• Watch out for sprawl

• Run/test AWS Lambda functions locally, or remotely• Auto-deploys, versions & aliases your Lambda functions• Auto-deploys your REST API to AWS API Gateway• Auto-deploys your Lambda events• Support for multiple stages• Environment variable support• Interactive CLI dashboard to easily select and

deploy functions and endpoints• Optimize your Lambda functions for faster response times• Support for API Gateway custom authorizers• 100% Extensible - Extend or modify the Framework

and its operations via Plugins• Powerful classes and methods for easy plugin development• AWS best practices and optimizations built in• A fantastic and welcoming community!
