Postbird is an Electron-based PostgreSQL GUI for connecting to databases and inspecting table data and structure. The project publishes installers for macOS, Linux, and Windows and can also be run from source with Yarn. Its public download information centers on version 0.8.4, so users should confirm that the available build and database features match their current environment before relying on it.

pgpad is a work-in-progress cross-platform database client focused on quick startup, a small footprint, and routine SQL queries. It currently supports PostgreSQL and SQLite, with CockroachDB available through the PostgreSQL wire protocol. The project is intended for users who want a straightforward query tool rather than a full database-management suite such as DBeaver. Current documentation centers on building from source and requires npm plus Rust 1.85 or newer.

Outerbase Studio is a lightweight browser interface for managing SQL databases. It supports SQLite and related services such as LibSQL, Cloudflare D1, and rqlite, with query, data, schema, and connection-management tools. MySQL and PostgreSQL support is currently beta with limited features. A Windows and macOS desktop wrapper is available when a database driver cannot run in the browser.

Attu provides web and desktop workspaces for switching among Milvus clusters, browsing collections, importing or exporting data, running vector searches, and tracking backup, restore, copy, and other long-running tasks. Its optional AI agent can query data and perform approved administrative actions through natural language. The current v3 release is still distributed as a beta and supports Zilliz Cloud or open-source Milvus 3.x, not Milvus 2.6 or earlier 2.x versions.
