![Cove demo](docs/hero.gif)

### Supported databases

  

    
PostgreSQL

    
MySQL

    
MariaDB

    
SQLite

    
MongoDB

    
Redis

    
ScyllaDB

  

  

    
Cassandra

Adding a new backend requires zero changes to UI code — see [`DB/README.md`](Cove/DB/README.md).

## Features

- **Browse** schemas, tables, views, indexes, and keys in a sidebar tree

- **Edit rows** inline with SQL/CQL preview before commit

- **Run queries** with syntax highlighting and autocomplete

- **Multiple tabs** with independent connections (Cmd+T)

- **Connection environments** — local, dev, staging, production

- **SSH tunneling** — password or private key authentication

- **SQLite over SSH** — browse and query a VPS-hosted SQLite file from the same SQLite connection flow

- **Session persistence** — connections and tabs restore across app relaunches

- **Color-coded indicators** and connection tooltips

- Native macOS UI — no Electron, no web views

## Install

Download the latest `.dmg` from [Releases](https://github.com/emanuele-em/cove/releases/latest).

> On first launch, macOS may block the app. Right-click the app and select **Open** to bypass Gatekeeper.

Or build from source:

```bash

# One-time Xcode setup, if needed

xcodebuild -runFirstLaunch

xcodebuild -scheme Cove -derivedDataPath .build build

open .build/Build/Products/Debug/Cove.app

```

If `xcodebuild` fails because Xcode has not completed setup on your machine, run `xcodebuild -runFirstLaunch` once and retry.

Requires macOS 15+.

## Roadmap
