, security scans, and impact mapping in one fast TUI — no more switching tools.

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
