Infracost Cruise is an AI-native suite of tools designed to help platform and FinOps teams manage and reduce cloud waste by integrating cost-awareness throughout the infrastructure lifecycle. It offers a FinOps Context Engine that incorporates policies, custom price books, and budgets to ensure all teams operate from a unified system of record, enhancing the accuracy and learning capability of coding agents. Infracost Cruise includes agent toolkits that are embedded within everyday workflows, such as in coding agents, CI/CD pipelines, and remediation processes, to promote cost-efficient practices. The platform emphasizes "harness engineering," a practice of embedding quality and cost-optimization guardrails into agentic workflows, thereby reducing unnecessary cloud expenses. Infracost Dev extends these capabilities into major IDEs and coding agents, providing real-time pricing data to help engineers balance cost with other requirements. Additionally, Infracost Check and Infracost Fix offer solutions to ensure FinOps compliance and automate the resolution of FinOps violations, respectively, thereby minimizing cloud waste before infrastructure deployment.

Infracost has significantly redesigned its CLI to optimize interactions with AI coding agents such as Claude, resulting in a substantial reduction in token usage and API costs while maintaining accuracy. The redesign focused on improving the efficiency of the CLI's response to AI calls by implementing predicate pushdown and adopting TOON (Token-Oriented Object Notation) for output, which minimizes redundant data processing and reduces the token count. Benchmarks showed that these changes improved performance and cost efficiency while maintaining accuracy compared to previous methods that required more complex and costly scripting. The enhancements, originally driven by the opaque nature of agent usage, also offer benefits to human users by simplifying processes, allowing for more efficient terminal use, and facilitating better integration with CI scripts. The upgrade to version 2.0 reflects these significant changes in design and functionality, emphasizing efficiency and effectiveness for both AI and human callers.

Infracost Dev is a local agent designed to integrate seamlessly with various integrated development environments (IDEs) and coding agents to provide real-time cloud cost estimations and policy checks while writing infrastructure as code. This tool extends the capabilities of the previous VS Code extension by supporting a wide range of platforms, including Terraform, AWS CloudFormation, and CDK, and fetching price points from numerous services across AWS, Azure, and GCP. By operating locally, it ensures that code and data remain secure and that users receive immediate feedback without excessive API calls. Infracost Dev works alongside coding agents, offering a consistent rule layer and enabling engineers to focus on cost-effective infrastructure decisions without resorting to manual price lookups. It also supports FinOps practices when paired with Infracost Cloud, which allows for policy checks, custom price books, and cost guardrails, transforming coding agents into FinOps agents that automatically verify infrastructure changes against live policies. The tool is available in a free tier with a setup wizard that simplifies integration across various IDEs and coding environments.
