I need a coding font that supports ligatures and does not cost money (open source).

Here are the top open-source, free programming fonts that feature fantastic ligature support:

• JetBrains Mono - Specifically designed for developers by JetBrains. It increases the height of lowercase letters to make code easier to read on small screens and includes clean, subtle ligatures that don't distort code structure. Download it from JetBrains Mono.
• Fira Code - The classic go-to open-source font for coding ligatures. Created by Nikita Prokopov, it features a massive, well-tested set of programming ligatures that turn multi-character operators (like !=, -> , and === ) into crisp, unified symbols. Get it on the Fira Code GitHub Repository.
• Cascadia Code - Developed by Microsoft for Windows Terminal and modern code editors. It supports full programming ligatures and comes with a fun "Cascadia Mono" variant if you ever want to turn ligatures off. Find it via the Microsoft Cascadia Code GitHub.
• Monaspace - An innovative open-source superfamily by GitHub featuring five distinct text textures (Argon, Krypton, Neon, Radon, Xenon). It uses "texture healing" to fix the awkward spacing that monospace fonts usually suffer from when combining certain characters, alongside great ligatures. Explore it at Monaspace GitHub.
• Iosevka - A slender, highly customizable open-source font. It is a narrower (condensed) sans-serif/slab-serif typeface that packs an incredible number of characters and rich ligature sets onto your screen, ideal if you love split-screening code. Check out the Iosevka GitHub.

If you want to narrow this down, let me know:

• What editor or IDE you are using (VS Code, Neovim, JetBrains, etc.)
• Whether you prefer a wide/standard look or a condensed look

Good open-source coding fonts with programming ligatures include:

GitHub GitHubMy recommendations:

1. Fira Code — the safest choice - Free and open source (SIL Open Font License)

• Probably the most recognizable ligature-focused coding font
• Great symbols for =>, !=, ===, <=, ->, //, etc.
• Works well almost everywhere

GitHub1. JetBrains Mono — best everyday readability - Free and open source

• Slightly cleaner and less “decorative” than Fira Code
• Excellent character shapes and spacing for long coding sessions

FontFYI1. Cascadia Code — best if you use Windows - Developed by Microsoft

• Includes programming ligatures
• Has Powerline variants for terminal prompts

GitHubIf I had to pick one default: JetBrains Mono for comfort, or Fira Code if you specifically want the coolest ligatures.

To enable ligatures in editors:

• VS Code: set "editor.fontLigatures": true
• JetBrains IDEs: Settings → Editor → Font → Enable ligatures
• Neovim: depends on your GUI frontend (e.g., Kitty, WezTerm, or a Neovim GUI)

I’d avoid overly decorative fonts for daily work; ligatures should improve scanning without making operators harder to recognize.

Here are the best open-source, completely free programming fonts that include coding ligatures:

• JetBrains Mono : Designed specifically for developers by JetBrains. It features increased height to improve readability, distinctive characters to avoid ambiguity, and clean, subtle ligatures. Available under the SIL Open Font License, you can download it directly from the JetBrains Mono Site.
• Fira Code : One of the most popular and classic choices for developers. It is a monospaced font containing a massive set of programming ligatures for common multi-character combinations (like ->, !==, and =>). It is free and open source on the Fira Code GitHub Repository.
• Cascadia Code : Created by Microsoft for Windows Terminal and code editors like VS Code. It supports full programming ligatures and comes in various weights, plus a non-ligature variant (Cascadia Mono) if you ever want to toggle them off. Get it on the Cascadia Code GitHub Repository.
• Monaspace : Developed by GitHub, this is an innovative family of monospace fonts with "texture healing" (advanced stylistic sets and ligatures that help align uneven character widths gracefully). You can check it out on the GitHub Monaspace Page.
• Victor Mono : A clean, distinct open-source monospaced font that stands out because its italic style is a cursive script. It includes crisp programming ligatures and is available on the Victor Mono Site.

Would you prefer a font with a more traditional look , something ultra-condensed like Iosevka, or help with how to enable ligatures in your specific editor?

Absolutely. Here are some excellent free, open-source coding fonts with programming ligatures:

• JetBrains Mono — Clean, modern, and very readable. It has programming ligatures, multiple weights, and extensive character variants. It's also OFL-1.1 licensed and free for commercial/non-commercial use.
• Cascadia Code — Microsoft's programming font family, with a particularly nice look in Windows Terminal and VS Code.
• Iosevka — Highly customizable and compact, with extensive ligature and glyph customization. Great if you like tweaking your font's appearance.
• Victor Mono — A distinctive programming font with ligatures and a cursive italic style. Nice if you want something less conventional.

My recommendation

If you just want to install one and get coding:

1. Fira Code → best overall ligature experience 2. JetBrains Mono → best readability / modern appearance 3. Iosevka → best customization

For VS Code, for example, Fira Code can be enabled with:

{
  "editor.fontFamily": "Fira Code",
  "editor.fontLigatures": true
}

Fira Code's documentation specifically confirms this configuration.

If you tell me Windows/macOS/Linux + your editor (VS Code, Neovim, IntelliJ, etc.), I can recommend the best one for that setup.

I can give you the exact setup instructions to turn ligatures on for your specific environment.

Absolutely. I’d shortlist these free, open-source coding fonts with programming ligatures:

My recommendation: Fira Code

If you just want to install one and forget about it, I'd pick Fira Code. It was specifically designed around programming ligatures such as ->, =>, !=, ===, <=, and :=, while keeping the underlying source code unchanged.

If you prefer a cleaner, more modern look: JetBrains Mono

JetBrains Mono is my other strong recommendation. It has a slightly taller, very readable appearance and supports OpenType ligatures and stylistic alternatives. It's explicitly free/open source under the OFL-1.1 license.

If you're using VS Code, either works with:

"editor.fontFamily": "Fira Code",
"editor.fontLigatures": true

Fira Code's documentation specifically recommends this configuration.

My ranking:
🥇 Fira Code — best ligatures
🥈 JetBrains Mono — best readability
🥉 Iosevka — best customization
4️⃣ Cascadia Code — best Windows ecosystem fit
