Zed

High-performance code editor built in Rust with GPU rendering via a custom GPUI framework — genuinely faster than VS Code with 0.5s startup, 120fps scrolling, and 2.5x lower power draw. Native multiplayer editing baked in from day one. Agentic editing, open-source Zeta model for autocomplete, and multi-model AI panel. Open source under GPL; Windows support arrived in late 2025.
