Shared Core, Native UI: The New Blueprint for Performance-Critical Apps

The era of sacrificing platform feel for development speed is ending as a new architecture of systems-level cores paired with thin native UI shells gains traction. While custom UI frameworks like Zed's GPUI offer extreme control, pragmatic examples like Ghostty show that leveraging native toolkits remains the most sustainable path for high-performance software. This shift allows developers to maintain a single source of truth for logic while delivering the true native experience users demand.
