Electrobun

Electrobun is a framework designed for building ultra-fast, tiny, and cross-platform desktop applications using TypeScript. Leveraging the Bun runtime for the main process and native system WebViews (WebKit on macOS, WebView2 on Windows, WebKitGTK on Linux) for rendering, it offers a compelling alternative to Electron by drastically reducing bundle sizes (often around 12-64MB) and memory footprint, as it avoids bundling a full Chromium instance. The framework provides a complete TypeScript-first API for both main and renderer processes, including type-safe RPC for inter-process communication, and eliminates the need for languages like Rust (as seen in Tauri). It boasts a differential update mechanism (bsdiff) allowing for extremely small application updates, sometimes as low as 4KB. Current stable versions are `v1.x`, with active beta development continuing in the `v1.17.x-beta` series, indicating a frequent release cadence for enhancements and fixes.
