Devium

Devium is a compact menu bar toolkit for developers who want quick utilities without opening a full editor or browser tab. Open Devium from the macOS menu bar, choose a tool, and work inside a small focused panel. It is built for everyday tasks: formatting JSON, converting Unix timestamps, testing regular expressions, translating common data formats, and clearing Xcode cache folders when they get heavy. Tools included: - JSON prettifier and minifier - Unix timestamp converter with local and UTC output - Regex scratchpad with capture groups and replacement output - JSON, YAML, and TOML converter - Xcode cleaner for Derived Data, Archives, Device Support, Simulator Caches, and SwiftUI Previews Devium is designed to stay simple. No account, no cloud sync, no network connection, and no tracking. The Xcode cleaner uses macOS sandbox-safe folder access, so you choose the Developer folder before Devium can scan or clean it.
