# GrizzlySMS alternative

GrizzlySMS is known for a catalog of thousands of services in many languages. The question is not catalog size, it is whether the number you buy for your app and country actually receives the code.

## Is SMS Nitro a good GrizzlySMS alternative?

Yes if you value seeing the recent success rate of each country before paying, a balance that is charged only on delivered SMS, and an API compatible with the tools you already use. GrizzlySMS has a larger catalog; SMS Nitro focuses on the apps and countries with verified prices and delivery.

## What GrizzlySMS is

A marketplace with activations, rentals, a site in nine languages (including Portuguese and Spanish) and a blog aimed at search traffic. It serves a broad international audience and lists more than 2,300 services.

## What SMS Nitro does differently

- Private numbers only, never shared inboxes.
- Price frozen at purchase, charged only when the SMS arrives; the number is reserved for 20 minutes.
- Live price and recent success rate per app and country before you confirm.
- Card and crypto top-ups from $5, balance that never expires, no subscription.
- REST API plus an SMS-Activate-compatible endpoint, so existing tools migrate by changing the key.
- Catalog written in each language from scratch, with a legal entity, refund policy and support behind it.

## Moving from GrizzlySMS to SMS Nitro

Create an account, top up from $5 and compare the prices of the apps you use most. If you used GrizzlySMS through its API, the SMS-Activate-compatible endpoint lets most scripts run unchanged after you swap the base URL and the key. Numbers that receive no SMS are never charged, so testing a new provider costs nothing when it fails.

## FAQ

**Does SMS Nitro have as many services?** No. SMS Nitro lists the 700+ apps with verified prices and delivery through its carrier partners, rather than every service name ever seen.
