GitNub is a Chrome-based free developer tool designed to enhance your GitHub experience. This tool aims to prevent common mistakes like accidental merges or merging to the wrong branch. It provides a structured approach to define your per-repository workflow using fields with regex values for customization.

With GitNub, you can easily set up rules such as defining the target branch, source branch patterns, and merge types. For instance, specifying TO:`main` FROM:`^DEV` TYPE: `squash` ensures that only the squash merge option is available when merging a pull request from a branch matching the pattern ^DEV into the main branch. This tool streamlines the workflow and improves the accuracy of your GitHub operations.
