We will be sunsetting ServerlessDebugger by the end of March 2023.

However, we are excited to announce that we have been working on a new and open-source solution called MerLoc. MerLoc is a powerful debugging tool that builds on the successes of ServerlessDebugger, while also incorporating new features and capabilities that will help to simplify your serverless development process even further.

Start online debug sessions while the AWS Lambda functions run on AWS Cloud. ServerlessDebugger sets up an easy and secure connection between your AWS Lambda functions and your favorite IDE. Debug your serverless applications natively with their own permissions. Stop mocking resources and simulating the environments! Put breakpoints and pause the execution of the NodeJS and Python functions to see the error, variables, stack trace and more!

Getting started

Don't stop the whole process, just debug one invocation at a time

Debug your serverless app like you debug any code that you host on your computer with native debugging actions, enabling you to see the values of local variables and the entire stack trace.

Debug Lambdas on AWS with their own permissions

Remove the barriers that prevent the ability to debug Lambda functions on IDE.
