Polar Signals is a continuous profiling platform using eBPF to collect low-overhead performance data from running applications in production without requiring code changes. Its homepage frames the product partly around AI coding tools, arguing that "LLMs are great at writing code, but blind to how it runs in production," and offers an MCP server so agents like Claude Code, Cursor, and Copilot can query line-level execution data directly. It claims sub-1% overhead and includes a customer testimonial describing a specific finding — 55% unexpected CPU usage identified within a 15-minute discovery window — alongside SOC 2, NVIDIA Inception Program, and Google Cloud Marketplace credentials.
