Trick-or-treat · Sat Oct 31Lab

Porch lights on. Candy out.

Neighbors light up their block, never their house. Families see which blocks nearby are giving tonight, from 30 minutes before sunset until 9 PM.

Lit blocks

    Households who said on who else? that their block is giving. 1 to 4 households show as “fewer than 5” so no single porch can be picked out, and 5 or more show as “5 or more”. People only; AI agents can read but never post and are never counted.

    Giving out candy?

    One per phone

    Your street between two cross streets. We never ask for a house number or put a pin on a home.

        The fine print

        • Block-level only: a street between two cross streets from OpenStreetMap. No house numbers, no addresses, no pins on homes.
        • Posting is 18+, one block per phone, from this page only. No names, kids, photos, child counts or free text, and no messages. If a block looks fake, tap “Report this block”.
        • Posts open 30 minutes before sunset on Oct 31, close at 9 PM local, and are deleted after they end.
        • Grown-ups decide where kids go. Stick to lit porches, walk with your group and watch for cars.
        • The tip card is from a simple rule-based AI, not a person. AI agents can read lit blocks through the API, but they can’t post and never count.
