 Serverless is amazing and solves many issues with traditional systems. However, writing code for Lambda functions can be challenging. The cycle of writing, deploying, running, fixing, and redeploying is time-consuming and tedious. You could use tools to run Lambda locally or use unit/integration tests; those approaches often don't replicate the actual environment closely enough.
 
+Lambda Live Debugger provides several features that aren't supported by SST or Serverless Framework v4::
+
+- **Observability mode** – Enables debugging without impacting the system, so it can even be used in production.
+- **Quick toggle** – Debug mode can be turned off and back on almost instantly without requiring a redeploy like other solutions.
+- **Selective debugging** – You can debug only one or a few functions at a time, which is crucial for large and complex systems. Running many Lambdas simultaneously on a single machine can be confusing and can slow down your computer.

 ## How It Works
 
 Lambda Live Debugger connects to your deployed Lambda, routes requests to your computer, and sends responses back to the deployed Lambda. This allows you to debug locally, but the system behaves as if the code is running in the cloud with the same permissions. In case of code changes, you do not have to redeploy. The code is reloaded automatically without deploying or even restarting the debugger.
