No — Söhne Mono isn’t listed as a free font. Klim Type Foundry releases it, so licence options and pricing sit on their site.
Söhne Mono is a monospace typeface from Klim Type Foundry.
Söhne Mono is Klim Type Foundry’s monospaced adaptation of Söhne, a typeface channelling the analogue materiality of Akzidenz-Grotesk as seen in the NYC Subway’s iconic Unimark signage. The mono version adds subtle serifs to narrow characters like i, j, and l to preserve Söhne’s characteristically tight spacing within monospace constraints.
A1 features 5 websites using Söhne Mono, including Central, Stripe Dev, and For Good Design Lab. They lean towards Minimal, Serif, and Dark design styles, and they’re most often built with Webflow, Framer, and Next.js.
