Authentication & Communication. One Platform.
Stop gluing Auth0 to SendGrid. Zyphr unifies user authentication and transactional messaging in one developer platform — with zero glue code.
The multi-vendor problem
Most teams cobble together 5+ services just to handle auth and messaging. Each vendor has its own dashboard, billing, API patterns, and failure modes. When a user signs up, you write glue code to trigger a welcome email. When they reset a password, more glue code. It compounds.
The typical stack
Auth0 — Authentication
SendGrid — Email
OneSignal — Push
Svix — Webhooks
Custom code — Glue logic
5 dashboards. 5 billing cycles. Endless glue code.
The Zyphr way
One API for auth + messaging + webhooks
Auth events automatically trigger messages
One dashboard, one bill, one SDK
Full observability across auth and delivery
Swap providers without changing your code
Auth-triggered communication
When a user registers, Zyphr sends the verification email automatically. Password reset? Same thing. Every auth event can trigger email, push, or webhooks — without you writing a single line of integration code.
One SDK, zero glue code
See how a single API call handles user registration, email verification, and webhook delivery.
register-user.ts
// User signs up → auth + welcome email + webhook in one call
const { user } = await zyphr.auth.register({
email: 'jane@example.com',
password: 's3cur3P@ss',
});
// That's it. Zyphr automatically:
// 1. Creates the user session
// 2. Sends the verification email
// 3. Fires the user.created webhook
// No glue code. No extra API calls.Everything in one platform
Six capabilities. One API. No integration tax.

Frequently asked questions
How is Zyphr different from using Auth0 + SendGrid?
With Auth0 + SendGrid, you need to write glue code to connect authentication events to email delivery. Zyphr handles this natively — when a user registers, resets a password, or verifies their email, the corresponding message is sent automatically through your configured provider.
Can I use Zyphr for just auth or just email?
Yes. Each capability works independently. You can use Zyphr for auth only, email only, or any combination. The real power comes from using them together, but there is no lock-in to the full platform.
What email providers does Zyphr support?
Zyphr currently supports AWS SES with built-in deliverability optimization. Additional providers (SendGrid, Postmark, Mailgun) are on the roadmap with automatic failover between them.
Is there a migration path from Auth0 or SendGrid?
Yes. Zyphr provides API-compatible endpoints and migration guides. Most teams complete the migration in under a day. See our comparison pages for detailed migration steps.
How does pricing compare to multiple vendors?
Zyphr starts free with 1,000 emails and 1,000 auth users per month. A typical team using Auth0 + SendGrid + a webhook service would pay $150-400/month — Zyphr Pro covers the same usage for $79/month.
