DBDelve

A fast, native, cross-platform, multi-engine database client. Written in Rust with GPUI, no Electron and no JVM: instant startup, friendly on your memory, and smooth scrolling through large tables where other clients crash or introduce limits.

Early days. Everything listed below works today.

Scrolling a million rows:

Launching, with the last results already there:

Why

I wanted something which is performant, modern and consumes little ram. The existing DB clients are either filled with bloat (Electron and JVM) or paid. This is an alternative to them. No feature is ever going behind a paywall and with time we will have complete parity on features with those too.

Install

macOS (Apple Silicon, macOS 12 or later):

brew install --cask ShayanAbbas1/dbdelve/dbdelve
xattr -dr com.apple.quarantine /Applications/DBDelve.app

Don't skip the second line: the app isn't notarized, so macOS won't open it until the quarantine flag is cleared.

Linux (x86_64 or aarch64): yay -S dbdelve-bin from the AUR, or the tarball or AppImage from the latest release.

Windows (x86_64): unzip the zip from the latest release and run dbdelve.exe.

Updating, the .dmg, Linux requirements, building from source and where your data lives are all in docs/install.md.

Supported databases

Postgres, MySQL, MariaDB, SQLite, Turso, DuckDB, Snowflake, SQL Server, MongoDB, Redis (and Valkey, KeyDB, Dragonfly) and ClickHouse.

More engines are planned.

What it does

• Make it yours. The app's own themes alongside Catppuccin, Tokyo Night, Gruvbox and Dracula, each in dark, light and glass. Import themes from Zed or VS Code, or write your own.

• Bring your connections with you. Import every saved connection, passwords and SSH settings included, from DBeaver, or TablePlus on macOS.
• Organize your connections into projects, and jump to any of them from the palette.

• Never mistake prod for staging. Every connection is isolated and can color the title bar. Run it read-only, read-write or with full access, and DBDelve asks before anything destructive.

• Edits you can read first. Change a cell and DBDelve writes the UPDATE for you to check before it runs.
• Keep the columns you need. Hide or pin columns, and the layout survives a restart.
• Read a row in full in the row panel, with JSON highlighted, and edit long values there.

• Import rows from CSV, TSV or JSON, with every row checked and every statement shown before anything runs.

• Open a data file by dropping it on the window: a CSV, Excel, Parquet or JSON file opens in DuckDB, held in memory, as a query you can change. A .sql file opens in a new query tab on the connection you're on, and runs only when you run it.

• See the query plan highlighted in its own pane, with bad row estimates called out.

• Completion that knows your schema: tables, and a table's columns after its name and a dot.

• Keyboard-first. One palette for commands, tables, saved queries, history and connections, and every shortcut rebindable.

• Your SSH, not a reimplementation. Tunnels run through your own ssh, so your config, agent and hardware keys just work.

Free and open source, nothing behind a paywall, and no telemetry: the only request DBDelve makes on its own is an update check, which you can turn off.

Benchmarks

DBDelve 0.3.6 against DBeaver 25.3.1 on the same Postgres table, median of 5 runs each (2026-10-11, M1 Pro, 32 GB):

* The whole 1M-row table pulled into memory on purpose, with the row limit off. Method and full results in BENCHMARKS.md.
