About

Built with Independence & Passion

Jett Studio is an independent software studio obsessed with the small frictions that slow people down every day — the extra clicks, the slow dashboards, the spreadsheets that should have been a button.

We build micro-utilities and focused SaaS tools with the speed of an indie team and the polish of a product company. Each tool is shipped fast, refined in public, and supported directly by its maker.

  • Speed as a feature

    If a tool can't deliver value in three seconds, we haven't finished designing it.

  • Privacy by default

    Local processing first. Minimal data. No aggressive tracking — ever.

  • Elegant & focused

    One job, done beautifully. No bloat, no subscriptions you don't need.
