SST (Serverless Stack) is a framework that makes it easy to build serverless apps. It features: -- - A Live Lambda Development environment - Zero-config support for ES and TypeScript - Higher-level constructs designed for serverless

Hi Product Hunt, We are Jay and Frank and we are building SST. We've been serverless community members and builders since 2016. We had originally created Serverless Stack (https://serverless-stack.com) as a guide for building serverless apps. Over the years we noticed that our readers had a really hard time testing and debugging their Lambda functions. And there aren't any good solutions out there. For some background, there are two main approaches to local Lambda development. 1) Locally mock all the services that your Lambda function uses. So if your Lambda functions are invoked by an API endpoint, you'll run a local server mocking the API. However, if your Lambda functions are invoked asynchronously or need authentication, it becomes really hard to set this up. 2) You'll need to redeploy your changes to test them. You'll make a change to a Lambda function, deploy that specific function, trigger your workflow, and wait for CloudWatch logs to show your debug messages. This can take a couple of minutes and can be really painful. So we created SST. The `sst start` command deploys your serverless app and deploys a small _debug_ stack (a WebSocket API and DynamoDB table) along with it. It'll then stream any Lambda invocations to your local client, run them locally, and send back the results. This means that you can make changes to your Lambda functions and test them live! It supports all the Lambda function triggers, without having to mock anything. Debug logs are printed right away to your local console. And there are no third-party services involved. You can read more about SST over on our docs (https://docs.serverless-stack.com) and check out some examples (https://serverless-stack.com/exa...). Thank you for reading about our project. We'll appreciate it if you took it for a spin and gave us some feedback.

I love what the team has done here! The live-development workflow is a game changer for me! Moving away from Serverless Framework to SST currently! Awesome support on Slack from the team as well! 👏

@pal Thank you for the kind words Pal! And really appreciate your support!

I’ve recently began using the tutorial written by your team to learn your stack, and I love how easy it is to get up and running. I have to start doing some backend coding at my job, and our backend lead used serverless-stack to set everything up and he has nothing but amazing things to say about it. So far it’s been a great experience and the learning curve isn’t bad at all. Great work! Look forward to using it on future projects as well!

@devindford Thanks Devin! I'm glad that it's been working well for you and your team!

SST was a game changer in IAC. I mean I have been through pulumi and AWS CDK and I love the idea of typesafe IAC in a real programming language. But the deployment speed of CDK and others is quite slow. So I was able to 10 fold my iteration speed with SST. I also liket the console for logging!

Actual AI's backend is all hosted with SST - it is just incredible

I generally use AWS for all of my infrastructure needs but I hate messing with CloudFormation. CDK was nice but was also a bit cumbersome to get right. SST is CDK but on steroids. They make it super easy to create the primitives you need to GSD, without worrying that much about the specifics. And if you ever need to get in the weeds, you can create your own CDK constructs to do so.
