Deployment flexibility is one of the biggest reasons why people prefer @TesseralHQ to Auth0... that, and the fact that we're built specifically for business software, makes B2B SaaS user management / auth dead simple.

Open source. Multiple deployment options. All the features B2B software needs, out of the box. 📦🚀 We're often asked how we compare to auth providers like Auth0. The short version? We're not general purpose, we're built for B2B. The long version? 👉 tesseral.com/compare/tesser…

Auth products have a ton of feature bloat with consumer junk and customizations no one building B2B products will ever need. It's really annoying. That's why we built @TesseralHQ, to get B2B auth right. It's a great product. You should check it out: tesseral.com

Consumer auth doesn't cut it for B2B SaaS. Business software needs SAML, SCIM, RBAC, and audit logs, not Log In with Facebook. Our CTO @ucarion joined @github's @itsthatladydev to demo our open source auth platform, specifically for B2B. 📺Watch here: youtube.com/watch?v=nPnb57…

There are lots of ups and downs in building a company, but I'm lucky to ride them out with the @TesseralHQ team. Even if the office still faintly smells like dishwasher salmon...
