Native GPU windows, WebGPU-first libraries, and real apps running on WGPU — now built into Electrobun. Here’s what shipped and how to use it.

Two years in the making: Electrobun hits v1 with first-class macOS, Windows, and Ubuntu builds, tiny differential updates, and a framework that finally feels built for modern desktop apps.

zig-bsdiff is our SIMD-accelerated, zstd-powered binary diff/patch tool that powers Electrobun’s differential updater. We spun it into its own open source project so you can use it for fast, small patches in your own pipelines.

co(lab) is a hybrid code editor + web browser with both WebKit and Chromium tabs, built-in Git + GitHub flows, full PTY terminals, and local-first AI. The developer preview is free to download and open source—here’s what’s inside and what’s coming next.

This post dives deep into the architecture of OOPIFs and the evolution of Electrobun’s implementation of the <electrobun-webview> “super iframe.”

How Electrobun grew from the need for a tiny, fast desktop app framework with efficient differential updates and a TypeScript-first development experience.
