OpenToolBox is a free, privacy-focused suite of developer tools where every operation happens 100% client-side in your browser. Your code, documents, and data never leave your computer. Why This Matters: As developers, we constantly upload sensitive data to random websites contracts to PDF signers, proprietary code to JSON validators, personal documents to image converters. OpenToolBox eliminates this risk by processing everything locally.

Hey Product Hunt community! 👋 After years of frustration with ad-ridden, privacy-invasive tool websites, I built OpenToolBox a complete toolbox that runs entirely in your browser. Every tool, from PDF signing to JSON formatting, processes your data locally. Nothing is uploaded. No tracking. No ads. Just clean, fast tools for developers who care about privacy. Why this exists: Last month I watched a colleague upload a sensitive company contract to a random PDF signing site. That moment made me realize: we shouldn't have to choose between convenience and privacy for basic developer tasks. What makes it different: • 100% client-side processing • 25+ tools in one clean interface • Zero data leaves your computer • Free forever, no "premium" upsells Try the viral combo: Sign a PDF without uploading it Format some JSON instantly Convert an image locally Perfect for: developers, designers, students, security-conscious professionals. Would love your thoughts on the tools and implementation! What essential tool are we missing?
