Since its launch, Infracost has emerged as a powerful tool for automating cost estimation in Infrastructure as Code (IaC) environments, contrasting with the AWS Cost Calculator, which is more suited for manual, one-off cost estimates for new applications. The deprecation of AWS's simple cost calculator has left the AWS Pricing Calculator as the primary tool for estimating costs, which requires manual input to recreate infrastructure setups. Infracost, on the other hand, can automatically generate cost estimates from existing Terraform code and integrates seamlessly into CI/CD workflows, providing detailed cost breakdowns and estimates of changes in real-time. It supports multiple clouds, including AWS, Microsoft Azure, and Google Cloud Platform, and allows the use of enterprise discounts, while also offering various integration options, such as with GitHub and Jira. Infracost's capacity to automate cost estimation without additional user effort makes it particularly beneficial for engineers aiming to understand the financial impact of code changes before production.
