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.

Love how everything runs client-side with zero dependencies, that privacy-first approach is a really thoughtful choice for a dev toolkit. Clean layout too.

How does this stay free with 51 tools hosted client-side, and are there any plans to add paid tiers or team collaboration features down the line?

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
