Let's talk about Deno Desktop

Short summary

An overview of Deno Desktop, shipped in Deno 2.9, which lets developers build desktop apps by simply serving HTML through Deno.serve with no extra build step. It defaults to the OS webview (~19 MB compressed) but supports bundled Chromium (~150 MB) for pixel-perfect rendering. In-process function binding replaces IPC message channels, reducing the friction of backend-to-frontend communication that plagues Electron and Tauri.

• •Deno Desktop uses Deno.serve to open a native window — no build step or second project structure
• •Defaults to OS webview (19 MB) vs Chromium (150 MB), with raw mode for custom rendering
• •In-process win.bind() replaces IPC channels, eliminating serialization overhead
