chmonitor vs Qursor

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

Qursor is a Chrome extension that captures selectors, classes, styles and notes for a chosen page element so coding assistants can make targeted interface fixes.

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 Qursor

Qursor is a Chrome extension built for developers who use AI coding assistants on front end work. Rather than sending screenshots, the user hovers over an element on a production, staging or localhost page, inspects its typography, colours and spacing, and either edits styles directly or leaves an annotation. Qursor then copies the selectors, classes, edits and notes as structured text the agent can act on, which the maker says saves tokens and avoids searching an entire codebase. It can also lift components from live sites as HTML, CSS or JSX, and includes a colour picker with a palette view. A free starting option exists, while paid pricing is not shown on the homepage.
