About Skydex
About Skydex
Skydex is a free flight game in the browser over the real Earth. The aircraft and ships around you are live, heard by a network of volunteer receivers, and you can catch them for your collection. It is made by Esso.dev, a small studio from Kherson, Ukraine.
What it is
Fly a seagull or a drone over 3D scenery of real cities. Spot real ships and aircraft, race drone tracks, fly low over airports and talk to other pilots on the radio. There is nothing to install, and you can start without an account.
The receiver network
The live traffic comes from ADS-B receivers for aircraft and AIS receivers for ships, run by volunteers at home. Every station has its own public page and a place on the leaderboard. Anyone with a receiver can add it in a few minutes.

Is Skydex free?

Is the traffic real?
Yes. Aircraft come from ADS-B and ships from AIS, heard by volunteer receivers and a few public feeds. Private aircraft are shown without their identity.

Photo-realistic cities come from Google Photorealistic 3D Tiles. Elsewhere the world is drawn from OpenStreetMap buildings and elevation data.
