Key concepts


In Infracost Cloud, organizations are used to manage API keys and associated settings. Every Infracost user has a default organization for personal use. We recommend creating a new organization for your company API key as in the future you'll be able to add other users to organizations.

API keys

Infracost API keys are associated with organizations and can be retrieved from the Org Settings page. If you revoke an API key and generate a new one in its place, you must update all CI/CD integrations and CLI installations that used the old API key.

Team management

From the Members page, you can invite your team members to join your organization. Currently only one role is supported:

  • Org Admin: they can do everything in the organization except delete the organization.

From the Members page, you can also change the Org Owner to another member. We treat the Org Owner as the main billing contact for the organization.


Repos, short for code repositories, is where your code lives in GitHub, GitLab or any other source control system. Repo is our top-level required grouping concept. If Infracost cannot detect it, you can provide it via new environment variables, otherwise cost estimates only show in the "All estimates" tab in Infracost Cloud (and not the dashboard, which shows pull request costs).

A repo contains one or more projects. Infracost Cloud lets you track how the costs of repos and projects change over time.


Projects are an optional sub-grouping concept within a repo. The majority of Infracost users will have repos that have many projects, these include:

  • code paths for mono repos, each path represents a deployment environment such as dev, stage, prod
  • workspaces, same idea as above but done using Terraform workspaces, e.g. for dev, stage, prod
  • Terraform or Terragrunt modules, which are components of a repo, e.g. core-api or data-stack

If you setup Infracost for a Terraform module repo, you will not need projects as there is no need for a sub-group.

Infracost auto-generates project names based on code paths, workspaces or Terraform/Terragrunt modules. The name appears in the CLI output and pull request comments and Infracost Cloud as shown below.

Customize project names

Sometimes, like when a path such as /tmp/plan.json is used, the project name can become long and hard to understand. In those cases you may want to set the name to something more understandable.

Project name flag

Use the --project-name flag with infracost breakdown and diff to cutomize the auto-generated project name. This flag can also be set in CI/CD integrations, where you can also use environment variables to customize the value.

export PROJECT_NAME=my-project-$MY_WORKSPACE

infracost breakdown --path plan.json --project-name $PROJECT_NAME

infracost diff --path plan.json --project-name $PROJECT_NAME

The --project-name flag should be set to the same value for both infracost breakdown and diff commands in CI/CD integrations. Otherwise the diff command will not be able to match the projects from the first breakdown run. Failing to do this results in odd diffs.

Config file

The name attribute in config-files provides the same functionality as the --project-name CLI flag.
