Making repeatable Azure deployments easy!

Farmer is an easy-to-learn library for rapidly authoring and deploying entire Azure architectures.

  • Infrastructure-as-code, done right. Simple code snippets allow you to rapidly construct complex topologies.
  • Idempotent deployments. Safely provision a template repeatedly and know that only changes will be applied.
  • Cross-platform. Runs on .NET Core on Windows, Mac or Linux.
  • Built on trusted technologies. Farmer uses Microsoft’s Azure Resource Manager (ARM) technology for deployments to Azure.
  • Commercial supported. Professional support plans for teams that wish to benefit from peace of mind and further improve the product.
  • Easy to learn, easy to understand code through a simple, strongly-typed and pragmatic DSL.

Already using ARM templates?

Farmer has you covered.

  • Farmer is completely backwards compatible with ARM templates. Farmer generates standard ARM templates so you can continue to use existing deployment processes.
  • Safely create dependencies between resources. Uses static typing to give confidence that your templates will work first time.
  • Easily access common properties of resources. No more fighting to concatenate cryptic strings!
  • Extensible API. Add new helpers and members as needed.
  • Open source and free. Farmer is free to use and modify. We welcome contributions to the project!

Why not Azure Resource Manager?

Azure Resource Manager is a service-side orchestrator, as such, Farmer does use ARM! It simply replaces the templating language with a statically-verifiable DSL to declare resources and comes with helper functions to perform common tasks. Farmer templates are around 5-8 times smaller than ARM templates, meaning they are quicker and easier to author, understand and maintain. Read more on the comparison page.

Creating a web application with a configured application insights and a linked storage account

Farmer Templates

These 20 lines of simple, readable and type-safe code are translated into 141 lines of JSON ARM template!

// Create a storage account with a container
let myStorageAccount = storageAccount {
    name "myTestStorage"
    add_public_container "myContainer"

// Create a web app with application insights that's connected to the storage account.
let myWebApp = webApp {
    name "myTestWebApp"
    setting "storageKey" myStorageAccount.Key

// Create an ARM template
let deployment = arm {
    location Location.NorthEurope
    add_resources [

// Deploy it to Azure!
|> Writer.quickWrite "myResourceGroup"
