Alchemy

Alchemy is an embeddable, TypeScript-native Infrastructure-as-Code (IaC) library for modeling Resources that are Created, Updated and Deleted automatically.

Unlike similar tools like Pulumi, Terraform, and CloudFormation, Alchemy is implemented in pure ESM-native TypeScript code.

Resources are simple memoized async functions that can run in any JavaScript runtime, including the browser, serverless functions and durable workflows.

Features

• JS-native - no second language, toolchains, processes, services, etc. to lug around.
• Async-native - resources are just async functions - no complex abstraction to learn.
• ESM-native - built exclusively on ESM, with a slight preference for modern JS runtimes like Bun.
• Embeddable - runs in any JavaScript/TypeScript environment, including the browser!
• Extensible - implement your own resources with a simple function.
• AI-first - alchemy actively encourages you to use LLMs to create/copy/fork/modify resources to fit your needs. No more waiting around for a provider to be implemented, just do it yourself in a few minutes.
• No service - state files are stored locally in your project and can be easily inspected, modified, checked into your repo, etc.
• No strong opinions - structure your codebase however you want, store state anywhere - we don't care!
