The extraordinary simple, performant, and extensible custom AWS Lambda runtime for Clojure.

**Holy Lambda supports multiple backends**

  - [Babashka](https://github.com/babashka/babashka),

  - Native Clojure (GraalVM compiled), 

  - Clojure (much faster than official AWS Java runtime),

## Goals

  - **Low cold starts** - Clojure goes fast on AWS Lambda.

  - **Multiple backends support** - Unified runtime for Clojure.

  - **Minimal API** - Just stuff that gets the job done.

## Non-Goals

  - **Tight integration with deployment tools** - I don't want to do this.

  - **ClojureScript support** - there is no additional value HL may provide for Clojurescript. Use either [nbb](https://github.com/babashka/nbb) or [shadow-cljs](https://github.com/thheller/shadow-cljs) with advanced compilation.

## Companies & Inviduals using Holy Lambda?

  - [nextdoc.io](https://nextdoc.io) - 6 native lambdas: api-gateway custom authorizer, file access control, openapi data source etc.

  - [scalably.ai](https://scalably.ai) - 14 native lambdas: xml transformations, sftp interactions, message routing, encryption etc.

  - [retailic](https://retailic.com/) - native lambda that uses compatibility layer with ring, regular Clojure api on ARM64 

  - [day8](https://www.day8.com.au/)

  

## Extensions

  - [holy-lambda-ring-adapter](https://github.com/FieryCod/holy-lambda-ring-adapter) - Supports running full featured Ring apps on AWS Lambda
