Code Red - GitLab Merge Warning is a Chrome extension designed to enhance the visibility of GitLab's merge button, transforming it from a standard blue to a striking red with high-contrast yellow text and warning emojis. This visual modification aims to prevent accidental merges by making the button more noticeable, thereby giving developers an extra moment to verify their actions before proceeding. The extension works seamlessly on both GitLab.com and self-hosted instances, automatically detecting dynamically loaded buttons while preserving the original button text.

This tool is particularly beneficial for developers and teams who work on critical production code or those who have encountered issues with accidental merges in the past. With a focus on privacy and safety, Code Red does not collect any data, perform tracking, or make network requests, ensuring a secure user experience. As an open-source solution, it modifies only the button appearance locally, making it a practical addition to any developer's toolkit.
