Frequently asked questions (FAQ)

Does Lightrun change the state of my code?

We guarantee that our agent does not lead to or cause the execution of syscalls, exceptions or state modifications.

Using our secret sauce and our proprietary sandbox, we ensure application integrity and never write nor change state at the bytecode level.

For more information about security issues, we invite you to download our Security datasheet.

How does Lightrun affect our application server performance? How much of our resources does Lightrun consume?

Our agent is lazy and when idle, its consumption is negligible. Resources are only used when Lightrun actions have been added to the agent and are invoked. When invoked, performance footprint typically hovers around 10s of microseconds per log invocation. In any case, managers can limit agent consumption by customizing configurations.

How is information transferred between the different parts of the architecture?

The communication between all Lightrun components and the Lightrun
server is always established over industry-standard TLS 1.2 encrypted channels.
Certificate pinning is utilized both in the agent and the client. See the Security datasheet for more details.

Is Lightrun read-only?


Does Lightrun support audit trails and RBAC?

Yes, all the actions in the system are audited; additionally you can manage users with more granular out-of-the-box roles.

Do you support PII redaction and Blocklisting?

Yes. You can configure PII redaction for specific regular expressions, and you can customize blocklists for files, member variables, packages etc. in order to limit Lightrun from accessing those objects.

What privacy and security certifications does Lightrun have?

Lightrun is currently ISO-27001 compliant.

Our security policies are approved by Lightrun management at least annually and communicated to employees on a regular basis as part of the security awareness program, which covers various types of security-related training modules. 

See our Security datasheet for more information.

Can we store all data on our servers?

Lightrun offers a self-hosted deployment option. With this option, Lightrun is installed within your organizational network or through a private cloud, via Docker or Kubernetes. Your IT or DevOps team is responsible for the ongoing maintenance, as is the case for any other internal/local resource. In addition, all of your existing organizational security controls and policies automatically apply to all of Lightrun’s components.

See our Security datasheet for more information.

Do you have cloud instances in Europe so that the entire data flow can be geographically managed in Europe when needed?


What integrations do you currently support?

Using filebeats, fluentd or other similar data handlers, you can receive all Lightrun logs to your logging tool. Your metrics can be pushed to StatsD and we can export them to Prometheius for scraping. Additionally, we integrate with Slack, Datadog alerts and Sentry.

How does Lightrun compare to production debuggers?

Lightrun is a full observability platform, made by developers for developers, that covers all of the developer’s observability needs – debugging, code level alerting, feature verification, pinpoint profiling, context level logs and metrics.

We seamlessly integrate into the developers’ native environments, and make it easy for them to resolve issues quickly throughout all stages of the application lifetime.

With Lightrun’s Adaptive Observability organizations can reduce the amount of irrelevant data which is collected and paid for, and focus on the relevant data only – automatically change log levels, provide on-demand profiling, and continuously get insight with rich context.

What's the difference between Lightrun and reliability and exceptions monitoring tools?

Lightrun offers line-by-line visibility into your live code and not just exception data enrichment. This is a complete observability platform that covers all of the developer’s observability needs – debugging, code-level alerting, feature verification, pinpoint profiling, context level logs and metrics. 

Lightrun is fully integrated into the developers’ workflow, with a plugin native to their IDE and a CLI tool, empowering them to observe and debug their live applications.

Is Community actually free?

The Community plan is absolutely free, no strings attached including one plugin and one agent. No credit card is needed.

Is support included?

We offer chat and self-service support for Community customers. For Professional plan subscribers, we offer dedicated support for technical questions. Additionally, a support SLA is defined to guarantee you get the attention you deserve.

Do you offer a plan based on usage?

We offer customized plans based on your organization’s specific needs, typically based on the number of virtual machines, CPU, number of agents, the number of hosts etc.

Do I need a credit card to get started?

No. You can join the Community subscription without a credit card.
