Build Your Alexa Skill

Alexa Skills Kit


Build and Host Your Skill in the Cloud

Once you've designed your voice interaction, you're ready to start building your skill. Alexa is based in the cloud so she’s always getting smarter and customers never have to download updates to your skill.

You can build and host most skills for free with AWS Lambda, which is free for the first one million calls per month. You can also apply for AWS promotional credits if you incur AWS charges related to your skill.

Build with the Alexa Skills Kit

Start building with the Alexa Skills Kit, a collection of self-service APIs, tools, documentation, and code samples that makes it fast and easy for anyone to add skills to Alexa.


Refer to our technical documentation for detailed guides on building various types of skills and features.
