What is one?

One is a React framework that lets you build apps for both web and mobile platforms using almost entirely shared code. Instead of writing separate codebases for iOS, Android, and the web, you write your app once and deploy it everywhere. It uses Vite (a popular build tool) as a plugin to handle the heavy lifting, so setup is straightforward. The core idea is to eliminate the friction of cross-platform development. Normally, building an app for multiple platforms means managing different projects, different build processes, and duplicating logic across codebases. One compiles your single codebase down to whichever platform you're targeting, handling the platform-specific differences automatically behind the scenes. You focus on your app's logic and UI, and the framework handles getting it to run on web browsers, iPhones, and Android devices. This would appeal to startup founders or teams who want to move fast and don't have the bandwidth to maintain three separate codebases. A small team could ship a web version and a mobile app from a single React codebase, cutting development time and keeping code in sync. Larger teams shipping across platforms would benefit too, since shared code means fewer bugs and faster feature rollouts. The README is sparse and points to their documentation website for details on how to actually use it. The project is written in TypeScript, which means developers get type safety and better tooling support as they write their code.
