A web log viewer and logging framework for Rack applications

Live Demo



Add these lines to your application's Gemfile:

gem 'redis'
gem 'logster'

And then execute:

$ bundle

Logster will wire up /logs path in your Rails app in development mode only. Production mode is being worked on.


Logster is in current development, at the moment the focus is on a decent tool for dev. Once that is complete production mode will be built.

The concept is to have an embedded "exception reporting service" admins can view on live sites.

Logs will be visible by default at http://sitename.com/logs, only dev mode is implemented now.


Logster UI is built using Ember.js
