Free travel tools
Deterministic calculators — the same math the rules are written in. No accounts, no ads blocking results, nothing to expire.
Rules that are expressed in numbers deserve tools that answer in numbers. Each tool below encodes the exact regulatory thresholds — 100 watt-hours, 3.4 fluid ounces, 24% and 70% ABV, one quart-size bag — so the answer you get is the same answer the checkpoint officer applies. Everything runs instantly in your browser: no sign-up, no email wall, no "watch an ad to see your result", and nothing that can expire. Your inputs never leave your device.
