Overview
Lightrun
Lightrun is a developer-centric observability platform that lets you debug and monitor your applications while they are running in production. Instead of waiting for a full CI/CD cycle to add a single log line, you can insert virtual 'action points' like logs, snapshots, and metrics directly into your live code. This approach helps you identify the root cause of production issues instantly without affecting the end-user experience or requiring a service restart.
You can use the platform across various environments, including Kubernetes, serverless, and on-premise setups. It integrates directly into your existing IDE, allowing you to troubleshoot complex distributed systems from the comfort of your local development environment. By providing real-time visibility into code execution, it eliminates the guesswork often associated with intermittent bugs and performance bottlenecks in high-scale environments.
Memfault
Memfault gives you the visibility you need to manage connected hardware at scale. Instead of flying engineers to the field or relying on vague customer reports, you get automated crash reports and performance metrics directly from your devices. You can monitor battery life, memory usage, and connectivity stability across your entire fleet from a single cloud-based dashboard.
The platform simplifies the entire maintenance lifecycle by allowing you to push over-the-air (OTA) updates to specific groups of devices. You can catch regressions before they hit your whole user base by using staged rollouts. Whether you are building a smart home product or industrial sensors, it helps you reduce RMAs and improve product reliability without manual debugging.
Overview
Lightrun Features
- Dynamic Logging Add log lines to your live application instantly to capture specific variable values without redeploying your code.
- Virtual Snapshots Capture the full call stack and local variables at specific code lines without pausing the execution of your program.
- Real-time Metrics Insert custom counters and timers into your production environment to measure performance and track specific code paths.
- IDE Integration Debug your remote applications directly from IntelliJ, VS Code, or PyCharm using a familiar interface and workflow.
- Conditional Breakpoints Set specific conditions for your logs and snapshots so you only capture data when specific error criteria are met.
- Security Governance Control exactly who can add actions to your code and redact sensitive data automatically to maintain strict compliance.
Memfault Features
- Automated Error Tracking. Collect detailed core dumps and backtraces automatically whenever a device crashes so you can fix bugs faster.
- Over-the-Air Updates. Deliver firmware updates securely to your devices with built-in support for staged rollouts and monitoring.
- Device Performance Metrics. Monitor critical health indicators like battery discharge rates, heap usage, and signal strength across your fleet.
- Remote Debugging. Access full system state and logs from remote devices without needing physical access or serial cables.
- Fleet Analytics. Visualize software version distribution and hardware health trends to identify problematic batches or firmware releases.
- Alerting and Notifications. Set up custom triggers to get notified the moment a specific error threshold is reached in production.
