Nerdlog

Nerdlog is a fast, remote-first, multi-host TUI log viewer with timeline histogram and no central server. Loosely inspired by Graylog/Kibana, but without the bloat. Pretty much no setup needed, either.

It's laser-focused on being efficient while querying logs from multiple remote machines simultaneously, filtering them by time range and patterns, while also drawing a timeline histogram for quick visual insight.

Primary use case: reading system logs (/var/log/messages or /var/log/syslog) from one or more remote hosts. Very efficient even on large log files (like 1GB or more).

It does support some other log formats and can use any log files, but that was the primary use case which was driving the implementation: we were having our web service backend running as systemd services on a bunch of Linux instances, printing a lot of logs, and wanted to be able to read these logs efficiently and having the timeline histogram, much like tools like Graylog have.
