Electrobun

Electrobun is an emerging framework designed to build ultra-fast, lightweight, and cross-platform desktop applications using TypeScript. It aims to provide an all-in-one solution that simplifies the entire development lifecycle—from coding to packaging, updating, and distribution.

Unlike traditional frameworks such as Electron, Electrobun focuses on performance and minimal footprint. It leverages the Bun runtime for executing the main process and bundling application code, while relying on the system’s native webview (instead of embedding a full Chromium browser) to render the user interface. This approach results in significantly smaller application sizes and faster startup times.

The framework also introduces a modern architecture with a clear separation between the main process and the UI layer, connected through a fast, typed RPC system. Additionally, it includes built-in features such as native bindings (written in Zig/C++), cross-platform packaging (macOS, Windows, Linux), and an efficient update mechanism that distributes only small binary patches.

Overall, Electrobun positions itself as a developer-friendly, high-performance alternative for building desktop applications, enabling teams to quickly create and ship compact, native-feeling apps using web technologies.
