DropZone Local Finder — Hyper-Local Lost-and-Found Board
Hyper-local lost and found board: post or find dropped items near you, scan your transit route for things found along the path. Anonymous, no login.
Post or find dropped items in your neighborhood. Scan your commute or walking route for things found along the path.
It runs entirely in your browser. No account, no app store, no tracking.
DropZone uses HTML5 Geolocation, OpenStreetMap, OSRM routing, and the Overpass API. All item posts and recovery claims live in your browser's local storage. Your board is built up from neighbors using the same URL.
How DropZone works
DropZone runs on the idea that location does most of the work:
- Your browser centers the board on your neighborhood using HTML5 Geolocation — no account, no typed address.
- The tool reads the place around you from OpenStreetMap via the Overpass API: nearby parks, bus stops, transit centers and landmarks, generating clean spatial tags for the board.
- When you post a found item, you drop it at a location and pick the tags that match where it happened — the park gate, bus stop, plaza outside the station. It goes on the board, marked observational and unverified.
- When you lose something, you browse the local board or scan the route you travel. In route mode you enter a start and destination, and DropZone uses OSRM and Overpass to scan the walking path for posted items near the line you walk.
- If you match with an item, you coordinate informally — no personal data, no login — so you can agree to meet in a public place.
Distance is the enemy of recovery: a found wallet a mile away goes to an office; a found wallet at the corner stop has a real chance of getting home.
The locations behind the tags
DropZone reads the map through the Overpass API, the free public database engine for querying OpenStreetMap data.
Neighborhood parks — leisure=park
Parks are a lost-and-found hotspot: benches, playgrounds, and the paths people cut across on the way home.
Bus stops — highway=bus_stop
A bus stop is where passengers can board or alight from a bus, marked by a shelter, pole, or road markings — exactly where commuters stand each day.
Local landmarks — tourism=*
Landmarks include attractions, viewpoints, and museums — recognizable places people use as meeting points.
Transit centers — public_transport=*
Places where passengers wait (platform) and larger interchange points (station) — high-traffic areas where items are dropped constantly.
Scanning your commute or walking route
Most losses happen along the way, not at a single named place — and route mode is built for that.
You enter a start and destination, and the tool converts them to map points. It calculates the path between them with OSRM, the Open Source Routing Machine. Then Overpass scans the corridor around the route — the walk to the station, the commute down the main road — and surfaces posted items near the line you actually travel.
The honest part
The route is the likeliest path between two points, and the board only shows what people have posted. It is a strong lead generator, not a guarantee the item is there.
How posting and recovery work
Everything is deliberately simple and local:
- Zero registration. No account, no email, no profile — you use the board as a guest of your own browser.
- All client-side storage. Posts and claims are stored in your browser's local storage. Nothing is uploaded, nothing is tracked.
- Every post is marked observational and unverified. As an anonymous dropped-key finder, nobody is vetted and no claim is confirmed.
- Recovery happens offline and in person. DropZone helps a finder and a loser see each other's posts; the exchange is a human act between two people meeting in public.

Frequently Asked Questions
Is DropZone a guarantee of recovery?
No, and it is important nobody treats it that way. DropZone is a coordination board: it helps a finder and a loser discover each other's posts. It does not retrieve items, store them securely, or confirm that any claim is true. Recovery happens offline, in person, between the two people on the board.
Do I need an account, and is my board public?
No account and no personal data. The tool runs in your browser and posts live in local storage; nothing is sent to a public server. The tradeoff is that the board only works among people who actually use it.
Where does the map data come from?
From the free public OpenStreetMap ecosystem. Map data is volunteer-contributed under the Open Data Commons Open Database License (ODbL). Attribution to OpenStreetMap is required. Geocoding uses Nominatim, place queries use the Overpass API, and route scanning uses OSRM.
Are posted items verified?
No. Every post is marked observational and unverified, and anyone can post or claim — DropZone cannot check either. Treat every claim like a lead you confirm in person, and meet somewhere public.
Does the tool work everywhere?
It works anywhere OpenStreetMap has data, which is most of the planet, but only as well as the local map and crowd. Well-mapped cities give rich anchors; sparse areas return fewer, and the board is thin where few people use it.
Why does recovery happen in person?
On an anonymous, no-login board there is no verified identity and no way to mail an item to its owner. Overlapping location is the only real proof, and meeting lets both sides confirm the item — which is exactly why meeting in public matters.
