Unfortunately adsbexchange does not allow you to see the source/destination of flights
Untrue Click on the aircraft, then click on Flight Activity.
To combat this, some countries have started to enforce their countries to use VMS (vessel monitoring system). I say some, but mostly the more resource rich countries - Norway being one of them. VMS also comes with the benefit of much more data capabilities, like fishing vessels sending catch data.
Sensor fusion to detect dark vessels is also a big growing thing. We use around 5 different sensors outside the usual AIS, VMS, LRIT to build vessel tracks. Some are experimental sensors, while others are seeing more mainstream use - like navigation radar sensing.
Maybe a challenge for private entities that want to create these sorts of apps, is data - buying even just AIS data can be expensive at scale. Countries that deal with this often engage in data exchange...some data provider receives data from you, you get some in return for them.

ADSBX used to be volunteer ran until JETNET paid the guy who controlled the domain name $20 million dollars to "sell" it to them and steal everyone else's source code and data. They now do selective filtering to appease their commercial clients. Everyone has moved to https://globe.airplanes.live/ and https://app.airframes.io/flights now. Here is the lawsuit from one former group of contributors: https://www.documentc…
Yeah that really sucked. It was a great volunteer platform and I was sad the guy sold out. It didn't filter anything. Not rich guys' jets, not military etc. The community never really recovered. The airplanes.live one doesn't have as many feeders and the airframes.io is hidden behind a login. I was hoping the community would simply move in unison to a new platform just like what happened when freenode got ruined. But…
What is different from marinetraffic?
Marinetraffic is a good example of enshittification. Started well, now it's heavy and ad-laden, practically useless without a paid account.
This only covers container ships btw. For full coverage of all vessels, try the 'vessel presence' layer in Global Fishing Watch's interactive map, based on a feed from Spire: https://globalfishingwatch.org/map/
Looking good! Thanks for sharing
