Plan a trip.
An itinerary of stays and travel legs. Pick places off a city map, vote yes, maybe or no, drop them onto days, keep notes nobody else sees.

Where we
go.
Trip planning for a small group of friends. One itinerary each, a shared map per city, and a page built for standing on the pavement.
Pick places off a map, vote on them, drop them onto days, and see what your friends are planning where your trips overlap. Nothing leaves the group.

01 / What it does
Four things,
done properly.
Built for one group of friends who travel together and were tired of a shared spreadsheet, a group chat, and six different maps.
Use it on the pavement.
Nearby lists the stay's places by distance from where you stand, your picks first. Add the pharmacy or the good bathroom right there. Your position never leaves the phone.
Plan it together.
Share a stay with friends or a whole crew and see their votes beside yours. A group calendar shows who is where on which day. One-off events live once and everyone RSVPs.
Share outward, carefully.
Publish a scrubbed template of a trip you are proud of. Hand a read-only link to someone without an account. Notes and private plans are never in either.
02 / How it's built
Small on purpose.
RUNS ON THE FREE TIER.
ONE OPERATOR. NO ROADMAP IMPLIED.
SIGN-IN
Passkeys, with Google as the fallback for devices that cannot enrol one. The app never sees an email address.
DATA
The database holds people-data only. Cities and their places are static files. The server filters before anything leaves it.
STACK
Cloudflare Workers and D1. Vanilla JavaScript, no build step, no framework. Leaflet for the maps.
SIZE
Built for about a hundred people. The architecture notes run longer than the code deserves, and that is on purpose too.
03 / Getting in
You already know
who to ask.
Registration is by invitation from someone already inside. There is no waitlist and no form, which is most of the point.
