We build tools for music — and the things we find interesting.
An independent studio shipping our own products — used by listeners, fans, and teams around the world.
[email protected] ↗Hernas is a small, self-funded software studio on the Baltic coast of Estonia. We design, build, and run our own products end to end — no clients, no investors, long horizons.
Most of what we make lives at the intersection of music and software. The rest is simply whatever we wish existed.
