Reviews

What developers are saying.

"Switched to Fira Code with ligatures the moment I found this. Reviewing PRs on GitHub finally doesn't hurt my eyes."

Marco D.
Backend Engineer

"Bumped the line height to 1.7 and dropped the size to 13px. Diffs are so much easier to scan now."

PK
Priya K.
Frontend Developer

"Small extension, does exactly one thing well. JetBrains Mono everywhere, including GitHub, at last."
