Cloud-native development demands a new approach to building, launching, and observing cloud apps. Mantil is a modern open-source framework for writing serverless apps in Go. It allows you to quickly create and deploy applications that use AWS Lambda over a command line interface.

There are many serverless tools out there focused on building infrastructure. In Mantil, developers write pure Go code without any notion of AWS or Lambda. Therefore, you don't need an upfront understanding of the complex AWS ecosystem and tooling.

Get the feeling of local development while using real services in the cloud. With built-in support for multiple development stages and parallel lines of deployment, you still keep your private development sandbox. But in the serverless world, all environments are essentially the same environments.

Many developers who have played with AWS Lambda complain about frustrating build experiences where you need to make a number of steps manually. With mantil watch app is deployed automatically on every save. Moreover, it is done in seconds, so fluid development workflow is preserved.

Mantil also supports code testing via standard go tests or by invoking a specific function and getting logs instantly during function execution (not after the function is completed). And much more.

To get started with Mantil, you need to have installed Go and access to AWS account. Follow these few simple steps, and you will be up and running in minutes.

# Install Mantil CLI
$ brew tap mantil-io/mantil
$ brew install mantil

# Install Mantil Node on AWS
$ mantil aws install --aws-profile=my-named-profile

# Create your first Mantil project (it just creates project structure)
$ mantil new my-project
$ cd my-project

# Deploy your project to development stage
$ mantil stage new development

And that's it, you've created your first serverless app using Mantil. Read Getting Started tutorial or watch the accompanying video to dive deep into each step and to learn more about how to work with Mantil.

Mantil CLI is also available on Windows and Linux via direct download.
