Comparison
A grounded, numbers-first comparison of Novauth and Sinch for OTP verification — every claim below traces to our published pricing and feature data, updated as our rates change.
Sinch does not offer Telegram OTP or SNA (Silent Auth) — Novauth does (some channels marked "soon").
Every rate is billed per completed verification and published transparently on /pricing — no quote-gated pricing.
$2 free credit, no credit card required. Full docs and test environment included.
