Infracost VS Code Extension

Infracost's VS Code extension shows you cost estimates for Terraform right in your editor! It also surfaces FinOps policies and tagging issues so you can catch problems before they reach production.

Features

Cost estimates

Inline cost estimates

See cost estimates as code lenses directly above Terraform resource definitions. Costs update as you edit.

Resource details sidebar

Click a code lens to open the resource details panel, showing a full cost component breakdown, FinOps policy violations, and tagging issues.

FinOps policies and tag issues

The extension highlights FinOps policy violations (with risk, effort, and potential savings) and tag policy issues directly in the sidebar. Blocking violations are clearly marked.

CloudFormation support

In addition to Terraform (.tf) files, the extension supports CloudFormation templates in YAML and JSON.

Get started

1. Install the extension

Download the .vsix file for your platform from the latest pre-release. Then install it manually:

code --install-extension infracost-0.2.35-darwin-arm64.vsix

Or in VS Code: open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P), run Extensions: Install from VSIX..., and select the downloaded file.

2. Login to Infracost

Open the Infracost sidebar and click Login to Infracost. This will open a browser window to authenticate your editor with your Infracost account.

3. Open a Terraform project

Open a workspace containing Terraform files. The extension will start the language server and begin scanning your project. Cost estimates will appear as code lenses above resource blocks.

4. Cost estimates in pull requests

Use our CI/CD integrations to add cost estimates to pull requests, giving your team visibility into cloud costs as part of your workflow.
