Finding the right SQL editor can make or break your database development experience. While commercial options exist, the open source community has created powerful, feature-rich SQL editors that rival their paid counterparts—without the licensing costs.

Whether you’re a database administrator, developer, or data analyst, having a reliable SQL editor with syntax highlighting, auto-completion, and robust query execution capabilities is essential for productive database work.

Let’s explore the best free and open source SQL editors available today. (And yes, we’ll start with our own tool—but we promise it’s actually good!)

Beekeeper Studio Community Edition

The interface is thoughtfully designed to minimize distractions while maximizing productivity—perfect for developers who want to focus on writing great SQL.

DBeaver Community Edition

Available for Windows, MacOS, and Linux

DBeaver Community Edition is a comprehensive open source SQL editor and database tool that supports virtually every database system imaginable. Its universal database connectivity makes it popular among developers who work with multiple database types.

The SQL editor in DBeaver includes syntax highlighting, auto-completion, and query execution planning. It also provides advanced features like visual query building, database structure browsing, and extensive data import/export capabilities.

While DBeaver offers impressive functionality, its interface can feel overwhelming for users who prefer a more streamlined experience. The abundance of features sometimes comes at the cost of simplicity and ease of use.

Visual Studio Code with SQL Extensions

Available for Windows, MacOS, and Linux

Visual Studio Code becomes a capable SQL editor when enhanced with database extensions. Popular extensions like “SQL Server (mssql)”, “SQLTools”, and “PostgreSQL” add comprehensive SQL editing capabilities to the beloved code editor.

VS Code’s SQL extensions provide syntax highlighting, IntelliSense auto-completion, query execution, and result visualization. The advantage is seamless integration with your existing development workflow—you can work with SQL alongside your application code in the same editor.

If you’re already invested in the VS Code ecosystem, adding SQL capabilities through extensions provides a familiar and integrated development experience without needing separate tools.

The SQL editor in HeidiSQL features syntax highlighting, auto-completion, and a tabbed interface for managing multiple queries. Results are displayed in an editable grid format that allows for quick data modifications and export to various formats.

One of HeidiSQL’s strengths is its portability—it can run without installation, making it convenient for developers who need database access across different machines. However, its Windows-only availability limits its usefulness for cross-platform teams.
