Like most devs, I use tools for Base64, JSON formatting, JWT decoding, and Cron parsing every day. I got tired of Googling "Base64 decode" and pasting sensitive data into random websites, so I built Devly.

I just released v2.0, which adds a full CLI. It’s designed for macOS workflows and handles everything locally/offline.

What makes it different:

It’s a CLI bridge that delegates processing to a native macOS app. This keeps the logic consistent between the GUI and the terminal while ensuring everything stays off the cloud.

Examples of what you can do:

devly base64 "Hello World"

cat data.json | devly jsonformat > pretty.json

devly cron "0 9 \* \* 1-5" (Explains the cron expression in plain English)

echo "test" | devly base64 | devly hash

Installation:

brew install aarush67/tap/devlycli

Full list of 50+ tools: [https://devly.techfixpro.net/docs/tools/](https://devly.techfixpro.net/docs/tools/)

Technical Note: The CLI requires the Devly app (available on the Mac App Store) to run the processing headless. I built it this way to leverage native Swift performance and keep the logic centralized.
