Capsule started as a basic HTTP server to teach myself Rust.Then I kept going, and it turned into the first full-stack thing I've fully shipped: a Rust/Axum server, a Rust CLI, an Android app (my first, same story as the Rust one), and a fully featured web UI. It quickly grew as I realized I could solve my file transfer problem by turning a basic webserver into an actual daily use tool.Entire project is open source, code can be found at: https://github.com/withcapsule/Would love to hear anyone's thoughts on this.
