A feature-rich offline application, is meticulously crafted to support developers in their daily tasks while ensuring the utmost security of their data
DevHub is a native macOS app that puts about 100 small developer utilities in one window, covering JSON and Base64 formatting, JWT parsing, regex testing, hashing, QR codes, image tools and API requests. It is for macOS developers who currently bounce between web tool sites and shell one-liners for these jobs.
It is a native SwiftUI app on macOS 14+ rather than a web view wrapper, which matters for a tool you open dozens of times a day. The URL scheme (devhub://qrCodeEventGenerator and similar) gives every tool a stable entry point, so Raycast and terminal commands can open a specific utility without UI navigation. The repo ships its privacy policy and terms alongside the code, so the local-only claim is written down somewhere you can check.
'Offline' is more accurate as 'your input stays on the machine' than 'no network': the API Request tool and NPM Stat reach out to the network by design. It is macOS only, so nothing here helps a team that works on Linux or Windows. The README promises weekly releases, but the last push was in April 2026, about five months before this evaluation, and the feature list reads as a checklist of one-off converters with no visible test directory, so the correctness of individual tools can't be verified from the repo alone.
