Here you’ll find practical free tools for homelab operators and self-hosters — small, focused browser utilities that solve one specific problem and get out of the way. No account required, no data sent to any server. Everything runs client-side, right in your browser. 🔒

Each tool is built around three rules: simple (clear input, predictable output), fast (instant results, no backend wait), and privacy-first (your data stays on your machine — open DevTools and verify it yourself). These are the kind of practical free tools for homelab workflows that I build when I need something and a good solution doesn’t exist yet.
