DevToolbox is a collection of 51+ beautiful, interactive, client-side web utility tools built for developers, designer, and DevOps engineers. We got tired of bookmarks directories full of heavy, ad-ridden single-purpose conversion sites. So we built a unified, premium hub that runs 100% in your browser. Your data never leaves your device. Key highlights: - 🎨 CSS Suite: Flexbox Visualizers, 3D Cube Studios, Glassmorphism, Keyframe timelines, and Shadows. - ✏️ SVG Designer: 24x24 drawing grids, Bezier curve builders, Flowcharts, and Optimizers. - 📦 Data formatters: JSON collapsible trees, SQL formatters, JSON-to-TypeScript compilers. - 🔒 Security checkers: CSP builders, JWT signing studios. - ⚙️ DevOps and LLM utilities: Prompt Packer directory bundler, Git branch commit graph sandbox, Base64 converter. - 🎵 Audio Synth: Web Audio API virtual keyboard. 100% open-source, zero dependencies, responsive, and completely free.

does the tool actually run entirely in the browser or does anything get sent to a backend? curious about privacy when I'm using it on client code
