Most free tool sites upload your files, gate features behind accounts, and scatter tools across ad-covered pages. utilisio puts 55 tools (converters, dev, text, design, SEO) in one place — no signup, no limits. Almost everything runs 100% in your browser: files never leave your device, and per-tool trust signals show exactly what stays local. Add a ⌘K command palette, instant lazy-loaded pages, and a customizable terminal-style UI in EN/FR.
