Textbelt is a very simple SMS API. No user accounts, no cost uncertainty, developer-oriented.

There are two offerings: a free open-source project and a paid API for better delivery guarantees.

Launched OTP API

Shipped a simple API that allows users to generate two-factor authentication/mobile verification codes.

Unlike similar services, there's no account required, the API is dead simple, and the documentation is succinct.

Work begins on a paid Textbelt option

The Textbelt API hosted for free was mostly overrun by spammers and scammers in its 5+ years of life.

The Textbelt.com website begins its transition to a full-service paid. The paid offering uses a different sending mechanism that offers better delivery guarantees and prevents spam.

Users still have the option of self-hosting their free, open-source Textbelt instance.

Textbelt starts as open-source project

First commit of the Textbelt open source project. A free outgoing SMS API that uses email-to-SMS gateways to send SMS for free. Posted to Hacker News shortly thereafter.
