chmonitor vs Papercrane

chmonitor reads ClickHouse system tables to show queries, merges, replication and disk health in one place, with alerting and a read only AI advisor.

Every analytics vendor is bolting an AI copilot onto their dashboards. Power BI has one. Tableau has one.

About chmonitor

chmonitor is an open source operations dashboard for teams running ClickHouse. It builds its views directly from ClickHouse system tables, so no exporters or extra storage are required. Engineers can inspect running, failed, slow and costly queries, run EXPLAIN, and stop long queries from the table. A topology map shows nodes, shards and replicas plus the Keeper quorum with metrics for each node, while health checks notify Slack, Discord, PagerDuty or Opsgenie when thresholds are crossed. A built in agent studies schema and query history to suggest tuning, and it can be reached over MCP in read only mode. Self hosting is free, and a CLI is in beta.

About Papercrane

Every analytics vendor is bolting an AI copilot onto their dashboards. Power BI has one. Tableau has one. They all work the same way: the human drives the old tool, and the AI sits in a sidebar making suggestions. I took the agent you already use and built the BI tool around it. papercrane-cli is a command line tool that gives Claude Code everything it needs to turn a business question into a live dashboard: authenticated access to your data, a real dashboard workspace, and a path to a link you can send to anyone.
