I Built 35+ Developer Tools That Run Entirely in Your Browser

Hey DEV community! 👋

I recently launched DevBox, a collection of 35+ free developer tools that all run locally in your browser.

Why I Built This

I was frustrated with online tools that:

• Required signups just to format some JSON
• Sent my data to unknown servers
• Were cluttered with ads and slow to load

So I decided to build my own solution.

What Makes DevBox Different

🔒 Privacy-first
All tools run entirely in your browser. Your data never leaves your device. No servers, no tracking, no data collection.

⚡ No signup required
Just open and use. No accounts, no emails, no passwords.

🛠️ 35+ Tools Included

Here are some of the most popular ones:

• JSON Formatter & Validator - Beautify, validate, and minify JSON
• Base64 Encoder/Decoder - Encode and decode Base64 strings
• JWT Decoder - Decode and inspect JWT tokens
• Password Generator - Generate secure random passwords
