Features

Minimal Setup

Just include the Errsole package in your code—no need for dedicated servers, software installations, or complicated configurations.

Errsole automatically collects all logs from the Node.js console. Additionally, it provides a custom logger with multiple log levels and allows you to include metadata with your logs for better context. Read More

Store Anywhere

Store your logs wherever you want—whether in a file or any database of your choice. You can also configure log rotation to specify how long logs should be retained.

Web Dashboard

View, filter, and search through your logs using the built-in Web Dashboard. Secure authentication and team management features ensure that only you and your team can access the logs.

Critical Error Notifications

Get immediate notifications when your app crashes or encounters critical errors. The notification includes the error message, the app name, the environment, the server name, and a direct link to view the error in your logs.

Benchmarks

A Node.js app using Errsole Logger can handle 90,000 more requests per minute than when using Elasticsearch and 70,000 more requests per minute than when using Amazon CloudWatch. Read More
