nerdlog vs grafana
Log investigation and observability platforms compared
nerdlog searches logs across SSH-accessible hosts in a terminal, while grafana provides dashboards and exploration across observability data sources. nerdlog focuses on remote log queries without a central server; grafana covers metrics, logs, traces, visualization, and alerting.
nerdlog: Search Logs Across Remote Hosts in a Terminal
Nerdlog is a Go terminal app for querying logs across SSH-accessible hosts without a central server. It combines filtered log results with a timeline histogram, making it useful for operators who need a lightweight alternative to centralized log platforms.
grafana: Explore and Visualize Observability Data
Grafana is a platform for querying, visualizing, and alerting on metrics, logs, and traces across data sources. It suits teams that need shared dashboards and a common way to explore operational data.

Key differences
- nerdlog is a terminal log viewer for multiple remote hosts; grafana is a platform for exploring and visualizing data from multiple sources.
- nerdlog analyzes logs on SSH-accessible hosts and brings matching results together; grafana combines data through configured sources and dashboards.
- nerdlog searches log files or journalctl output with time ranges and awk-pattern filters; grafana supports ad-hoc queries, drilldowns, and comparisons across metrics and logs.
- nerdlog is written in Go and licensed under BSD-2-Clause; grafana is written in TypeScript and licensed under AGPL-3.0-only with Apache-2.0 exceptions described in its licensing document.
- nerdlog is aimed at operators investigating logs across a small or distributed fleet without a central logging server; grafana targets teams needing shared dashboards, exploration, and alerts.
Choose nerdlog if you…
- need to investigate logs across SSH-accessible hosts without setting up a central logging server.
- want to filter remote logs by time and compare results in a terminal timeline.
- work with Linux-style system logs and can meet nerdlog's remote-host requirements, including GNU awk.
Choose grafana if you…
- need shared dashboards to visualize observability data from configured sources.
- want to explore metrics and logs, compare time ranges, and follow label filters across data.
- need alert rules and notifications alongside dashboards and queries.
