About Dev Toolkit
Dev Toolkit is a collection of free online developer tools that run entirely in your browser. No data is ever sent to a server. No signup required. No tracking beyond anonymous page analytics.
Every tool — from JSON formatting to Base64 encoding to regex testing — executes client-side using standard browser APIs. Your data stays on your device at all times.
The site is built with Next.js, TypeScript, and Tailwind CSS, deployed as static pages on Cloudflare's edge network for fast loading worldwide.
Privacy
We use Google Analytics for anonymous page view tracking. We do not use cookies for tracking, do not collect personal information, and do not store any data you enter into our tools.
