HyperProbe, a YC S26 startup, introduces a novel approach to debugging live production environments. The system allows AI coding agents, such as Cursor and Claude, to safely insert read-only "probes" (virtual breakpoints) into running code. These probes capture exact variable values at the moment of failure, providing crucial data that traditional logs often miss.

This capability significantly reduces the time and effort engineers spend diagnosing issues by eliminating the need for slow log analysis or painful redeployments with added `console.log` statements. HyperProbe aims to resolve the challenge of debugging AI-generated code, which often lacks sufficient telemetry.

The system comprises an SDK integrated into the service and an MCP server that coding agents communicate with. The SDK enables on-demand telemetry capture without pausing or slowing down the live service. HyperProbe's team, with prior experience from HyperTest, focused on the hard problem of extracting runtime state safely from production systems.

HyperProbe supports Node.js, Java, and Python, and integrates with popular AI coding assistants. The probes are read-only, PII is redacted in-process, and the system can be self-hosted for enhanced security. The goal is to enable truly autonomous on-call agents that can diagnose and fix issues within minutes.
