## What it is
Klotho is an open-source CLI tool that transforms plain application code into cloud-native code using in-code annotations, generating infrastructure for AWS (and nominally Azure/GCP) via Pulumi. It exposes web APIs, persists data to databases, and packages static assets to CDNs with minimal code changes.

## Use cases
- turn a plain node app into a serverless AWS deployment
- generate infrastructure-as-code from code annotations
- expose a web API on AWS Lambda without writing Terraform
- persist app data to a cloud database automatically
- deploy static assets to a CDN from code
- adopt cloud-native architecture without rewriting the app

## When to choose
- you want infrastructure-from-code with minimal annotation-driven changes on AWS
- you prefer generated Pulumi/Terraform over hand-writing IaC
- you want a superset of monolith/microservices/serverless deployment styles

## When to avoid
- you need actively maintained tooling - the project is no longer in active development
- you target clouds other than AWS in production
- you need fine-grained manual control over your infrastructure definitions
