Real-time PostgreSQL monitoring in your terminal.

A k9s-style terminal UI for observing and acting on live database activity. Not a database client — a tool for watching what your Postgres is actually doing, and stepping in when it misbehaves.

What is Tusk?

Tusk connects to a live PostgreSQL instance and gives you auto-refreshing views of what's happening right now — queries, transactions, sessions, locks, tables, and indexes. On top of that, a CEL-based rules engine lets you define policies that evaluate against live state and can automatically terminate, cancel, or log offending activity.

Tusk queries view showing live query activity — Live queries view with 2s auto-refresh.

Highlights

01Live views

Queries, transactions, sessions, locks, tables, and indexes — all refreshing every 2 seconds.

02Rules engine

Define policy rules in YAML using CEL expressions evaluated against live database state.

03Auto remediation

Automatically terminate, cancel, or log on rule violations — with dry-run and read-only safety.

04Violation tracking

Audit log of violations with a timestamped lifecycle: detected → action → cooldown → closed.

05Split-pane detail

Formatted SQL, transaction query history, and lock blocker/blocked shown side-by-side.

06Fast navigation

Tab through views, sort any column with Shift+letter, and filter instantly with /.
