Everything your backend needs

Production-grade APIs without the infrastructure overhead.

✉️

Email OTP Service

Security-first

6-digit codes with cryptographic hashing, brute-force protection, and automatic TTL cleanup. Delivered via your own SMTP.

🔗

Magic Link Auth

Passwordless

Passwordless sign-in flows. Signed single-use URLs with configurable expiry and optional redirect. 256-bit entropy.

📧

Email Confirmation

Auditable

Account activation links with 72-hour TTL. Soft-delete audit trail so you know exactly when each email was confirmed.

Spin up isolated MongoDB environments for E2E tests. Auto-provisioned by background workers, auto-destroyed after 24h.
