Use the Azure DevOps Test Plans with any technology you want as you're just using the manual test features, you could even use it to manage the test process of any product.
There are elements in the Test Hub that integrate with Azure. Spinning up a test environment after a build and automatically logging the results of an automated test is an apt example. It can also be used with any other cloud or on-premise environment as long as you use a tested technology Azure DevOps is familiar with.
