What's next in 0.3.x: Tools, workspace roles, Schema Compare

These shipped in v0.3.4 — a Tools menu, per-browser workspace roles, Schema Compare, Settings Diff, and a What's new dialog.

August 19, 2026

These shipped in chmonitor v0.3.4. This post was the preview while they sat on main and dash.chmonitor.dev.

Tools menuSQL Console, Explorer, Explain, Advisor, Chart Builder, Schema Compare, Settings Diff — last group in Main.
Workspace rolesFull / DBA / Engineer / SRE. Hide and pin pages locally. The sidebar follows this browser.
Schema CompareTable DDL across hosts or replica nodes. Recommend-only plan — copy statements, never apply.
Settings Diffsystem.settings and merge_tree_settings, pair or matrix. All matched when nothing differs.

Tools, at the end of Main

Interactive work used to live under Queries, Tables, and Operations. It now lives in Tools — last group in Main, after Logs.

SQL Console, Data Explorer, Explain, Advisor, Chart Builder, Schema Compare, Settings Diff. AI Agent stays its own group. Postgres hosts do not see Tools (ClickHouse-family only).

The longer write-up is A DBA, an SRE, and an engineer should not share a sidebar.

Schema Compare and Settings Diff

DBA workflows is the map.

Schema Compare (/schema-diff) diffs CREATE TABLE across saved connections or replica nodes. One host is not enough — add a second, or compare nodes on this cluster. The plan is copy-only. Advisor findings can also emit a local statement plus an ON CLUSTER variant when topology is known.

Settings Diff (/settings-diff) diffs system.settings and system.merge_tree_settings. Filter to differences, or to values changed from default. When every setting matches: green check, All matched, then All to list them anyway.

What’s new, next to Settings

The newspaper icon next to the Settings gear opens What’s new — notes from docs/whats-new/ for each tagged version, newest first. It auto-opens once after an upgrade.
