Reduce Observability Costs
with Runtime Precision
Always-on telemetry creates noise, cost, but leaves blind spots.
Lightrun lets engineers generate precise runtime signals on demand.
I’m investigating. I’ll start with runbooks and then correlate telemetry with the deployment and downstream behavior.

Always-on telemetry creates waste.
Precision telemetry removes it.
Harness high-signal telemetry by adding dynamic, ephemeral logs and traces into running software.
Dynamic data
precision
Inject dynamic logs around an incident’s site surface that disappear after diagnosis to keep data footprint lean.
High-fidelity
context
Gain richer insights capturing snapshots of full variable states and stack traces to deliver maximum context with minimal overhead
Intelligent signal
boosting
Tune out noise by prioritizing high-value signals so your team can focus on actionable insights while staying compliant.
Engineers stay in control
Telemetry is controlled at runtime by engineers. Visibility stays high while costs remain predictable.
Get full visibility
with lower overheads
Lightrun uses dynamic instrumentation to provide Runtime Context on key areas of investigation, delivering clarity without broad-spectrum logging.
Reduce reliance
on static logging
End the need to add costly logs into every deployment. Lightrun injects instrumentation on-demand, keeping your static costs fixed, even as system complexity grows.
Run efficient investigations
across environments
Lightrun captures logs, traces, and snapshots through a unified runtime pipeline across QA, staging, and production, reducing duplication while preserving governance.
Engineered for production scale
Built for safe, controlled runtime instrumentation across every environment.
Every injection, snapshot, and rnAI action is logged for accountability.
On-demand, read-only execution with u003cstrongu003esnapshot isolationu003c/strongu003e, without impact on production systems.
Works across all the platforms, tools, and environments in your team’s stack.
Run across Kubernetes, serverless, u003cstrongu003eon-premu003c/strongu003e, and bare metal, from canary to production.
Prompts that are grounded in live runtime context, adapting to situations, not static workflows.
Accessible within each platforms your team already uses.
Control access with SSO, SAML, and RBAC to govern runtime evidence creation across environments.
Enterprise-grade security
Built to meet enterprise security and compliance standards, with full access controls.
