Clerk

Extremely easy to integrate into your service. Excellent documentation.

good

Clerk is a great auth service for building web apps. It makes it easy to add auth and user management, my experience with React/NextJS. Looking forward to seeing what the team adds next

An excellent and much needed solution for User Auth in the JS framework space. If anything - this is belongs in your stack if you're someone like me who likes to ship fast and doesn't want to get bogged down in configuring User Authentication, Webhooks, API keys and tokens for all the different providers you might require in your Auth flow.

Stop googling for a solution and just use this. This is likely exactly what you need. Clerk helps you avoid the hassle of having to deal with authentication both on the BE and the FE. It is not worth opting for another free/open-source solution as the free tier on Clerk is quite generous and will help you get started.

The best alternative from auth0 to react ecosystem

Clerk has been great for us - we've barely had to think about the ins and outs of auth and the fact that it's geared toward B2B use cases is perfect. Very easy to manage users, organizations, limits, different auth setups etc. Some hiccups since we're building a native-app vs. web but all in great experience. 💯

These guys are the best!

10/10 DX 😁 But... more free users (or a consumer product oriented plan?) and I wouldn't use anything else.
