Mojo IPC (Inter-Process Communication) is a messaging system used primarily within Chromium-based browsers, such as Google Chrome and Microsoft Edge. It enables secure and efficient communication between different browser components, like the renderer, GPU, and browser processes. By isolating processes and controlling message flows, Mojo IPC helps improve browser stability, performance, and security. It replaces older IPC mechanisms, offering better modularity and flexibility for developers. Mojo’s design also supports sandboxing, reducing the risk of vulnerabilities spreading between processes. Its architecture is key to the secure operation of modern web browsers.
