Nembrix
A fast, open-source database client. Postgres-first, multi-session, SSH-first, scriptable, native-feeling.
Why another database client?
Section titled “Why another database client?”Nembrix is built for engineers who keep three connections open while shipping a migration. It treats sessions, schemas, and tabs as first-class state, and gets out of the way once you’re actually editing rows — free, open source, native, and Postgres-first.
Multi-session rail
Multiple live sessions per saved connection, drag-to-reorder, recent connections in one click.
SSH first
Native russh tunnels with password / key / agent auth and TOFU host verification.
Editable grid
Double-click a cell, edit, ⌘S commits every pending change in one transaction. Right-click for copy / set NULL.
JavaScript scripting
Write JS with await db.query(…), loops, and console.log over a live SQL connection — sandboxed, with a timeout & cancel.
Real EXPLAIN ANALYZE
Heat-colored plan tree, per-node cost or actual time, hot branches surface instantly.
Schema tools
Structure pane, schema diff with a migration preview, ER diagram, and a role / grant matrix.
Copy between connections
Move a table — or a whole database — from one live connection to another with FK ordering handled for you.
Private by default
Cross-platform (macOS / Windows / Linux). No required cloud account, no telemetry, no daemon.
