Fontjoy

Fontjoy is a web-based font pairing generator for designers, web developers, and marketing teams who need quick, compatible typography for websites, prototypes, and graphics.

Key capabilities include:

• One-click pairing generation using deep learning to suggest fonts that share a common theme while maintaining pleasing contrast
• Lock and Edit controls to keep a preferred font in place, then refine the remaining suggestions by manually selecting alternatives
• Contrast slider to tune results from more similar pairings to higher-contrast combinations
• Live preview text with editable sample copy to evaluate headings and body text together

Pricing: Free.

What makes it notable: all recommendations come from Google Fonts, so the suggested typefaces are free for web use without extra licensing work. The project also shares implementation details publicly via GitHub, which is uncommon among font pairing tools.
