Which Lightrun plan should you pick?

Start with Free Plan to evaluate Lightrun AI SRE, then upgrade to Pro or Enterprise for automation, governance, integrations, and enterprise access controls.

Free Plan

Good for teams evaluating Lightrun AI SRE with Slack, the web UI, conversational assistance, core investigations, limited connectors, and multi-user management.

Pro Plan

Good for teams needing automatic alert investigations, organizational knowledge memory, role-based access control, or runtime-context features such as multi-instance debugging and IDE plugins.

Enterprise Plan

Good for organizations needing SSO, SCIM, SAML, audit logs, broader integrations, PII redaction, custom connectors, and enterprise support.

Lightrun Use Cases

Debug live production applications

Add dynamic logs, snapshots, metrics, and traces to running applications from supported IDEs or the CLI.

Outcome: Investigate issues without redeployment, restart, or reproducing the problem locally.

Resolve production incidents

Use AI SRE workflows to gather runtime evidence, triage issues, prove root causes, and validate fixes.

Outcome: Reduce time to resolution with evidence-based incident handling.

Collaborate across engineering teams

Share runtime logs, snapshots, traces, and incident context across development, SRE, operations, and QA.

Outcome: Create a shared view of live system behavior.

Standardize incident response

Create Debug Runbooks containing repeatable diagnostic steps, conditions, snapshots, and runtime data collection.

Outcome: Capture consistent evidence before important production states disappear.

Ground AI coding assistants in runtime context

Connect supported AI assistants through Lightrun MCP to inspect values, call stacks, execution duration, and metrics.

Outcome: Validate debugging hypotheses against live application behavior.

Workflow Ideas with Lightrun

Production incident investigation

  1. 1Receive or detect a production issue
  2. 2Add runtime logs, snapshots, or metrics at the suspected code path
  3. 3Analyze the captured evidence and validate the root cause

Repeatable support diagnosis

  1. 1Create a Debug Runbook with diagnostic conditions and evidence to capture
  2. 2Launch a runbook case against the affected application
  3. 3Share the captured results with developers for analysis

AI-assisted runtime debugging

  1. 1Connect an AI assistant to Lightrun through MCP
  2. 2Ask the assistant to investigate a live application issue
  3. 3Use runtime evidence to produce a diagnosis and next action

Cons

  • −Initial Learning Curve: New users may require some time to familiarize themselves with the tool’s functionalities.
  • −Integration Limitations: While it supports major IDEs, there might be limitations with less common development environments.
  • −Resource Utilization: In complex applications, extensive use of features might impact system resources.

Limitations & when to consider alternatives

Known limitations

  • Debug Runbooks have limited availability. The feature is documented as limited availability, requires the Enterprise plan, and requires contacting Lightrun Support.
  • Actions expire after 10 days. Lightrun actions are retained for 10 days after expiration and then automatically deleted.
  • Runtime resource quotas apply. Lightrun limits CPU, memory, I/O, log output, and other resources to protect application performance.
  • VSCode.dev has feature limitations. The browser-based VSCode.dev plugin does not support snapshot import/export, Log Collector, or certificate pinning for WebSockets.
  • Some runtime and platform combinations are unsupported. Documented limitations include certain older Python and Node.js versions, CentOS 7.0, Python Alpine Linux configurations, and babel-watch applications.

Look elsewhere when

  • You need a native mobile application.
  • You need a general-purpose browser extension.
  • You need built-in code generation or editing.
