I interview 20-30 people per week and send most of them Hackerrank tests. I'm a big proponent of vetting that people can write code, but 99% of the questions on HR are waaaay too "algorithmic". Had to go through almost all of them to find a few tests that are not about graph algos or dynamic programming – finally found a question that was based on regular expressions and a few other ones that I think are a bit more representative of real world challenges.

I really wish Hackerrank could add more problems or let employers add their own question. Are there any good alternatives to HR?

Hmm, pretty sure you can add your own questions...

I like to add simple coding tasks, multiple choice stuff, and a free form text with 500 chars to explain something..

We (the company I work for) use Codility for some of our roles. I think you can add your own tasks/questions.

Big fan of Codility. They do have a lot of algorithmic questions as well, but they also have easy ones (which we use), and we tested them on our own staff prior to deploying (all then-current staff got perfect or nearly perfect). I would only use medium or above if the question tested something that the job absolutely needed in a candidate.

They also allow candidates to add their own test cases easily, which, for the ones that do, tends to be a very strong signal in their favor (they also tend to do better).

Big NOT fan of algorithmic question that can be summed up in one sentence taking a full page of text description.

In most of these coding test the algorithm is easy, but figuring out the catch in the description is harder than actual implementation (unless you're insanely limited and have to reimplement basics from scratch)

To get a true stress read, I think you would have had to tell your staff that they needed to pass this test to come back to work in the morning.
