Overview
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.
Sentry
Sentry helps you see exactly what is broken in your code and why it is happening. Instead of digging through messy logs, you get real-time alerts that pinpoint the specific line of code causing an error, the users affected, and the environmental context. This allows you to fix bugs in minutes rather than hours, ensuring your application remains stable and your users stay happy.
You can also monitor your application's performance to find slow database queries or sluggish API calls that frustrate your customers. It supports over 100 languages and frameworks, making it a versatile choice whether you are building a mobile app, a website, or backend services. The platform scales with you, offering a robust free tier for individual developers and comprehensive plans for growing engineering teams.

- 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.
Sentry Features
- Error Tracking. Automatically capture unhandled exceptions and see the exact line of code, stack trace, and local variables that caused the crash.
- Performance Monitoring. Track transaction response times and identify slow API calls or database queries that are dragging down your user experience.
- Session Replay. Watch a video-like reproduction of exactly what your users saw and did leading up to a specific error or performance issue.
- Release Health. Monitor the success of your latest deployments in real-time and automatically trigger rollbacks if your new code introduces critical bugs.
- Issue Grouping. Reduce noise by automatically grouping similar errors into a single issue so you can focus on the problems that matter most.
- Custom Queries. Build your own dashboards and run complex queries across your event data to uncover trends and patterns in application behavior.
