ADS-B Exchange – World's largest co-op of unfiltered flight data
Home – Serving the Flight Tracking Enthusiast
Welcome to, a co-op of ADS-B/Mode S/MLAT feeders from around the world, and the world’s largest source of unfiltered flight data. Thanks to our worldwide community of participants, if the data is broadcast over the air, you can find it here. This opens up a whole new world of interesting traffic for hobbyists, without materially affecting security for anyone.

In fact, ADSBexchange is proud to collaborate with C4ADS to support its mission to produce data-driven reporting to understand, prevent, and mitigate global c4logoblackconflict. Over the coming months, this partnership will yield more receivers in interesting and unusual global locations, ADSBexchange will have wider coverage and C4ADS will have more data to enhance their mission.

Although you can do it here, this is not the go-to site to track your grandmother’s flight from Cincinnati to Chicago so you can pick her up from the airport. For that, I recommend

ADS-B Exchange differs from typical flight tracking sites in two primary ways. First, all data sent in from the community is, in turn, made available back to the community through various archives and APIs. ( Best of all, for non-commercial use, all of this data is freely accessible to anyone!

Trick Yourself Into Writing Well by Telling Yourself to Write Badly
