Lightrun: Production Debugging May 2026

Last updated: 2026-05-31

Live debugging adds logs and metrics to production without redeployment.

About Lightrun

Lightrun is an AI-native reliability engineering platform that enables developers and AI agents to autonomously prevent and remediate software issues across the SDLC. At its core is a Runtime Context Engine that instruments live production applications at the line-of-code level — adding dynamic logs, snapshots, and metrics without restarts or redeployments. In 2026, Lightrun expanded beyond developer observability into a full AI SRE platform, recognized in the Gartner Market Guide for AI Site Reliability Engineering Tooling. Its patented Sandbox allows safe interaction with production environments, enabling the AI to generate missing runtime evidence on demand, validate hypotheses against live execution data, and prove root cause analyses before fixes are deployed. Lightrun also offers Debug0, an AI debugging agent that resolves complex issues across integration, QA, staging, and production environments. The platform supports monoliths, microservices, Kubernetes, Docker Swarm, ECS, serverless, and Big Data workers. Enterprise customers include AT&T, Citi, Microsoft, Salesforce, UnitedHealth Group, SAP, ICE/NYSE, ADP, HPE, and Booking Holdings.
