Logto has helped us to include authentication fast and easily. If you are looking for an authentication layer this is the solution.

We have been using Logto as THE authentication system and it has truly been a game changer. The integration was seamless and it significantly improved user experience.

Amazing product. True Auth0 killer with nothing shy of it. Open source and free on premise forever with a stunning admin UI. What's not to like? Already central to the stack of my next product launch.

Logto Cloud is an incredible solution for startups and scaleups who need authentication. It was easy to get up and running and since it supports OAuth, integration into our other systems was seamless. Highly recommended!

The UI is great, the docs is good too, the design is modern enough, a great product with a great future. And the team is super helpful and present.

The team have helped me so much with my auth system. With the core being Logto, I only need to implement other verifications around it. Logto IS AMAZING and I see the commitment of the team!

If you quickly need to add auth to your app be sure to check out @logto_io. It's easy to use and modern, has a great team behind it and it's even open source! #logto

For those who look for an auth system, I would recommend give Logto a try. I switched to its beta version after using a kind of traditional auth system for about ten years.

But before adding more features I decided to migrate the current user auth system, which is powered by @nextauthjs , to a new one that has better support for SSO integration with ease. Checked several solutions, @logto_io looks quite promising! Hopefully I can get this done soon.

I am migration the authentication system from Firebase to Logto. The docker environment helps a lot and it's really a out-of-the-box solution for my needs. I am going to experiment how can I integrate its RBAC module into my Symfony application but I don't expect any issues because everything was so smooth so far.

if you're building a saas and your authn is not built with something like @logto_io, then you're definitely wasting precious developer time on authn.
Your time should be spent on business logic not auth.
Try out logto, it takes less than 1hr to setup & understand.
