QoreDB

QoreDB is a modern, open‑source database client written in Rust and packaged with Tauri, offering a single native interface for nine different database systems, including PostgreSQL, MySQL/MariaDB, SQL Server, SQLite, DuckDB, MongoDB, Redis and CockroachDB. It runs locally on macOS, Windows and Linux, keeping all data and credentials on the user’s machine; credentials are encrypted with Argon2 and no telemetry is sent.

The client provides an intelligent SQL editor with syntax highlighting, snippets, formatting and multi‑statement execution, as well as a performant data grid that supports virtual scrolling, server‑side filtering and inline editing. Features such as SSH tunneling, environment protection that blocks mutations in production, and a universal query safety net that detects dangerous statements aim to secure typical development workflows.

Additional tools include an interactive ER diagram for visual schema navigation, a sandbox with diff view for local data edits that generate clean SQL scripts, cross‑database federation for SQL joins across active connections, and an optional AI assistant that can generate, explain or correct queries using user‑provided API keys. The binary is lightweight (≈15 MB) and starts in under a second.
