CostLens is a software tool that connects to GitHub to measure the return on investment of AI coding tools by analyzing pull requests, cycle time, rework rate, and throughput. It solves the problem of not knowing whether AI tools are actually saving time and money. It sells to engineering teams, developers, and executives in companies of all sizes, particularly those using AI coding assistants. It is positioned as a bridge between token tracking and DORA metrics, providing an ROI report that leadership can act on. It is delivered as a SaaS platform with a free tier and optional proxy, SDK, and MCP server for deeper insights.
