Create a geofence. Move through it. Watch OpenFence turn it into evidence.
The same detection engine that powers OpenFence production deployments — turning your location into signed, explainable events you can act on. No signup, right here in your browser.
Best on a phone. We ask for your location only to drop the fence and show movement — nothing is stored to your account.
Drop a circular geofence at your spot and size it with the radius slider. The fence is real — created on the live engine.
Walk with live GPS, or drag your pin across the boundary. Every move sends a real location ping to the server.
OpenFence detects the crossing server-side and a signed enter/exit event lands in your evidence trail — in about a second.
Drop a fence and move
Allow location, drop a fence, then cross its edge. The map is just the surface — the detection happens on OpenFence's real engine.
Locating you…
Below ~50 ft, live GPS can flicker — drag mode is exact. The server clamps the radius to 25–1000 ft.
Or drag your pin across the fence edge — each drag sends a real ping.
Your evidence trail
This is the evidence trail OpenFence just built from your movement — real, signed, explainable events. For a real tenant they fire webhooks into the systems that make the decisions (billing, dispatch, alerts) — exactly the way we're building OpenFence to run WDA Movers.
| Time | Event | Fence | Where |

No events yet. Drop a fence above, then cross its edge — your first signed event will appear here.
Evidence is the product. Geofences are just how it starts.
You just watched movement become signed, explainable events. Point that trail at your own fleet, assets, or customers — and let the systems that make the decisions act on it automatically.
