Lightrun gives engineering teams a way to investigate running applications by adding dynamic logs, snapshots, metrics and traces at runtime, without redeploying. Developers can also capture variables and stack frames, evaluate expressions in running code, and debug across Kubernetes pods and other instances. Its supported languages include Java, JavaScript, TypeScript, Python and .NET. The product is aimed at teams that need runtime evidence from live services; it is less suited to buyers seeking a free debugging plan, since Runtime Context is sold through custom-priced plans.

The range of ways to request runtime context is a notable part of the product. Developers can work through IDE plugins and a CLI, or request context through APIs and MCP workflows. Lightrun lists integrations with source-control services such as GitHub, Bitbucket and GitLab, and observability tools including Datadog, Grafana, Prometheus, Splunk and Sentry. Deployment options include cloud and self-hosted, while the Enterprise plan adds on-prem deployment. This makes Lightrun relevant to teams working across varied development and observability environments, though buyers should confirm that their specific workflow fits the listed integrations and deployment options.

Pricing and access controls draw a clear line between the plans. The Pro Plan — Runtime Context includes multi-instance debugging, MCP integration, dynamic telemetry and IDE plugins. The Enterprise Plan — Runtime Context adds on-prem deployment, custom SSO integrations, role-based access control and 24/7 support. According to Lightrun's published plan information, Runtime Context pricing is custom and requires contacting sales; its separate AI SRE Free Plan does not apply to this debugging product. PII redaction and blocklists are available to protect sensitive data. Choose Lightrun if runtime investigation without redeployment is central to your work; consider alternatives if you need transparent self-serve pricing or a free debugging tier.
