Lightrun

Lightrun is a developer-native observability and live-debugging platform. Language agents embedded in a running JVM, Python, Node.js or .NET process accept dynamic actions — logs, snapshots, counters, tic-toc timings and custom metrics — placed on a file and line while the application keeps serving traffic, so engineers can inspect production behavior without redeploying, restarting or attaching a traditional debugger. The platform is driven from JetBrains, VS Code and Visual Studio plugins, a Java CLI, a bearer-authenticated Public REST API, and a published MCP server that gives AI coding assistants live runtime context. Around that core it adds agent-pool RBAC, PII redaction, SSO and SCIM provisioning, and a Dynamic SBOM surface that reports which third-party packages are actually reachable at runtime.

Lightrun publishes 1 API on the APIs.io network: Public API. Tagged areas include Company, Developer Tools, Observability, Debugging, and Monitoring.

The Lightrun catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Lightrun’s developer surface includes documentation, API reference, getting-started guide, engineering blog, pricing, signup flow, changelog, and 28 more developer resources.
