lambda-toolkit
lambda-toolkit is a Python-based command-line tool for local AWS Lambda development and testing. It enables developers to invoke Lambda functions locally with simulated or real events, import and deploy functions across multiple AWS regions, and manage Lambda environment variables including during local execution. The toolkit features a proxy mode that allows debugging of real Lambda events in real time on a local machine with full breakpoint support. It also provides log tailing capabilities for monitoring Lambda function execution. Compatible with Python 2 and 3 across Linux, Mac, and Windows. Installable via pip. Note: The original author recommends using the Serverless Framework for new projects.
