"Wow this is insane! I literally spent 5min of copy-pasting React stuff and now I can see the auth page… so, at this point I should consider the frontend auth already set up? if that’s true, then ST is just magical."

Anton Mladenov       [email protected]

“Configuring basic auth features like email verification, session management, refresh tokens, expiration, forgot password feature etc. takes a lot of time and SuperTokes in giving it out of the box. That is what I was looking for :) The simplicity is the key here. I saw plenty of other “safe” solutions, but none of them was simple like yours. I heard great opinions about SuperTokens, that’s why I chose it."

“We are building a system for our startup with highest data privacy and sustainability issues in mind. For that we want to use as much OSS as possible and self host the services. I found SuperTokens and are pretty excited for the software.”

“Two things that give SuperTokens an edge: 1. open-source/ability to deploy the core myself, and its simplicity. 2. Some less-important things that I still think gives supertoken an edge is it is not bundled with a database”

“I have implemented auth dozens of times .. (hydra, keycloak, auth0, okta, cognito). Supertokens is so .. as simple as possible but completely customizable, with ability to own all the data.... The number one complaint they [clients] usually have about auth0, cognito, etc. is that it is difficult or impossible to completely customize the forms and pages, plus it hops out to a different URL for oauth flow.”

Eric Dobbertin       Founder, Sheboygan Works

“What I consider the biggest issue is that Auth0 adds too much complexity on things we need simple, plus, it’s expensive. For an early stage startup I don’t think we should be spending too much cash and time on auth, but this is the reality. And finally, the complexity of customizing the login/registration screens are simply TOO annoying. We have been using both email password + social login”

Wow this is insane! I literally spent 5 min of copy-pasting React stuff and now I can see the auth page...so, at this point I should consider the frontend auth already set up?

If that’s true, then ST is just magical.

Brandon Bayer

Founder @Blitzjs

I' m SO excited to finally ship built-in authentication in @blitz_js !!! Including design, we've been working on this for over 4 months! Thank you to @rishpoddar for being the genius behind our auth!!! Check out his company @supertokensio for framework agnostic session management

Anuj Chabbria

Cofounder @Report Card

Supertokens is our guardian angel. We’re able to secure multiple assets with one library, providing the most seamless and secure experience for our users. Kudos to the Super team!

Fares Siddiqui

Founder @Circadia

We were using AWS Cognito and storing sensitive identity tokens on the frontend. SuperTokens secured our user accounts and patient data, and built an integration for our custom setup

Stephano Paraskeva

Consultant

SuperTokens brings with it, what money can’t buy - trust and transparency. I use SuperTokens in all of my projects because I’m able to control where and how SuperTokens works within my apps, allowing for more granular control over my authentication

Really looking forward to trying this out. Feels like Supertokens may have a 1up on Keycloak though in terms of initial learning
curve and integration effort.Wish you guys the best on this quest!

Love everything about this EXCEPT the choice of Java. Anyways, great work! This
has been something I’ve dreamt of for years (open source Auth0 replacement). I have no doubt you’ll find success.
