I had a good experience OTB with Auth0 and pretty straight forward custom OIDC with IdentityServer4(c#) depending your use.. never tried clerk
Clerk works great out of the box! I know the founding team, theyโre doing great work.
Auth0 doesn't scale financially for a side project / non-VC-backed company. Their pricing gets crazy with a moderate number of users.
If your project also touches web3, dynamic.xyz might be a good fit ๐ happy to chat about it if you're open to it!
nextauth? clerk had great dx last time i checked, and auth0 seemed very expensive
Have you checked out https://privy.io ? ๐ It's pretty good, and exactly in this space.
auth0 is expensive AF Supabase uses this open source project internally, might be interesting https://github.com/netlify/gotrue
