About dev bench
dev bench is a growing collection of developer utilities — the kind of small tools every engineer ends up googling once a week.
Every tool runs entirely in your browser. Your input never leaves your machine — no upload, no logging, no server-side processing. That makes dev bench safe to use with API responses, JWTs, internal SQL, and other sensitive snippets.
The site is funded by Google AdSense so the tools can stay free. We appreciate your support.
