Colab is a desktop IDE built with Electrobun (Bun + native Zig binaries) that combines a code editor (Monaco), integrated web browser, terminal, Git client, and local AI code completions (llama.cpp) into a single workspace. It features a plugin system that allows third-party extensions to contribute commands, custom UI slates, file decorations, context menus, and more. The application uses a main process (Bun) for system operations (file system, Git, terminal, AI) and a renderer process (SolidJS webview) for the UI, communicating via typed RPC. It includes a local database (GoldfishDB) for workspace and settings persistence, cloud sync with encryption, and analytics tracking. The architecture is modular with a focus on extensibility, though some components (store, main index) are monolithic and contain technical debt.
