The Clerk branding is a non issue really. I mean, you just use the components and remove it with CSS lol, easy peasy. Although, I left it on one of my apps because I actually thought it made it look more secure but that's just me. My users aren't in the "know" so ymmv.
Splitting hairs, but the authkit.app domain basically is an ad no?
Yeah, I agree on the MFA and Passkeys. Impersonation is a toss up for me, I understand where they're coming from but also would be nice if it was in the free tier.
Looking at the authkit docs, unless I'm using Next or Remix... I need to store the refresh token, manage refreshing the access token, verify the access token, manage revoking the session and deleting the cookies. Clerk does all that for me so that's a win in my book (I understand you folks are working on more SDKs, so that'll be cool).
I don't doubt that Authkit is good, and I like seeing the competition. Clerk has been good to me for quite some time now. I've had to go into their Discord a few times for help and they were awesome, so that's kept me around even through the problems I've had. I've never felt like I was getting inferior support for being a free customer. I guess I'm more ride or die for Clerk than I thought lol.
But hey, to your credit you've convinced me to try out authkit on my next project so that's a win for you there. I'm always open to seeing what's out there.
