# Fira Code font > Fira Mono extended with programming ligatures that draw sequences such as -> and <= as single symbols. Fira Code is a monospaced typeface that extends Fira Mono with ligatures for common multi-character programming sequences; Nikita Prokopov is credited with the extension. Fira Code is a variable font with five weights, Light 300 to Bold 700, and 1,846 glyphs. It is released under the SIL Open Font License 1.1 and suits code editors and terminals. ## Facts - Classification: [Monospace](https://trendhub.net/fonts/category/monospace) - Designed by: The Mozilla Foundation, Telefonica S.A., Nikita Prokopov - License: SIL Open Font License 1.1 (https://openfontlicense.org/open-font-license-official-text/) - Styles: 5 (Light 300, Regular 400, Medium 500, SemiBold 600, Bold 700) - Variable font: Yes (wght 300–700) - Glyphs: 1846 - Character sets: cyrillic, cyrillic-ext, greek, greek-ext, latin, latin-ext, symbols2 - Last updated: 2025-09-16 - Official source: https://fonts.google.com/specimen/Fira+Code - Page: https://trendhub.net/fonts/fira-code - Tagged for: Code, Tech ## About Fira Code Fira Code is a monospaced typeface built on Fira Mono with an added set of programming ligatures. Sequences such as an arrow, a less-than-or-equal sign or an assignment operator are drawn as one joined symbol, and for frequent pairs like two dots or two slashes the ligatures correct the spacing. This is a rendering feature only: the underlying text stays ordinary ASCII characters. The specimen shows a zero with an interior mark, a serifed i, and an l and 1 that are easy to tell apart. Fira Code is a variable font with a weight axis from 300 to 700 and five named weights, Light to Bold; it has no italic. Its 1,846 glyphs cover Latin, Cyrillic, Greek and a symbols subset.

Full text: https://openfontlicense.org/open-font-license-official-text/ ## Where it works - **Code editors**: Ligatures turn multi-character operators into single symbols, so comparisons and arrows read as one token. - **Terminals**: A fixed width with distinct zero, l and 1 keeps command output and paths unambiguous. - **Code in slides and tutorials**: Bold 700 and SemiBold 600 stay readable when a snippet is projected. - **Documentation with Cyrillic or Greek comments**: Both scripts are included, so comments in Russian or Greek keep the same character width. - **Configuration and log viewers**: Five weights let a tool show levels or keys with a heavier weight without leaving the grid. ## Things to know - **No italic**: Fira Code has upright weights only; editors that italicise comments will slant it artificially. - **Ligatures can be switched off**: They are an OpenType feature, so an editor or CSS can disable them and show the plain characters. - **The file content is unchanged**: Ligatures alter only how text is drawn; copying code still gives the original characters. ## FAQs ### Is Fira Code free for commercial use?
