About OTP Bolt

Last updated: 30 October 2026

OTPs at the speed of lightning. OTP Bolt started from a simple frustration: testing a signup flow shouldn't require a drawer full of SIM cards, and trying a new app shouldn't cost you your personal number's privacy.

We built a fast, modern alternative to the cluttered SMS-receive sites of the past — a real-time inbox, honest per-code pricing with automatic refunds, a clean REST API for developers, and dedicated numbers with browser calling for when one code isn't enough.

What we believe

• Speed matters. Codes should be on your screen the moment the carrier delivers them.
• Pay for results. If the SMS never arrives, you shouldn't pay for it.
• Developers first. Everything you can do in the dashboard, you can do over the API.
• Responsible use. We build for testing and privacy, and we actively fight fraud.
