Cost.dev is a CLI tool designed for coding agents to provide cost-aware cloud infrastructure optimization, reducing token usage and API costs. It shifts FinOps left by integrating cost estimates into agent workflows and IDEs, combining deterministic price lookups with natural language capabilities. Its focus on agent-first CLI design is a novel approach to an emerging problem.

Target audience: platform engineers, devops, infrastructure engineers, backend devs
