Beyond the horizon

A few things
we’re curious about.

New tools, unfamiliar languages, unexpected algorithms. A few ideas we’d like to explore by making something useful—or simply worth playing with.

  1. A personal finance app.

    A calmer way to understand where your money goes, and what comes next.

    Designed to work entirely offline, syncing with family nearby through a shared ledger.

    Local sync · Bluetooth · Blockchain & consensus
    Work in progress

  2. A world in a jar.

    Plant a tiny ecosystem. Change the conditions. See what finds a way to live there.

    Artificial life · Cellular automata
    Idea

  3. An instrument that listens back.

    Hum a phrase or tap the table. Hear an instrument answer with something you didn’t quite expect.

    Generative sound · Signal processing
    Idea

  4. Places we keep.

    Capture a place you love. Keep a little 3D memory you can look around again.

    Spatial capture · Gaussian splatting
    Idea

  5. What if it all fit?

    A trip, a move, a crowded week. Set the limits, change one thing, and see what becomes possible.

    Constraint solving · Search algorithms
    Idea

Behind the projects

One studio.
No single direction.

Osavus is an independent software studio in Estonia. We follow the ideas that stay with us: practical tools, thoughtful details, and the occasional journey far from everyday life.
