The database explorer that speaks every engine

One fast, native desktop app for SQL and NoSQL alike. Browse, query and edit Postgres, MySQL, SQL Server, SQLite, MongoDB, Redis and more — and extend it with plugins when you need something new.

Everything you need to work with data

A calm, native interface — not a browser tab pretending to be an app.

Multi-database

SQL and NoSQL side by side. Connect to relational engines, document stores and key-value databases from one tree.

Query editor

Syntax highlighting, multiple tabs, rebindable shortcuts, and open/save of .sql files with a dirty-marker.

Editable grid

Edit results in place and commit changes back to the database — no round-trip through hand-written UPDATE statements.

Import & export

CSV in and out, JSON and SQL export, and SQL Server BACPAC/DACPAC via the tool plugins. Move data where you need it.

Plugin system

Providers, tools, MCP servers and extensions load at runtime in isolation. Add an engine without touching the host.

AI-ready (MCP)

An opt-in MCP server lets AI assistants query safely — read-only per connection, on a loopback port, with an audit log you control.

Extensible by design

Four kinds of plugin, one clean SDK

Every plugin ships as a folder next to the app and loads into an isolated AssemblyLoadContext. Only the SDK and Avalonia are shared with the host — so a plugin can add a database, run a tool, bridge your data to AI, or stand up a whole subsystem without ever destabilising the app.

ProviderTeach SQL Explorer a new database engine.

ToolRun an operation — backup, export, migration.

MCPExpose data to AI assistants over MCP.

ExtensionStand up a standing subsystem — like local containers.
