This is an Open Core product. The open source part of it seems to be quite limited (see https://supertokens.com/pricing) and therefore I have a hard time believing this version can be "an alternative to [...]".
Actually, the main motto of the frontpage is "Open Source User Authentication", which I also think is a bit of a mischaracterization of the software, since key features I'd look for on an authentication software are not open source.
I love that this is a Java-based project and the goals and ideas behind it; but I think the so prominent use of the terms "open source" is misleading and I recommend demoting them or using alternative terms to reflect a more precise reality.
