How We Build

Built right, everywhere

📐

Spec-first

Every feature starts as a game design document before a single line of code. The thinking happens upfront so the building flows.

⚡

Native & cross-platform

SwiftUI for Apple platforms. Tauri and Rust for desktop. Docker and Traefik for self-hosted infrastructure. The right tool for each job.

💰

No subscriptions

One-time purchase or free. Software should be owned, not rented. No surprise price hikes, no features held hostage behind recurring fees.

About

One developer, many ideas

CasaVargas LLC is a solo indie software studio founded by Jon Vargas, based in North Carolina. What started as a passion for building things that feel right has grown into projects spanning Apple platforms, the desktop, and self-hosted infrastructure.

From OneScribe on iOS to DebridDownloader across macOS, Windows, and Linux — every app is built with the same philosophy: spec-first, native-feeling, no subscriptions. When not writing SwiftUI or Rust, Jon works in K-12 IT and is always dreaming up the next thing to build.
