Flow Visualizer is a free, open-source, browser-based tool for testing layout and staffing decisions. You upload a 2D floor plan and Muse Spark reads it, placing the entrance, queues, service points, walls and doors as a schema-checked model. You describe arrival rates and service times in plain words, and a discrete-event simulator runs 30 replications, checking results against Erlang-C and Little’s Law. The plan comes alive as an animated replay, with a measured share of customers who leave because the line is too long. Muse Spark then reviews the results and proposes changes, and every suggestion is re-tested in the simulator before the user sees it. The AI never decides the numbers. It runs fully in the browser, and your API key stays on your device.
