About DevUtils

DevUtils is a macOS app that bundles developer tools such as formatters, converters, encoders and a JWT debugger into one interface that works offline. Its site lists 47+ tools.^{Source [3]}^{Source [4]}

It launched at $9 as a one-time purchase and reached the top of Hacker News for a few hours, which brought Dinh's first online revenue. He later called it nearly feature-complete and running on autopilot.^{Source [2]}^{Source [5]}

Dinh's X bio lists DevUtils at $5K a month in October 2026, a self-reported figure.^{Source [6]}
