Carlo

Carlo is a Node.js framework designed to create hybrid desktop applications by rendering Node.js data structures and UIs using a locally installed Google Chrome browser instance. It establishes communication between Node.js and the browser via the Puppeteer project, offering a remote call infrastructure for seamless interoperability. Unlike Electron or NW.js, Carlo does not bundle Chromium, relying instead on the user's existing Chrome installation. This approach can lead to smaller application sizes and leverage an up-to-date browser. The project, currently at version 0.9.46, was last updated in June 2019, and its GitHub repository under `GoogleChromeLabs` shows no recent activity, indicating it is no longer actively maintained. Key differentiators included the ability to bundle the application into a single executable using `pkg`, exposing Node.js capabilities to a web frontend, and leveraging the web stack for dynamic visualization of Node.js app states.
