What developer tool do you wish existed for free?

I built STB Tools because I kept hitting paywalls and login walls for basic utilities like JSON formatting and URL encoding.

Curious — what tools do YOU use daily that are either paid, full of ads, or require signup for no reason?

I'm actively building new tools and would love to know what the community actually needs. Drop your suggestions below 👇

Current free tools at softwarethatbenefits.org:

🔗 URL Encoder / Decoder

🔧 JSON Formatter

🔐 Base64 Encoder

🪙 JWT Decoder

🔍 Regex Tester

🎨 Color Converter
