Pricing is calculated based on the number of published messages, the number of subscribed messages, and payload data:

- publish requests are $0.30 per 1 million and $0.017 per GB of payload data

- subscription messages are $0.01 per 1 million and $0.001 per GB of payload data

Data transfer out of Amazon SNS is also charged. Pricing varies depending on the volume of data. For example, the first 1 GB per month is free, while the next 9.999 TB costs $0.09 per GB.

Note that we have used US East (Ohio) as a reference point, but the pricing values differ across regions.

Pricing is divided into two categories: Sendbird Chat and Sendbird Calls.

Sendbird Chat is $399/month

“The global AWS community is present on a multitude of platforms, ranging from Stack Overflow and GitHub to Medium, Discourse, and even Reddit. Of course, the SNS community is significantly smaller in size, but objectively speaking, still pretty big. To be more specific, there seem to be a lot of people interested in the product. If you look at the AWS SNS forum, you can see that some of the threads have even 20.000 or 30.000 views. Unfortunately, there seem to be a lot of questions without an answer. You can find some cool stuff on GitHub, such as an extended client library for Java that enables you to publish messages bigger than 256 KB.“

Sendbird has tiny but growing community presence on a few channels such as StackOverflow (less active) and their website (more active), with a fair number of users and engagement (but a small number of tutorials). Stackoverflow has some answered questions.
