The database manager
that isn't an Electron app.
A native, open-source SQL client for Postgres, MySQL, SQLite, CockroachDB and Supabase. Built in Rust. An 11 MB installer — not a 250 MB Java IDE, not a 200 MB Chromium bundle pretending to be an app.

The other 689 megabytes
weren't doing anything.
Same six engines, same SSH tunneling, same visual EXPLAIN viewer. Minus the 250 MB Chromium runtime everyone else ships. The bars below are real installer sizes — drawn at a constant 180 MB/s, so the chart unfolds in roughly the time the downloads would actually take.
Sizes verified against each project's public installer pages. The cyan bar is the entire QueryDen app — drivers, vault, SSH, EXPLAIN viewer, AI assistant. See the full comparison →
Everything is a keystroke.
The 11 MB isn't a stripped-down toy. It's six engines, a schema-aware editor, a plan-tree viewer, an AI optimizer, parallel multi-DB query, line-level history, a real SSH stack — all reachable from one palette and one editor. Try the palette below.
SELECT * FROM users u JOIN orders o ON
- id uuid
- email text
- created_at timestamptz
- id uuid
- email text
- + email_verified bool
- + verified_at timestamptz
- created_at timestamptz
| id | org | verified | |
|---|---|---|---|
| 1 | ••••••@••••••.dev | •••••• | true |
| 2 | •••@•••••.com | •••••• | true |
| 3 | ••••••••@•••.io | •••••••• | false |
Runs only the
statement you mean.
Parse-aware. Cursor decides what runs — not the file.
Every five seconds.
Forever.
Silent line-level snapshots of every tab. Locally — never leaves your laptop.
One query.
Many databases.
Pick the engines, run once, get merged rows tagged with their source.
psql, but the right version.
Auto-downloads the matching server-version client. No "version mismatch" surprises.
And about 45 more — multi-cursor, schema search, transaction controls, query history, saved snippets, custom keymap presets, tab cycling, definition peek, EXPLAIN cost heatmap, signed updater, SSH tunneling, SQLite per-project files… all of them in the docs →
Credentials, locked to your hardware.
Every encrypted file is fingerprinted to the machine that wrote it. Copy your connections to another laptop and they're noise — by design. Read the threat model →
AES-256-GCM
Authenticated encryption for every connection, every saved query, every vault entry. Tampering invalidates the MAC; the file refuses to decrypt.
Argon2id KDF
Master password → key via a memory-hard KDF, making brute-force orders of magnitude slower than a GPU farm.
Machine fingerprint
Mixed into the KDF. Linux: /etc/machine-id. macOS: IOPlatformUUID. Windows: CSP UUID. Change machines, the vault refuses to load.
OS keychain
Master key in macOS Keychain (Secure Enclave-bound), Windows Credential Manager (DPAPI), or libsecret on Linux.
See the bytes of an encrypted vault.
The Security page walks the full file format — magic header, Argon2id salt, GCM nonce, ciphertext, MAC — annotated against the source. Plus the threat model: what we defend against, and what we don't.
