How many devices does one cursor account support?
I want to know limit about $20 plan.
Just to add on to the above question . Is the limitation is on number of devices per account or concurrent usage of service?. Let say, I have couple of laptops and one desktop on which cursor IDE is installed. I may not be using cursor (service) on all the devices at same time though IDE could be left open after last usage
Try and find out, I’ve seen people being blocked this way though, so there is a threshold where it will detect it. 
Concurrent use that is, bet two machines that aren’t used the same time won’t give any issues.
Dont think the 20 plan would be sufficient though, you’ll burn through the fast requests in a week, if you share it, bet it will be over in a day or two.
You should be able to use 3 machines with the same account before you get blocked, but we do detect and monitor concurrent usage. If you’re jumping between two machines, you’ll probably be fine, but you won’t be able to share a Pro account with 2 other people simultaneously.
