Grafito is a self-hosted web application for examining events recorded by the systemd journal. It presents diagnostic information in a browser-based interface with live updates, flexible filtering and graphical representations of system activity.
The application has evolved beyond a simple journal viewer. Its dashboard includes an event frequency chart, a severity minimap and an inspector panel for examining individual entries together with their surrounding context.
Users can narrow the displayed information by service unit, tag, hostname, priority, time range and search terms. Server-Sent Events provide live updates, with polling available as a fallback.
Grafito also offers optional AI-powered explanations of messages. When configured with a supported provider, it can explain errors and answer follow-up questions. This functionality is not required for normal operation.
The project additionally offers features for administering self-hosted services, including Docker-related tools and optional Model Context Protocol integration.
This is free and open source software.

I love Linux Links, but I do not understand how Grafito is included in today’s RSS feed as a worthy journalctl GUI tool but it is not listed among the top 16 log reviewers. Is that because it is too new?

The answer is simple. We have finite resources. Before a roundup is updated, we need to evaluate the software. This takes time.
And just because a program appears in our feed doesn’t itself mean it’ll even get added to a roundup.
