About DevPocket

Last updated: 2026-10-09

DevPocket is a pocket-sized toolbox for developers, students and anyone who works with data: format JSON, test a regex, convert a timestamp, generate a secure password. Every tool runs entirely in your browser, so what you paste never leaves your device.

DevPocket is one of five free, ad-supported sites built by Masons-coding. We keep them fast, accessible and useful on every screen from a small phone to a huge monitor. Nothing here asks you to sign up.
