Tools for the
Modern Era
OpenToolbox was born from a simple frustration: developer tools should be beautiful, fast, and respect your privacy. No ads. No tracking. Pure utility.
Privacy First
We strictly prioritize client-side processing. Your data (images, code, passwords) rarely leaves your browser.
Lightning Fast
Built with Next.js 14 and optimized for Web Vitals. No bloat, no trackers, just pure utility.
Modern Design
Tools shouldn't look like they were built in 1999. We use clean, modern aesthetics for a better experience.
Built for Everyone
Whether you are debugging an API or optimizing your next creative project.
Software Engineers
Format JSON, SQL, and decode JWTs without fear of data leaks.
Designers
Generate CSS gradients, box-shadows, and optimize images.
Privacy Advocates
Generate secure passwords and UUIDs entirely offline.
Mobile Developers
Test deep links and generate QR codes for app downloads.
Support our Mission
OpenToolbox is and will always be community-driven. Your support helps us cover hosting costs and allows us to build even more free tools for everyone.
Fuel the Development
OpenToolbox is free, open-source, and devoid of annoying ads. If these tools saved you 5 minutes today, consider buying me a coffee!
