Building a pair-programming app in public with Rust
summary
An open‑source pair‑programming app called hope is built in Rust with a Go backend, Redis pub/sub, Tauri/iced/wgpu native UI and screen_capture_kit_rs for capture; it offers remote control, drawing and one‑click calls and serves 4K by default. Major work: switch from webviews to native Rust, choose H.264 and tune WebRTC (enabled screencast flag) to push <100 ms round trip on good networks. Repo is self‑hostable and cross‑platform (macOS, Windows, Linux coming).
