Visual Workflow Lab
Design, validate and debug automated workflows on a node canvas. Branch with conditions, repeat with safe loops, use variables and math, start from templates, step backwards and import or export JSON.
Launch Workflow Lab →Explore workflows, APIs, machine learning, cybersecurity, finance and physics in hands-on browser experiments with guided steps and free exploration. Free, fast, private, and deterministic.
Choose a simulation environment below to start exploring interactively.

Launch Workflow Lab →Craft HTTP requests against an in-browser mock server, then work through guided scenarios: pagination, authentication and token expiry, retries, rate limits, timeouts and validation errors.
Launch API Playground →Train tiny models right in your browser: a k-NN classifier, a neural network with a live decision boundary, a Naive Bayes spam filter and a word-embedding map.
Launch AI Lab →Safe simulations of hashing, encryption, password strength, authentication storage and phishing awareness. Nothing real is attacked and nothing you type leaves the page.
Launch Cybersecurity Lab →Launch projectiles on other worlds, bend orbits, swing pendulums and watch randomness turn into bell curves, with instant visual feedback as you drag the sliders.
Launch Science Lab →Explore compounding, diversification and risk scenarios, then trade a virtual portfolio in a fictional market. Simulated prices only: never advice, never live data.
Launch Finance Lab →
