DevHub is an offline utility app for macOS that collects many small developer tools into a single application. The idea is to replace the habit of bouncing between web-based converter sites, terminal one-liners, and scattered utility apps. Everything runs locally on your Mac and nothing is sent to a server. The toolset covers a wide range of everyday tasks. Text and encoding tools include Base64 conversion, URL encoding and decoding, JSON formatting, HTML formatting and minification, JWT parsing, regex testing, and text case conversion. Image tools cover OCR (reading text from images), EXIF metadata viewing, watermarking, background filling, ICO file conversion, and color extraction. Security and network tools include hash generation, RSA key generation, Basic Auth generation, and a built-in API request tool for testing HTTP calls. There are also time, date, and system utilities such as timestamp conversion, a crontab generator, a chmod calculator, random port generation, and device information. The app requires macOS 14 or later. It is available through the Mac App Store and is under active development, with the stated goal of shipping updates weekly and eventually reaching more than 100 individual tools. DevHub supports URL Scheme integration, which means you can trigger a specific tool by opening a URL. This works from the terminal, from a browser address bar, or from automation tools like Raycast. For example, opening devhub://qrCodeEventGenerator launches directly to the QR code event generator inside the app. According to the repository, the app does not collect, store, or transmit personally identifiable information, which is a stated design priority for users who work with sensitive data locally.
