For frontend monitoring and observability, I recommend using a mix of tools that cover performance monitoring, error tracking, logging, and user behavior analytics. Here are some of the best options:
1. Performance Monitoring
- Google Lighthouse – Audits performance, accessibility, SEO, and best practices.
- Web Vitals – Measures core web vitals like LCP, FID, and CLS.
- Calibre – Monitors site speed and user experience over time.
- SpeedCurve – Tracks real user experience (RUM) and performance trends.
2. Error Tracking & Logging
- Sentry – Monitors frontend and backend errors with deep stack traces.
- LogRocket – Records user sessions and logs errors for debugging.
- New Relic Browser – Tracks errors and performance issues in real-time.
- Datadog RUM – Monitors real user behavior and frontend issues.
3. User Session Replay & Analytics
- Hotjar – Provides heatmaps, session recordings, and feedback tools.
- FullStory – Tracks user interactions and helps diagnose UI/UX issues.
- Mouseflow – Tracks user journeys, heatmaps, and conversion funnels.
4. Logging & Observability
- Elastic Stack (ELK) – Log aggregation and analytics using Elasticsearch, Logstash, and Kibana.
- Grafana Loki – Lightweight log aggregation optimized for Kubernetes and cloud apps.
- Fluentd – Open-source log collector.
5. API & Network Monitoring
- Postman Monitors – Tracks API uptime and response times.
- AWS CloudWatch – Monitors cloud services and logs.
- Pingdom – Uptime and performance monitoring.
6. OpenTelemetry for Frontend Tracing
- OpenTelemetry JS – Open-source telemetry framework for traces, metrics, and logs.
- Jaeger – Distributed tracing for microservices.
