a tiny studio from Tallinn ✨

We makesoftware
that feels friendly.

KosmoNeko is a small software & solutions studio. We build apps, websites and travel-data products — usually with a cat somewhere in the mix.

what we do →

Three things, mostly. We keep the team small and the output stupidly polished.

apps

Native iOS apps that real humans actually want to keep on their home screen.

websites

Marketing sites and web apps that load fast, feel good, and don't lie to you about cookies.

solutions

The custom integrations, dashboards and weird internal tools that grease the rails.
