Devin supports Windows as a build and session platform. Windows environments use the same bash shell (Git Bash) as Linux, so most blueprint commands work across both platforms without modification.
Windows support is currently available on a limited basis. If you’re interested in trying out Windows with Devin, please contact us to learn more and get access.

How it works

Windows support is built on the same declarative configuration system as Linux. The key difference is the runs-on field in your blueprint, which tells Devin which platform to build and run on. Since both platforms use bash, you can write the same shell commands on Linux and Windows. The main differences are the file system layout and available package managers:
AspectLinux (default)Windows
Home directory/home/ubuntu/c/Users/Administrator
Repo directory~/repos/<repo-name>/c/Users/Administrator/repos/<repo-name>
Package managerapt-getchoco, winget, or direct installers

Writing Windows blueprints

Single-platform blueprint

If your repository only targets Windows, use runs-on: windows at the top level:
runs-on: windows

initialize:
  - name: "Install Node.js"
    uses: github.com/actions/setup-node@v4
    with:
      node-version: "20"

  - name: "Install build tools"
    run: |
      choco install visualstudio2022buildtools -y
      choco install python --version=3.12 -y

maintenance: |
  npm install

knowledge:
  - name: lint
    contents: npm run lint
  - name: test
    contents: npm test
  - name: build
    contents: npm run build

Multi-platform blueprint

To build the same repository for both Linux and Windows, use the multi-block YAML format. Each block declares its own runs-on label:
- runs-on: default
  initialize: |
    curl -LsSf https://astral.sh/uv/install.sh | sh
    apt-get update && apt-get install -y build-essential

  maintenance: |
    uv sync

  knowledge:
    - name: test
      contents: uv run pytest

- runs-on: windows
  initialize: |
    choco install python --version=3.12 -y

  maintenance: |
    uv sync

  knowledge:
    - name: test
      contents: uv run pytest
Each block produces a separate snapshot build for its platform. Sessions boot from the platform-specific snapshot.

The runs-on field

The runs-on field maps to a registered machine config on your account:
ValuePlatform
default or linuxLinux (default platform)
windowsWindows
You can specify runs-on as a string or a list:
# Single platform
runs-on: windows

# Multiple platforms in one block (same commands run on each)
runs-on: [default, windows]
When a block lists multiple platforms, the build system creates one snapshot per platform using the same commands.
The list syntax runs identical commands on every platform in the list. Only use it when commands are truly cross-platform (e.g., npm install, uv sync). For platform-specific commands (like apt-get on Linux or choco on Windows), use the multi-block format instead — one block per platform.

Windows session behavior

Shell

Windows sessions use Git Bash as the default shell — the same bash shell used on Linux. Standard bash syntax works on both platforms:
- run: |
    export MY_VAR="hello"
    echo $MY_VAR

Paths

Windows uses Git Bash path format (/c/... instead of C:\...):
# Linux paths
- run: cp config.json ~/.config/myapp/config.json

# Windows paths (Git Bash format)
- run: cp config.json /c/Users/Administrator/.config/myapp/config.json

Secrets

Secrets are available as environment variables during sessions using standard bash syntax ($SECRET_NAME):
maintenance:
  - name: "Configure registry"
    run: |
      npm config set //registry.npmjs.org/:_authToken $NPM_TOKEN

File attachments

On Windows, uploaded files are written to /c/Users/Administrator/.files/ instead of /home/ubuntu/.files/.

Blueprint tips for Windows

Installing tools

Use choco (Chocolatey), winget, or direct download scripts:
initialize:
  - name: "Install Chocolatey packages"
    run: |
      choco install git -y
      choco install nodejs-lts -y
      choco install python --version=3.12 -y

  - name: "Install with winget"
    run: |
      winget install --id Microsoft.DotNet.SDK.8 --accept-source-agreements --accept-package-agreements

Common patterns

.NET project:
runs-on: windows

initialize:
  - name: "Install .NET SDK"
    run: |
      winget install --id Microsoft.DotNet.SDK.8 --accept-source-agreements --accept-package-agreements

maintenance: |
  dotnet restore

knowledge:
  - name: build
    contents: dotnet build
  - name: test
    contents: dotnet test
  - name: lint
    contents: dotnet format --verify-no-changes
Visual Studio / C++ project:
runs-on: windows

initialize:
  - name: "Install Visual Studio Build Tools"
    run: |
      choco install visualstudio2022buildtools -y
      choco install visualstudio2022-workload-vctools -y

maintenance: |
  msbuild /t:Restore MySolution.sln

knowledge:
  - name: build
    contents: msbuild MySolution.sln /p:Configuration=Release
  - name: test
    contents: vstest.console.exe bin/Release/Tests.dll
