Infracost

Overview

Infracost puts cloud-cost estimates and FinOps feedback into infrastructure-as-code development, making it a strong fit for engineering teams that want cost changes reviewed alongside code. It is most useful when deployment costs can be estimated before release; Terraform HCL estimates cannot resolve values known only at plan time.

It supports Terraform, CloudFormation and AWS CDK across AWS, Azure and Google Cloud. The company was founded in 2021 and is headquartered in San Francisco.

Key features

Cost feedback in development

Infracost Cloud tracks more than 10 million cloud price points and can show estimates and FinOps guidance in pull requests and IDEs. CI/CD comments can highlight cost changes, policy violations and tagging issues introduced by a change. That gives developers and reviewers a chance to address cost implications before deployment, rather than relying only on later billing review.

Governance and optimization

Cloud supports custom guardrails, price books and tagging policies. Issue Explorer finds optimization opportunities and can open pull requests with fixes. Dashboards, audit trails, team workflows and autofix workflows make Cloud the tier for teams that need shared cost governance; the free and Starter plans focus on CI/CD runs instead.

AI spend analysis

Infracost AI combines provider billing, subscriptions, gateway logs and agent telemetry to reconcile AI spend and model what-if scenarios for models and routing. Its integrations include Anthropic, OpenAI, Cursor, AWS Bedrock, Azure AI Foundry, Kong AI, LiteLLM, OpenRouter, Claude Code, Codex, OpenTelemetry and custom apps. This extends the product beyond infrastructure estimates for teams managing AI usage, though those needing only cloud cost feedback may not need this additional analysis.

Security and estimate limits

Project parsing happens locally, and cloud credentials and secrets are not sent to the API. The privacy policy describes encryption in transit and at rest, least-privilege access, authentication, activity monitoring, backups and vulnerability management. One important limitation: Terraform HCL alone cannot resolve values known only at plan time, such as data-source attributes or dynamic lookups. Teams with those configurations should use Terraform plan JSON for more accurate estimates.

Pricing

Infracost uses a flat-rate model for paid tiers, with a free CI/CD option and paid plans from $250/mo.

• Infracost CI/CD: free, with 1,000 runs per month and Slack Community support. It suits smaller teams validating the workflow, but the run cap and community-only support may constrain regular use.
• Starter: $250 a month (billed $250/mo), with 10,000 runs per month and email support. It is the step up for teams that need substantially more CI/CD capacity, but does not include the governance and optimization features bundled into Cloud.
• Cloud: $1,000 a month (billed $1,000/mo), with 10 admin seats; developer seats cost extra. It adds FinOps policies and best practices, custom price books, Cost Guardrails, Issue Explorer, autofix workflows, visibility dashboards, team management and workflows, and audit trails. This is the relevant plan for teams that need these shared controls, but the additional developer-seat fee matters when broad access is required.
• Enterprise: custom pricing. It adds GitHub and GitLab Enterprise support, SKU-level price overrides, business-unit reporting, custom policies, SSO and SAML group mappings, service-level agreements, and enterprise onboarding and support. It suits organizations with those security, reporting or support requirements; smaller teams may not need its enterprise-specific capabilities.

Platforms

Infracost lists API, extension, Linux, macOS, web and Windows platforms. CLI installation covers Linux, macOS and Windows. IDE support includes VS Code, Cursor, JetBrains, VSCodium, Eclipse Theia, Neovim, Zed and other editors, with setup guidance for Claude Code, GitHub Copilot, Codex, Cursor and Gemini CLI. That range suits teams with varied editor preferences.

Who it's for

Infracost is best for engineering and FinOps teams that want infrastructure cost changes, policy checks and optimization opportunities close to the code review process. Cloud is a better match for teams needing shared governance; smaller groups can start with the free run allowance or Starter. Teams whose cost inputs depend heavily on values available only at plan time should factor in the HCL limitation and use plan JSON.

Pros and cons

• Pro: Pull request comments connect cost differences, policy violations and tagging issues to the change that introduced them.
• Pro: Cloud combines guardrails, price books, optimization issues and autofix workflows for teams seeking more than estimates.
• Pro: Local project parsing avoids sending cloud credentials or secrets to the API.
• Con: Terraform HCL estimates cannot resolve plan-time-only values, so some configurations need plan JSON.
• Con: Cloud's 10 admin seats do not include unlimited developer access; additional developer seats cost extra.

Alternatives

For a broader comparison, see Cloud Cost Management Software.

• Teevity is worth considering for high-level cost monitoring, a dashboard and daily email that bring cloud spending together.
• AWS Billing and Cost Management is a free-plan option for AWS-focused users, though some features and Cost Explorer API requests or hourly granularity carry separate usage-based charges.
• Google Cloud Cost Management is a no-additional-charge option for Google Cloud customers, with charges potentially applying to services used.
• Economize offers a free plan limited to one cloud provider, account and organization, with up to $100k monthly cloud spend.
• Flexera One IT Asset Management is another option for buyers evaluating IT asset management.
• CoreStack FinOps offers FinOps governance as an individual product, in a bundle or with unlimited CoreStack Assessments, with quote-based pricing.
• Vantage is an alternative with a Starter tier capped at $2,500 cloud spend, 3 users and 6 months of data retention, or a $30 a month Pro tier capped at $7,500 cloud spend, 5 users and 6 months of retention.
• CloudFix is another freemium option for teams comparing cloud-cost tools.

Verdict

Choose Infracost if your engineering team wants cost estimates and FinOps checks to travel with infrastructure changes, and Cloud if you also need shared policies and optimization workflows. Look elsewhere or plan to use Terraform plan JSON if HCL-only estimates cannot capture values your infrastructure depends on; budget carefully for developer access if you choose Cloud.
