Use cases

Practical guides for the things SaaS teams build first — auth, email, surveys, and lifecycle journeys — on one platform with a single user record.

Add auth and transactional email to Next.js
Add authentication and transactional email to a Next.js app with one platform and one API key — no separate Clerk plus Resend setup.
Add NPS surveys to your SaaS
Add NPS, CSAT, and custom surveys to your SaaS with built-in distribution and analytics — tied to the same user record as auth and email.
Lifecycle email without Loops
Run onboarding and lifecycle email journeys triggered by your own product events — without bolting Loops onto your auth provider.
Add authentication to FastAPI
Add hosted authentication to a FastAPI backend with the AscendKit Python SDK — credentials, magic link, and OAuth without building auth yourself.
Build user onboarding journeys
Build a multi-step onboarding journey driven by product events and timers, with email and surveys on the same user record.
