SystemDesignBoard

About

A browser based whiteboard designed for system interviews, focused on keyboard efficiency. It includes nodes for services, databases, and cloud providers like AWS, GCP, and Azure. Use animated connectors for synchronous, asynchronous, and streaming links. Key trade offs are highlighted with badges for concepts like the CAP theorem and scaling. Define diagrams with code syntax, such as typing [A] -> [B x3] for automatic layout. Export your work as a PNG or an animated GIF. The tool also features an interview timer and a scratchpad for calculations. No account is required, there are no usage limits, and it is completely free while in beta.
