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/
https://www.marinetraffic.com has most AIS transponders, I use it to track friends on commercial and private vessels.
https://aprs.fi also shows AIS (as well as ham radio operators which is its primary function)
Thanks for the recommendation, looks interesting. I've used Vessel Finder due to something being a nuisance with Marine Traffic.
https://aisvesseltracker.com/ is a good one too. Shows a LOT more, including cruise ships and pleasure craft.
Doesn't track all container ships. I'm looking out my office window at Eliot Bay (Seattle), I see two container ships not on the map.
It's also a bit limited. The gold standard is still kpler.
Years ago I used to subscribe to a service that did this for oil tankers and tried to estimate oil to each route, they wrote a weekly summary. Eventually they decided they only wanted enterprise clients and not people like me who, working in devops, had no need for this service at all and only paid the $20 a month out of some weird fascination
Meta: I like the use of an actual globe when zoomed out. Wish more things would do this.

I bet many of you can guess what scene from what show that points to.
