HyperProbe lets your coding agent debug production by reading the actual variable values on the failing line, without adding a log or redeploying. When code breaks in prod and the value you need was never logged, your agent is stuck guessing from logs. HyperProbe lets it drop a read-only probe on the exact line in your running service, capture the real state when live traffic hits it, and diagnose from evidence instead of inference. Try it: hyperprobe.co What it does: Your agent places a probe on one line in the live service, over MCP It captures the local variables and call stack the next time real traffic hits that line No redeploy, no restart, nothing pauses Read-only. Redaction happens in-process, before anything leaves your container Self-host option so no captured state leaves your network Supports Node, Java, and Python The bugs this is for are the quiet ones. A call times out and returns null, null gets read as zero, a user sees a wrong balance. An upstream API starts returning a number as a string. None of them throw, most return 200, and the value that explains them was never written down. Those are the incidents that eat an afternoon and often get filed as a known quirk.
