Infracost

Infracost brings cloud cost estimates and FinOps guidance into infrastructure-as-code workflows, helping teams spot potential cost issues before deployment. It supports Terraform, CloudFormation, and AWS CDK projects across AWS, Azure, and Google Cloud. Infracost Cloud tracks more than 10 million price points and can display estimates and guidance in pull requests and IDEs. Its CI/CD integration can comment on cost changes, policy violations, and tagging issues introduced by a change. Cloud also supports custom guardrails, price books, and tagging policies; Issue Explorer can identify optimization opportunities and open pull requests with proposed fixes. Infracost AI combines AI provider billing, subscriptions, gateway logs, and agent telemetry to reconcile spending and model what-if scenarios for models and routing strategies. The free CI/CD plan includes 1,000 runs per month and Slack Community support. Starter costs $250 a month for 10,000 runs and email support. Estimates based on Terraform HCL alone may not resolve values available only at plan time; Terraform plan JSON is recommended for those cases.

Infracost connects cost review with infrastructure-as-code workflows and offers separate tools for AI spend analysis. Consider the plan limits and the Terraform plan-time estimate caveat when evaluating it.

It suits teams using infrastructure-as-code who want cost estimates and FinOps checks in development workflows. Teams working with AI provider spending may also find the listed reconciliation and scenario tools relevant.

Overview

Infracost puts cloud-cost estimates and FinOps feedback into infrastructure-as-code review, particularly for teams working across multiple cloud providers. Its strongest case is catching cost changes while developers are still reviewing infrastructure; Terraform estimates from HCL alone can miss values that only become available at plan time.

It covers Terraform, CloudFormation and AWS CDK projects on AWS, Azure and Google Cloud. Infracost Cloud says its pricing data spans more than 10 million price points, with estimates and FinOps guidance surfaced in pull requests and IDEs. Founded in 2021, the company is headquartered in San Francisco and is an official FinOps Foundation member.

Key features

Cost feedback in code review

CI/CD comments can show cost differences caused by a proposed change, alongside FinOps policy violations and tagging issues. That makes Infracost useful when engineering teams want cost review to be part of the same workflow as code review, rather than a separate check after deployment. For Terraform, however, HCL-only estimates cannot resolve values available only at plan time, such as data-source attributes or dynamic lookups. The recommended workaround is to use Terraform plan JSON for those cases.

Governance and optimization

Infracost Cloud supports custom guardrails, price books and tagging policies. Its Issue Explorer identifies optimization opportunities and can open pull requests with fixes. Cloud also includes visibility dashboards, team management and workflows, audit trails and autofix workflows. These features are more relevant to teams coordinating governance across developers than to an individual seeking a basic estimate.

AI spend analysis

Infracost AI combines provider billing, subscriptions, gateway logs and agent telemetry to reconcile AI spend and create what-if scenarios for models and routing strategies. Its integrations include Anthropic, OpenAI, Cursor, AWS Bedrock, Azure AI Foundry, Kong AI, LiteLLM, OpenRouter, Claude Code, Codex, OpenTelemetry and custom apps. This is a separate capability from infrastructure cost review, and may matter to organizations tracking both cloud infrastructure and AI usage.

Developer access and security

IDE support includes VS Code, Cursor, JetBrains, VSCodium, Eclipse Theia, Neovim, Zed and other editors; setup guidance also covers Claude Code, GitHub Copilot, Codex, Cursor and Gemini CLI. The CLI supports macOS, Windows and Linux. Project parsing happens locally, and no cloud credentials or secrets are sent to the API. Security safeguards include encryption in transit and at rest, least-privileged access controls, strong authentication, activity monitoring, backups and vulnerability management.

Pricing

Infracost uses a freemium, flat-rate model. Infracost CI/CD is free and includes 1,000 runs per month with Slack Community support. It is a practical starting point for teams wanting cost feedback in CI/CD, but the run cap may be restrictive as usage grows.

Starter costs $250 a month, billed $250/mo, and includes 10,000 runs per month and email support. It suits teams that have outgrown the free quota but do not need Cloud's broader governance tools.

Cloud costs $1,000 a month, billed $1,000/mo. It includes 10 admin seats; developer seats are available for an additional fee. Alongside FinOps policies and best practices, custom price books, cost guardrails and Issue Explorer, the plan adds autofix workflows, visibility dashboards, team management and workflows, and audit trails. The fixed monthly price and extra developer-seat charge are important considerations for larger teams.

Enterprise has custom pricing and is billed by contacting Infracost. It adds GitHub and GitLab Enterprise support, complex security requirements, SKU-level price overrides, reporting across business units, custom policies, SSO and SAML group mappings, service level agreements, and enterprise onboarding and support. It is aimed at organizations with those specific deployment, governance or support needs rather than teams seeking a published per-month rate.

Platforms

Infracost supports API, extension, Linux, macOS, web and Windows. Its CLI installation guidance covers macOS, Windows and Linux, while IDE integrations bring cost context into developers' editors.

Who it's for

Infracost is a strong fit for engineering and FinOps teams that want cloud cost changes reviewed before infrastructure is deployed, especially when they need pull-request feedback across AWS, Azure or Google Cloud. The free CI/CD tier offers a way to start, while Cloud is better suited to teams that need shared policies, optimization workflows and audit trails. It is less compelling for teams whose Terraform estimates depend heavily on plan-time values unless they can use plan JSON, or for buyers who only need straightforward spend monitoring.

Pros and cons

• Pro: Cost differences, policy violations and tagging issues can appear directly in pull requests, keeping review tied to the proposed infrastructure change.
• Pro: Cloud combines guardrails, optimization opportunities and autofix workflows for teams that need governance beyond estimates.
• Pro: Local project parsing and the stated handling of credentials reduce the need to send cloud secrets to the API.
• Con: Terraform HCL estimates cannot resolve values known only at plan time, so affected projects need Terraform plan JSON for those cases.
• Con: The free CI/CD plan stops at 1,000 runs per month, and Starter at 10,000; growth can mean moving to a paid plan.
• Con: Cloud's 10 admin seats do not include developer seats, which carry an additional fee.

Alternatives

For a broader comparison, browse Cloud Cost Management Software.

• Azure Application Insights is an option for readers considering a paid, usage-based Azure Monitor Logs plan with a free first 5 GB of monthly ingestion per billing account.
• CloudFix may suit readers focused on cloud savings scans: its free tier includes savings by category and full resource details for 30 days, and it also offers a $149 a month Starter plan.
• Teevity is worth considering for high-level monitoring across cloud spending, with a free service that includes a dashboard and daily email.
• AWS Billing and Cost Management is a free option for AWS-focused cost management, though some features have usage-based charges and Cost Explorer API requests and hourly granularity are charged separately.
• CloudBolt is an alternative for teams looking for a free core CMP covering up to 100 resources.
• Google Cloud Cost Management is a free option for Google Cloud customers, with no additional charge for its cost management tools; charges may apply for services used.
• Economize may fit smaller cloud-cost needs: its free plan supports one cloud provider, account and organization, up to $100k monthly cloud spend.
• Harness Cloud Cost Management is another freemium option; its paid fees are charged as a percentage of tracked cloud spend.

Verdict

Choose Infracost if your team wants cloud cost and FinOps checks embedded in infrastructure review, and Cloud if you need shared guardrails and optimization workflows. Look elsewhere if plan-time Terraform values make HCL estimates insufficient and you cannot use plan JSON, or if your priority is simpler cloud-spend monitoring without code-review integration.
