Where do these emoji shortcodes work?

The colon-wrapped shortcode form such as :rocket: is used by GitHub (issues, pull requests, comments and markdown), Slack and Discord, plus many static-site and chat tools. The exact set supported varies slightly between platforms.

Why use a shortcode instead of pasting the emoji directly?

Shortcodes are plain ASCII text, so they are easy to type, search and review in code or markdown, and they render consistently across platforms that support them rather than depending on your keyboard or device's emoji picker.

Is anything I type or copy sent to a server?

No. The full list, the search and the copy-to-clipboard all run entirely in your browser — nothing you type is uploaded anywhere.
