Log File Analysis should be Easy, Secure and Free

That’s why we made our Log Analyzer Open-Source! It has been designed for SEOs and we want the SEO community to take advantage of such technology.

We decided to fork the ELK (Elastic Search, Logstache, Kibana) stack and to make it easy to install with docker.

So you can use the open-source version and start doing log analysis for free — except your own hosting costs — and build your very own SEO dashboard.
