## What it is
Kotless is a Kotlin serverless framework that generates Terraform deployment code directly from application code, supporting its own DSL as well as introspection of Ktor and Spring Boot applications. It ships as a Gradle plugin that deploys web applications to AWS Lambda and Azure serverless platforms and supports local emulation and IDE debugging.

## Use cases
- deploy a Kotlin web app to AWS Lambda without writing Terraform
- convert an existing Ktor application into a serverless deployment
- run Spring Boot apps as serverless functions on AWS or Azure
- generate Terraform code from Kotlin application code
- locally emulate AWS environment for serverless debugging
- define scheduled events and routing with annotations for serverless apps

## When to choose
- you write Kotlin and want one-button serverless deployment to AWS or Azure
- you have existing Ktor or Spring Boot apps you want to run serverlessly
- you want Terraform generated automatically from your application code
- you prefer deployment integrated into your Gradle build

## When to avoid
- you deploy to platforms other than AWS or Azure
- your project is not on the JVM or does not use Gradle
- you need a framework with frequent updates and a large community
- you want full manual control over your Terraform infrastructure code
