infracost

Infracost is a cloud cost estimation tool that integrates with infrastructure-as-code platforms (Terraform, CloudFormation, AWS CDK) to show cost impacts before deployment. It works across AWS, Azure, and GCP, and can be embedded in terminals, IDEs, CI/CD pipelines, and AI coding agents.

What infracost is

Go-based CLI and ecosystem (LSP server, agent skills, IDE extensions) that parses IaC configurations and queries pricing APIs to generate cost breakdowns and policy compliance checks. Supports 1,100+ resource types across three cloud providers, with usage-based estimation and FinOps guardrail enforcement via optional SaaS backend (Infracost Cloud).

Quickstart

Get the infracost source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/infracost/infracost.gitcd infracost# follow the project's README for install & configuration

Best use cases

Pre-deployment cost visibility in CI/CD pipelines

Integrate into pull request workflows to surface cost diffs and policy violations before infrastructure changes are merged, enabling FinOps-aware code review.

Real-time cost feedback during IaC authoring

Use IDE extensions or AI agent skills to see cost implications inline while writing Terraform, CloudFormation, or CDK, reducing expensive surprises in production.

Centralized FinOps guardrails and tagging policies

Deploy Infracost Cloud to enforce consistent cost policies, regional preferences, and tagging standards across distributed engineering teams.

Implementation considerations

  • Pricing data accuracy depends on Infracost's upstream API feeds; validate cost estimates against vendor pricing for mission-critical budget forecasts.
  • SaaS features (Infracost Cloud) require API key provisioning and network egress to third-party servers; assess data residency and compliance requirements.
  • IDE extensions and agent skills are distributed across separate repositories; plan for dependency management and per-tool version alignment.
  • Cost estimation for usage-based resources (e.g., Lambda, S3) requires explicit usage assumptions; set baseline defaults and document why estimates may diverge from actual billing.
  • FinOps policy enforcement relies on consistent tagging and naming conventions; establish organizational standards before rolling out guardrails.

When to avoid it — and what to weigh

  • You need post-deployment cost tracking and billing reconciliation — Infracost estimates costs at plan/scan time; it does not ingest actual cloud bills or track month-to-date spend. Use AWS Cost Explorer, Azure Cost Management, or GCP Cost Management alongside it.
  • Your infrastructure uses custom or niche cloud resources — Although 1,100+ resources are supported, specialized or very new resource types may not be covered. Requires explicit verification against the supported resources list.
  • You operate in a strict air-gapped environment without external API access — Infracost requires access to cloud pricing APIs and (for SaaS features) Infracost Cloud. Offline-only deployments will have limited functionality.
  • You cannot or will not use a CLI tool or external SaaS dashboard — Infracost is primarily a CLI-driven ecosystem. While IDE integrations exist, core functionality centers on command-line interaction and optional cloud-hosted policy management.

License & commercial use

Apache License 2.0 (Apache-2.0). Permissive OSI-approved license permitting commercial use, modification, and distribution with attribution and liability/warranty disclaimers.

Apache 2.0 is a permissive license that permits commercial use, including in proprietary products and SaaS offerings, provided original copyright notices are retained. However, the optional Infracost Cloud SaaS backend likely operates under separate commercial terms; review infracost.io SaaS agreement for SaaS-specific use restrictions or costs.

Security considerations

CLI runs locally and parses IaC files in-process; no inherent remote code execution vector from parsing Terraform/CloudFormation alone. However, API keys (for cloud provider authentication and SaaS access) must be managed securely in CI/CD environments. Pricing API requests are made to Infracost-hosted or cloud-provider endpoints; network traffic should be inspected if subject to data residency or compliance constraints. No security audit results or vulnerability disclosure process mentioned in README; assess if this aligns with your risk posture.

Alternatives to consider

Terraform Cloud / Enterprise (Cost Estimation)

HashiCorp's native cost estimation for Terraform; tightly integrated but limited to Terraform and requires commercial license for advanced features.

Checkov (cost scanning module)

Open-source infrastructure scanning with some cost policy checks; broader security posture but less specialized in cost estimation and fewer cloud resources supported.

CloudHealth / Flexera

Commercial FinOps platform with post-deployment billing reconciliation and optimization; more comprehensive but requires live cloud account ingestion and licensing costs.

infracost FAQ

Does Infracost work offline or in air-gapped environments?
Not fully. The CLI requires access to cloud pricing APIs to generate estimates. SaaS features (Infracost Cloud) require egress to Infracost-hosted servers. Air-gapped deployments will have severely limited functionality unless you can cache pricing data locally.
What is the difference between Infracost CLI and Infracost Cloud?
CLI is open-source and free; it runs locally and generates cost estimates from the terminal. Infracost Cloud is an optional SaaS dashboard where teams define and enforce FinOps policies, guardrails, and tagging rules centrally. Both are complementary but Cloud is separate and likely has commercial licensing.
Can Infracost estimate costs for my existing infrastructure?
No. Infracost estimates costs from infrastructure-as-code (Terraform, CloudFormation, etc.) *before* deployment. It does not ingest live AWS/Azure/GCP bills or current resource usage. Use cloud-native cost tools (AWS Cost Explorer, Azure Cost Management, GCP Cost Management) to track live spend.
How accurate are the cost estimates?
Estimates are based on published cloud pricing and assume standard usage patterns. They may diverge from actual billing due to discounts, commitments, or usage variations not modeled. Always validate critical cost forecasts against vendor pricing or cost management tools.
