Overview:
highlight.io is an open-source, fullstack monitoring platform designed for developers. It integrates session replay, error monitoring, and logging into a single, cohesive tool. Instead of juggling multiple legacy monitoring solutions, developers can use highlight.io to understand both user-facing issues and server-side problems from one interface. The platform supports self-hosting and is built with modern development workflows in mind.
Core Features:
Session Replay: Record and replay user sessions to see exactly what happened before an error, including console logs, network requests, and user interactions.
Error Monitoring: Automatically capture errors with customizable grouping and alerting rules. Each error links directly to associated session replays for full context.
Logging & Log Alerts: Collect and search across all server logs with automatic property extraction. Set thresholds for log alerts and view them in a centralized dashboard.
Traces: Track the performance of server operations with powerful search and automatic property collection. Each trace links to related sessions, errors, and logs.
Session Comments: Leave comments on specific errors or sessions to communicate with your team about bugs or user frustration.
Use Cases:
Developers debugging frontend issues: Replay user sessions to see exactly what a user did leading up to an error, with full console and network context.
Development teams monitoring errors: Group and alert on recurring errors across frontend and backend, with customizable rules for where alerts are sent.
Engineers analyzing server performance: Search and filter traces to understand slow operations, linked to the relevant logs, errors, and user sessions.
Self-hosters deploying a monitoring stack: Deploy a hobby instance on Linux with Docker using a single command, requiring at least 8GB of RAM, 4 CPUs, and 64 GB of disk space.
Why It Matters:
highlight.io offers an all-in-one monitoring stack (session replay, error monitoring, logging, and traces) that works out of the box, reducing the need to stitch together separate tools like Grafana, Loki, or the ELK stack. Its open-source nature allows developers to self-host, and the platform is designed around a cohesive experience where each feature—sessions, errors, logs, and traces—links to the others for faster debugging.
