Varan is a desktop SQL client for querying across different databases at once. Point it at MySQL, PostgreSQL, DuckDB, or spreadsheet files (CSV and Excel) and run a single SQL query โ including JOINs โ across all of them, without ETL pipelines or importing everything into one database first.
It runs on a local-first DuckDB engine, so queries execute on your own machine with read-only access to your sources: no admin rights, no server to set up, and nothing is written back to your databases.
Beyond cross-source SQL, Varan adds the tools data people always wish they had โ automatic anomaly detection when you open a table (duplicate keys, missing values, outliers, and orphaned foreign-key references), column-level lineage, git-style rollback of every change, and a Python surface on the same live tables you query in SQL.
Varan is a cross-platform desktop app for macOS, Windows, and Linux, currently in beta.
Key features in DbVisualizer include :
DbVisualizer connects to many popular databases through JDBC drivers, including MySQL, PostgreSQL, SQL Server, Oracle, Snowflake, SQLite, Cassandra, and BigQuery. It runs on Windows, macOS, and Linux.
With nearly 7 million downloads and Pro users in 150 countries, DbVisualizer scales from solo projects to enterprise-grade database management.
Varan DbVisualizerDbVisualizer is recommended for database administrators, developers, and data analysts who work with multiple database systems and require a reliable, versatile tool for database management, performance optimization, and data analysis. It's especially useful for those who appreciate a unified, cross-platform solution with strong visualization capabilities.
Varan's answer
Varan runs a single SQL query across different databases and files at once. Most SQL clients (DBeaver, DataGrip, TablePlus) connect to one database at a time; Varan lets you JOIN a MySQL table to a PostgreSQL table to a CSV in one statement, powered by a local-first DuckDB engine โ no ETL, no pipelines, no data copied into a warehouse first. On top of that it adds automatic anomaly detection, column-level lineage, and git-style rollback in the same workspace.
Varan's answer
Data analysts, analytics engineers, and data-adjacent developers who regularly work across several databases and spreadsheets. People who can write SQL but aren't DBAs โ they have read-only access to production and don't want to spin up ETL pipelines or a warehouse just to answer an ad-hoc question spanning two systems.
Varan's answer
Traditional SQL clients are single-database, so cross-source work means exporting and stitching data by hand. Federated engines like Trino or ClickHouse can query across sources but need infrastructure to stand up and manage. Varan sits in between: open a desktop app, point it at your sources (read-only, no admin), and query across all of them instantly โ with lineage, anomaly detection, and rollback built in. It's the convenience and workflow of a polished app on top of a serious engine, without the setup.
Varan's answer
Varan started from a recurring frustration: whenever an answer needed data from two places โ a Postgres database, a MySQL host, and the inevitable sales_final.xlsx โ the options were to build an ETL pipeline, hand-write fragile pandas glue, or give up. We wanted to just point one tool at everything and write a normal JOIN. So we built Varan around a local-first DuckDB engine that queries across sources directly, and added the data-quality and versioning tools we always wished we had. It's currently in beta.
Varan's answer
DuckDB (the local-first query engine) Electron + React (desktop application) Node.js (application/runtime layer) Python (bundled analysis surface) Java / Spring Boot (the licensing & sync hub backend) PostgreSQL (hub data store)
simple to use, versatile and increases productivity
I use DbVisualize since 2004... My personal idea is that DBVisualize is the best tool to develop complex SQL query, trigger, stored procedure...dbvis has a very simple export function to convert a query result in various format (csv, xlsx, JSON, SQL) In addition, dbvis has a very simple function to import flat data file into a table, or to generate DDL of entire database. another great functionality is a graphical editor to create a complex joins between two or more tables. Without dbvis my work be impossible!!!
