General

Q: What is the Amazon Chime SDK?

The Amazon Chime SDK is a JavaScript software development kit that uses resources in your AWS account to make it easy to add collaborative audio calling, video calling, and screen share features to your web applications. Customers can now use the same infrastructure services that power Amazon Chime online meetings in their own applications.

Q: How can I use the Amazon Chime SDK in my application?

Your server application will use the AWS SDK to manage the lifecycle of meeting session resources in your AWS account and control how they are accessed. The Amazon Chime SDK for JavaScript is embedded into your web application to build a custom communication experience. The Amazon Chime SDK includes methods to connect the client applications to cloud meeting resources, manage microphone and camera selection, and control meeting features.

Q: What browsers does the Amazon Chime SDK support?

The following browsers are supported for applications created using the Amazon Chime SDK:

• Mozilla Firefox (version 60 and newer), for macOS and Windows
• Google Chrome (version 78 and newer), for macOS and Windows
• Chromium-based Edge (version 79 and newer), for Windows
• Chromium-based Electron (Electron 7 and newer, with Chromium version 78 and newer)

Q: Do I need to use the Amazon Chime application to use the Amazon Chime SDK?

No. The Amazon Chime SDK works independently of any Amazon Chime administrator accounts, and it does not affect meetings hosted on Amazon Chime. Instead, the Amazon Chime SDK provides builder tools for developers to use to build their own meeting applications.

Q: Do I need an AWS account to use the Amazon Chime SDK?

Yes. You must have an AWS account to create meeting resources that will be used by your application to connect audio, video, and screen sharing.

Q: Are there sample Amazon Chime SDK applications that I can use as a starting point?

Yes. The Amazon Chime SDK is available in a github repository https://github.com/aws/amazon-chime-sdk-js along with several examples and a demo application. See the README for information on running the demo application.

Q: What programming languages does Amazon Chime SDK support?

The Amazon Chime SDK for JavaScript is suitable for implementing in a web application and can be used from JavaScript or TypeScript applications.

Q: In which regions can I use the Amazon Chime SDK?

The Amazon Chime SDK allows you to create media sessions in US East (N. Virginia) and US West (Oregon).

Q: What are scaling limitations?

The Amazon Chime SDK allows you to create meeting resources in your AWS account that are capable of hosting up to 100 audio attendees with up to 16 shared video streams.

Q: What audio, video and screen sharing specifications are supported by the Amazon Chime SDK?

The Amazon Chime SDK samples audio at a rate of 16 kHz and encoded using the Opus codec. The VP8 codec is used both for video and screen sharing. Video is supported at resolutions up to 1280x720 at 15 frames per second. Screen sharing is supported at 3 frames per second.

Billing & Pricing

Q: How is the Amazon Chime SDK priced?

There is no direct charge to create a media resource in your AWS account. You are charged $0.0017 for each minute that each attendee (i.e. each client implementing the Amazon Chime SDK) is joined to your meeting session with audio, video, or screen share.
