15 Best Free Fonts Alternatives to SF Mono
Apple’s SF Mono ships free with macOS and Xcode, but it never made it to the web as a proper font file you can install anywhere else, which sends a lot of developers and designers looking for a free monospace font that captures the same clean, technical feel. The good news is that Google Fonts has a genuinely strong bench of coding fonts built for exactly this job: crisp letterforms, clear distinction between similar characters like 1, l, and I, and enough weights to handle everything from a terminal theme to a portfolio site’s code blocks. The fonts below cover that range, from near-drop-in replacements to options with a bit more personality for branding work that wants to nod at code culture.

JetBrains Mono
console.log('Hello, world');
JetBrains Mono
Built by JetBrains for its own IDEs, this is probably the closest thing to a spiritual successor to SF Mono in terms of intent: it was designed specifically to reduce eye strain during long coding sessions. The letterforms are slightly taller than average, which helps readability at small sizes in dense editor windows, and the italics are genuinely slanted rather than just obliqued. It pairs naturally with a humanist sans like Inter or Work Sans in developer documentation.
- Language support: Latin, Latin Extended, Cyrillic, Cyrillic Extended, Greek, Vietnamese
- Styles: 16 styles (8 weights plus italics)
-
Fira Code
⚠ Font Specimen: invalid or missing font nameFira Code’s claim to fame is programming ligatures, the way it visually merges character combinations like => or !== into single glyphs when a code editor supports them. That makes it a favorite for screenshots of clean-looking code, though it’s worth turning ligatures off if your audience finds them distracting. Outside of that feature, the underlying letterforms are calm and evenly spaced, based on the earlier Fira Mono.
- Language support: Latin, Latin Extended, Cyrillic, Cyrillic Extended, Greek, Greek Extended
- Styles: 5 weights (Light to Bold)
-
IBM Plex Mono
Compiling project... build successful
IBM Plex Mono
IBM commissioned Plex Mono as part of a full type system meant to replace Helvetica across its brand, and that corporate discipline shows in how measured and well-balanced every character feels. It has a slightly warmer, more humanist touch than SF Mono, with subtle curves that keep long stretches of code from feeling too mechanical. Because it belongs to a full family with matching sans and serif styles, it’s an easy choice when you need monospace text to sit alongside body copy from the same type system.
- Language support: Latin, Latin Extended, Cyrillic, Cyrillic Extended, Vietnamese
- Styles: 14 styles (7 weights plus italics)
-
Roboto Mono
git commit -m 'fix: resolve edge case'
Roboto Mono
As the monospace companion to Android’s default typeface, Roboto Mono is everywhere in technical documentation and developer tools, which makes it a safe, familiar pick. It reads as neutral and unfussy at body-copy sizes, though some of its rounder details can blur slightly when set very small on low-resolution screens. It’s a dependable match for any project already using Roboto for its interface text.
- Language support: Latin, Latin Extended, Cyrillic, Cyrillic Extended, Greek, Vietnamese
- Styles: 14 styles (7 weights plus italics)
-
Source Code Pro
function calculateTotal(items) {
Source Code Pro
Adobe designed Source Code Pro to sit alongside Source Sans Pro, and it carries the same sturdy, slightly condensed practicality. It’s a workhorse rather than a personality font: legible at nearly any size, comfortable in terminal emulators, and unlikely to draw attention to itself in a syntax-highlighted code block. That restraint is exactly what makes it a solid default for technical blogs and API documentation.
- Language support: Latin, Latin Extended, Cyrillic, Cyrillic Extended, Greek, Greek Extended, Vietnamese
- Styles: 16 styles (8 weights plus italics)
-
Inconsolata
return { status: 200, data: response };
Inconsolata
One of the earlier open-source monospace fonts built specifically for code, Inconsolata has a narrower, more compact rhythm than most of its modern peers. That tighter spacing makes it useful in situations where horizontal space is tight, like narrow sidebars showing snippets or mobile-friendly code previews. It can look a touch thin at regular weight on lower-resolution displays, so pairing it with a slightly heavier weight for headings helps.
- Language support: Latin, Latin Extended, Vietnamese
- Styles: 8 weights (Extra-Light to Black)
-
Space Mono
ERROR 404: PAGE NOT FOUND
Space Mono
Space Mono trades pure utility for character, with quirky curves and a retro, slightly nerdy feel borrowed from vintage electronics and early computer terminals. It’s less suited to dense paragraphs of production code and much better suited to branding moments: a startup’s logotype, a 404 page, or a hero section that wants to look technical without being sterile. The bold weight in particular has a punchy, poster-like presence.
- Language support: Latin, Latin Extended, Vietnamese
- Styles: 4 styles (2 weights plus italics)
-
Ubuntu Mono
sudo apt-get update && upgrade
Ubuntu Mono
Part of the Ubuntu type family, this font carries the same rounded, friendly personality as its sans-serif sibling, which makes it feel a little warmer and less clinical than SF Mono. It works well in terminal-themed designs or Linux-adjacent branding where a touch of approachability is welcome. At very small sizes some of its rounder curves soften slightly, so it’s better suited to comfortable reading sizes than tiny footnotes.
- Language support: Latin, Latin Extended, Cyrillic, Cyrillic Extended, Greek, Greek Extended
- Styles: 4 styles (2 weights plus italics)
-
PT Mono
npm install --save-dev eslint
PT Mono
PT Mono has a slightly formal, almost typewriter-adjacent structure that gives it a bit more gravity than typical coding fonts. It suits editorial contexts that want to reference code or data without leaning into a purely technical aesthetic, such as a magazine feature discussing software. Its even stroke weight keeps long strings of numbers and symbols easy to scan.
- Language support: Latin, Latin Extended, Cyrillic, Cyrillic Extended
- Styles: 1 weight (Regular)
-
Cousine
if (isValid) { proceed(); }
Cousine
Metrically compatible with Courier New, Cousine was built as a clean, modern replacement for that old typewriter standard rather than as a direct SF Mono clone, but it shares the same no-nonsense clarity. It’s a good pick when a project needs a monospace font that feels neutral and slightly old-school rather than distinctly modern. Documentation and plain-text-style layouts suit it well.
- Language support: Latin, Latin Extended, Cyrillic, Cyrillic Extended, Greek, Greek Extended, Hebrew, Vietnamese
- Styles: 4 styles (2 weights plus italics)
-
Anonymous Pro
Terminal output: connection established
Anonymous Pro
Anonymous Pro was designed with print journalists and coders in mind, aiming for a monospace font that stays legible in both a text editor and a printed page. Its distinguishing marks, like a dotted zero, make it a practical choice anywhere ambiguity between characters would cause real problems, such as printed credentials or configuration files. It has a slightly narrower footprint than some newer coding fonts, which suits dense listings.
- Language support: Latin, Latin Extended, Cyrillic, Greek
- Styles: 4 styles (2 weights plus italics)
-
DM Mono
{ theme: 'dark', fontSize: 14 }
DM Mono
DM Mono leans more toward editorial and interface design than pure code display, with a lighter, more refined stroke than most fonts on this list. It reads less like a terminal font and more like a typewriter reinterpreted for modern screens, which makes it an appealing choice for portfolio sites, data-driven dashboards, or captions labeling technical diagrams. The lighter weights can lose definition at very small sizes, so keep it comfortably readable rather than tucked into fine print.
- Language support: Latin, Latin Extended
- Styles: 6 styles (3 weights plus italics)
-
Red Hat Mono
curl -X GET https://api.example.com
Red Hat Mono
Part of Red Hat’s open-source type system, this font has a crisp, contemporary structure that feels closer to current interface design trends than some of the older coding fonts on this list. It sits comfortably next to Red Hat Text or Red Hat Display when a brand wants its code samples and body copy to feel like one coherent family. The letterforms stay clean and open even at smaller sizes, which suits UI labels as much as code blocks.
- Language support: Latin, Latin Extended
- Styles: 10 styles (5 weights plus italics)
-
Martian Mono
SYSTEM STATUS: ONLINE
Martian Mono
Martian Mono goes further into stylized, retro-futuristic territory than the average coding font, with unusually shaped characters that evoke old computer displays and sci-fi interfaces. It’s not the font to reach for in a dense production codebase, but it excels in headings, badges, or branding for developer tools that want a bold, distinctive identity. Use it sparingly and let a more neutral mono handle the actual body text.
- Language support: Latin, Latin Extended, Cyrillic, Cyrillic Extended
- Styles: 8 weights (Thin to Extra-Bold)
-
Spline Sans Mono
export default function App() {
Spline Sans Mono
The monospace counterpart to Spline Sans, this font has a clean, slightly geometric structure that feels current without chasing novelty. It’s well suited to modern developer portfolios and SaaS product interfaces that want their code snippets to look as polished as the rest of the design. Consistent spacing and open counters keep it legible even when set fairly small in a code editor mockup.
- Language support: Latin, Latin Extended
- Styles: 10 styles (5 weights plus italics)
Pairing and using monospace fonts on the web
Monospace fonts work best as an accent rather than the voice of an entire page. Reserve them for code blocks, technical labels, or small branding flourishes, and let a sans-serif or serif handle long-form reading.
When pairing, match the mood first. A geometric sans like Space Grotesk suits a quirky font like Space Mono, while a neutral workhorse like IBM Plex Sans sits naturally beside IBM Plex Mono.
Test legibility at the sizes you’ll actually use. Some of these fonts hold up beautifully in a full-size code editor but soften at the tiny sizes used for badges or footnotes, so check both extremes before committing.
Any of these free Google Fonts can stand in for SF Mono without asking readers to install anything extra, and most cover the full range from body-size code to bold display use. Pick based on the mood you want, whether that’s the clinical precision of Roboto Mono or the retro character of Space Mono, and the rest of the interface will follow its lead.
