## What it is
Alchemy is a TypeScript-native Infrastructure-as-Code library for defining cloud resources (e.g., Cloudflare Workers, R2 buckets, Durable Objects) as memoized async functions that are created, updated, and deleted automatically. It runs in any JavaScript runtime with no external service, storing state locally and supporting an AI-first, embeddable workflow.

## Use cases
- provision cloudflare workers and r2 buckets from typescript
- infrastructure as code without yaml or hcl
- deploy a fullstack app to cloudflare with a single script
- create ephemeral preview environments per pull request
- define custom cloud resources as async functions
- manage cloud infrastructure state locally in git
- let an llm agent scaffold and deploy cloud resources

## When to choose
- you want IaC in pure TypeScript with no second language or external engine
- you primarily deploy to Cloudflare or JavaScript-friendly runtimes
- you want embeddable provisioning inside apps, tests, or serverless workflows
- you prefer local state files over a hosted state service

## When to avoid
- you need mature multi-cloud provider coverage like Terraform offers
- your team relies on declarative HCL/YAML workflows and existing Terraform modules
- you require long-term stability guarantees - the project is in beta (v2.0.0-beta)
