Heads up: uploaded files get baked into this URL and it's getting long. Prefer GIF links from the picker, or run the customizer as an OBS custom dock so settings sync locally instead of through the URL.

The preview runs in demo mode: it never sends chat messages or fires your Streamer.bot actions. Settings save to this browser instantly; the copied URL carries your full config baked in, so it works in OBS on any machine.
