DefangLabs/defang

Take your app from Compose to a secure and scalable deployment on your favorite cloud in minutes.
How It Works
1. **You write** a standard Docker **Compose** file
2. **Defang CLI** validates your Compose project and uploads the project to storage in your AWS/GCP account
3. **CD runs in your cloud** — a deployment task spins up in your AWS/GCP account
4. **Infrastructure is created** — containers, DNS, load balancing, and roles are provisioned
5. **Monitor** the deployment and tail or query runtime logs with the Defang CLI
Your code and secrets never leave your cloud account. Defang orchestrates the deployment, but everything runs in your infrastructure.
Defang CLI
The Defang Command-Line Interface (CLI) is designed for developers who prefer to manage their workflows directly from the terminal. It offers full access to Defang’s capabilities, allowing you to build, test, and deploy applications efficiently to the cloud.
Deploying with Defang
If you already have a Docker Compose file, create a new stack and then deploy it. For example:
Defang MCP Server
The Defang Model Context Protocol (MCP) Server is tailored for developers who work primarily within integrated development environments (IDEs). It enables seamless cloud deployment from supported editors such as Cursor, Windsurf, VS Code, VS Code Insiders and Claude delivering a fully integrated experience without leaving your development environment.
Claude Code Plugin
Install the Defang plugin for Claude Code to deploy directly from any Claude Code session — no CLI required upfront:
After installing, use /defang:deploy to guide you through deploying your project. The Defang MCP server activates automatically once the Defang CLI is installed.

- Built-in support for MCP Server — the Defang MCP Server makes cloud deployment as easy as a single prompt. Learn more
- Samples that show how to deploy an app using the Defang Pulumi Provider.
Getting started
- Read our Getting Started page
- Follow the installation instructions from the Installing page
- Take a look at our Samples in Golang, Python, and Node.js that show how to accomplish various tasks and deploy them
- Try the AI integration by running defang generate
- Start your new service with defang compose up
Installing
Install the Defang CLI from one of the following sources:
- Using the Homebrew package manager DefangLabs/defang tap:
- Using a shell script:
- Using Go:
- Using the Nix package manager:
- with Nix-Env:
- or with Flakes:
Released tags are available from our Cachix binary cache, so
you can download the CLI instead of compiling it. If you have Cachix installed, run
cachix use defanglabs; otherwise add these lines to /etc/nix/nix.conf (or
~/.config/nix/nix.conf if you are a trusted user):
Then install a tagged version, e.g. nix profile install github:DefangLabs/defang/v3.14.1#defang-cli.
