terraform
Terraform enables you to safely and predictably create, change, and improve infrastructure. It is a source-available tool that codifies APIs into declarative configuration files that can be shared amongst team members, treated as code, edited, reviewed, and versioned.

ℹ️ tl;dr: If you want to skip ahead and just compare the structure and configuration for each project, including the code for the actual Lambda functions, you can find them all here.
Terraform is a widely used Infrastructure-as-Code tool with open-source modules available for virtually any API, including AWS. In contrast to all previously discussed tools, Terraform does not produce and deploy CloudFormation. Instead, it talks directly to the AWS API and keeps track of its state on its own.
Serverless Framework is an open-source tool built specifically to simplify building serverless apps. While it does support other clouds, such as Azure and Google Cloud, AWS is definitely where the focus is. It's found a carefully balanced way of abstracting away “just enough” of the parts you may not care much about while allowing you the flexibility of CloudFormation when you need it. For a long time, Serverless Framework was the clear choice for many development teams.
Pulumi is another universal Infrastructure-as-Code tool, but instead of using a DSL, you can use Python, JavaScript, YAML, or other familiar programming- and markup languages. Like Terraform, Pulumi manages its own state instead of using CloudFormation.
SST is a batteries-included framework built on top of AWS CDK with a strong focus on developer experience. It includes high-level constructs for setting up common serverless resources, lets you build and deploy your frontend app in the same stack, and has a feature called Live Lambda that - hold on to your chai latte - lets you attach a debugger to a deployed Lambda function running in AWS.
AWS's open-source take on a declarative framework specifically for deploying serverless applications is called AWS SAM, or Serverless Application Model. It had a slow start but has had an incredible cadence of pumping out features and quality-of-life additions in the last year or two and is now a very serious contender.
AWS CDK, Cloud Development Kit, is very different from our previous two candidates. It takes an imperative approach and lets you write your infrastructure code in the same language that you already use to write the rest of the application, and then synthesizes the code to CloudFormation to deploy it. A CDK app consists of building blocks called constructs, and these constructs can be shared and re-used. A perhaps unexpected aspect is that the nature of how you build your CDK apps makes it very easy to write actual unit tests for your infrastructure.
Architect is a heavily opinionated framework for building FWA's, Functional Web Apps. It uses AWS SAM under the hood but provides a layer on top with simplified abstractions that lets developers define and use AWS infrastructure without necessarily knowing what service is backing their "events" construct.
