Unregistered
Just get it and use it :). No costs, even if you work for a large commercial company. No credit card needed. Do you need to test data, compare some data, …? Just do it :)
You’ll be only limited to 500 tests per one run. There is no limit per day. The only gotcha is if you have more tests, you cannot run them all at once and you’ll have to split them to two or more runs. If you run more than 500 tests in a single run with unregistered editions, only first 500 will have correct results, the remaining tests will have inconclusive result.
You can use CAT only interactively, that means YOU have to start the tests (not a task scheduler, CI/CD process, Jenkins, Azure DevOps, GitHub actions etc.).
CAT runs tests sequentially (in a single thread).
Registered
Everything that is stated about Unregistered edition is valid also for registered edition (free to use even for commercial purposes, interactive use only) - the only difference is the limit for tests run at once is higher - 2500 tests per one run. Again, if you run more tests in a single run, every test above the 2500 tests limit will end up with inconclusive result. You can use CAT only interactively (same as for unregistered edition).
CAT runs tests sequentially (in a single thread).
Licensed
The only paid option. When you have a valid license, you can use CAT as you want. The license is needed for every CAT instance running in paralell. See How is CAT licensed.
CAT runs tests sequentially (in a single thread) by default, but you can configurable how many tests should be executed at once.
