Starlink is LEO, so the only real alternative out there today is Oneweb. Oneweb was originally British, now owned by Eutelsat, French.
Sad news is Oneweb is really not close to Starlink's offering. Their service level is not the same - bandwidth hardly reaches 100Mbps while Starlink is over 300Mbps (and increasing). It is not as user friendly - plug and play - as Starlink is, and their business model is also different. OneWeb is more aimed at B2B, with guaranteed throughput options (something that starlink does not offer), but a pricing that is significantly higher than Starlink. Both the subscription and the terminals. OneWeb is more like the LEO evolution of the traditional GEO VSAT technology, while Starlink represents a technological breakthrough.
Reality is, almost no-one is using OneWeb today. Only reasons being: sovereignty or coverage gaps by Starlink.
A real contender will be Amazon Leo when it is ready. But that is also American, and it will still be almost a year before actual usable service, I am guessing. But looks promising - native integration with AWS is mwah (chef's kiss).
If you don't mind me asking, why did you migrate from Joplin to Notion?
