No per-user pricing. No feature gating on basics. Credits are pass-through messaging costs — or bring your own gateway and pay nothing per send.
| Channel | Cost / send | Provider |
|---|---|---|
| WhatsApp OTP | ₹0.35 | Meta Cloud API direct |
| SMS OTP | ₹0.40 | 2Factor default route |
| ₹0.10 | ZeptoMail transactional | |
| Voice OTP | ₹0.80 | IVR fallback |
New apps get 100 WhatsApp + 200 email credits free each month. BYO gateway sends: ₹0 — always.
Dedicated Postgres + Redis on our infra, or run the full service on yours — one binary, one env file. The same code that runs nexauth.dev runs on your VM.
OTPless gates Flutter behind an Enterprise contact form. Auth0 charges for authorization as an add-on. Firebase makes you write it yourself. We publish every price, keep auth free, bundle authz, and let you bring your own gateway.
