Use case

What to add after Better Auth

AscendKit is built on Better Auth, so it is a companion, not a replacement. Better Auth gives you free, self-hosted login with user data in your own database. AscendKit adds the layer you need next: transactional and verification email at scale, lifecycle journeys, NPS and CSAT surveys, webhooks, and a hosted dashboard — while keeping the own-your-data model Better Auth users chose.

How it works

  1. 1. Keep your Better Auth foundation
    AscendKit wraps Better Auth, so your existing login, sessions, and own-your-data setup stay in place.
  2. 2. Add the lifecycle layer
    Turn on transactional and verification email, lifecycle journeys, and surveys from one project keyed to the same user record.
  3. 3. Get a dashboard
    Manage auth settings, email templates, journeys, and survey analytics from the hosted portal instead of building admin UI yourself.

FAQ

Is AscendKit a replacement for Better Auth?

No. AscendKit is built on Better Auth and complements it. You keep Better Auth for login and add AscendKit for email, journeys, surveys, and a dashboard.

Do I lose the own-your-data model?

No. AscendKit follows the same model — user records stay in your own database while AscendKit acts as the control plane.

Start with one API key

Auth, email, surveys, and journeys share one user record, so you ship this without stitching vendors together.
