What is LightRun?
Lightrun is a developer observability platform that provides real-time, line-level code context across the entire Software Development Life Cycle (SDLC). It supercharges IDEs and AI Agents by allowing developers to debug and remediate software issues autonomously, powered by live runtime data. The platform enables engineers to add dynamic logs, metrics, and snapshots to live applications without stopping, redeploying, or modifying code.
Lightrun is designed for engineering teams that need to quickly pinpoint and resolve issues in complex, distributed environments, including production. It helps reduce Mean Time To Resolution (MTTR) by providing immediate visibility into application behavior, even for elusive bugs that only appear in specific environments. The tool integrates directly into popular IDEs like IntelliJ and Visual Studio Code, offering a seamless debugging experience for cloud-native, on-premise, containerized, and serverless applications.
