What is Cascade
A service that delivers codes and links quickly and affordably
Cascade helps websites, apps, and companies send verification codes and short links to users. The goal is simple: get the message delivered as fast as possible and as cheaply as possible.
What it is for
Sign-up, login, phone checks, payments, orders — anywhere people need a code or a link on their phone.
What it solves
Expensive SMS, slow delivery, and painful setup. Instead you get a simple service with clear pricing and a fast start.
How it feels
You send a request — the user gets a message. No extra steps and no complicated configuration.
Cascade delivery
Why messages stay cheap and still arrive
Cascade does not rely on a single delivery method. If one option is less effective or less affordable, the system automatically uses another. That is why messages stay cheap and still reach users quickly.
Start with a better channel
The message goes through the most convenient available option — for example, WhatsApp.
If needed — another path
If that option is not a good fit, Cascade tries the next one on its own.
The user gets the code
People still receive the message, and you pay much less than for classic SMS.
In plain words: the service picks a better delivery path so messages are both cheaper and more reliable.
How the service works
From user sign-up to a ready code
It all happens in seconds — no manual work and no waiting around for an SMS that may never arrive.
