Free to use
We built this solver because we love doing it, and we want as many people as possible to use and enjoy it.
Therefore, the engine is also the only commercial solver that is free to use in serial mode
with no limitations on problem size.
The engine is very popular (as you can see on NEOS
puts heavy load on our servers, so you might experience a bit of authentication lag on startup with the Community Edition since we have a queueing system in place.
The paid versions interact with dedicated servers so there's no lag there.
