Quick answer: ArcadeLab hosts any single-file HTML interactive content — not just games. Physics simulations, D3 visualizations, math toys, explorables, animated explainers all work the same way. Paste your HTML at arcadelab.ai/publish and get a public URL. The web's best interactive content has always been just HTML, CSS, and JavaScript in a single document. Bret Victor's explorables, Nicky Case's explainers, Distill.pub articles — they were one-document interactive experiences. The Distill aesthetic is the same shape as the ArcadeLab aesthetic. AI assistants are remarkably good at producing these. Ask Claude or ChatGPT for "an interactive single-file HTML page showing how X works" and you get usable output. The missing piece used to be where to host it. ArcadeLab fixes that. What counts as an interactive visualization?…
