Native vs Electron: why it matters
Azure Data Studio is built on Electron (the same technology behind VS Code). While this makes it cross-platform, it comes at a cost. Electron apps bundle an entire Chromium browser engine, leading to slower startup times and higher memory consumption. On a MacBook with limited RAM and battery, this overhead adds up -- especially when running alongside a code editor, browser, and build tools.
SQLPro for MSSQL is built with Swift and Objective-C using native macOS frameworks. It launches instantly, uses minimal memory, and integrates with macOS features like iCloud Keychain, system notifications, and native keyboard shortcuts.
Where Azure Data Studio excels
Azure Data Studio offers Jupyter notebook integration for data analysis workflows, a VS Code-like extension marketplace, and built-in PostgreSQL support. If you work across both SQL Server and PostgreSQL, or if Jupyter notebooks are part of your workflow, Azure Data Studio has clear advantages.
SSH tunneling
SQLPro for MSSQL includes built-in SSH tunneling to connect to SQL Server instances behind firewalls. Azure Data Studio does not support SSH tunneling natively -- you need to set up an SSH tunnel externally before connecting.
The future of Azure Data Studio
Microsoft has confirmed that Azure Data Studio will be retired on September 30, 2025. After that date, the application will no longer receive updates, security patches, or support. Microsoft is directing users to Visual Studio Code with the MSSQL extension as the replacement. For macOS and iOS users who want a dedicated, native SQL Server client rather than a general-purpose code editor with a database plugin, SQLPro for MSSQL is an actively maintained alternative built for exactly this workflow.
Daily workflow comparison
For a typical day of query writing, data browsing, and stored procedure editing, SQLPro for MSSQL starts faster, uses less memory, and integrates with macOS features like iCloud Keychain for connection syncing. Azure Data Studio's strength is in its notebook-driven workflow for data analysis and its extension ecosystem for specialized tasks. If your work is primarily writing T-SQL and managing database objects, the leaner tool wins on efficiency.
Extension ecosystem
Azure Data Studio's extension marketplace offers tools for schema compare, SQL Server Admin Pack, PostgreSQL support, and community-built integrations. This makes it flexible for teams with diverse needs. However, extensions can introduce instability and increase memory usage. SQLPro for MSSQL takes the opposite approach -- everything you need for SQL Server is built in, with no plugins to manage or update.
Mobile access
Azure Data Studio is desktop-only. SQLPro for MSSQL also runs natively on iOS and iPadOS, allowing you to check query results, browse table data, or troubleshoot issues from your iPhone or iPad while away from your desk. Monthly and yearly subscriptions include all platforms at no extra cost.
macOS integration
As a native macOS app, SQLPro for MSSQL supports system features that Electron apps cannot fully replicate: native text rendering, system keyboard shortcuts, Spotlight integration, and proper Retina display scaling without the blurriness that some Electron apps exhibit. The app also respects macOS accessibility features like VoiceOver and Dynamic Type.
The verdict
If you value native performance, fast startup, and low resource usage on macOS, SQLPro for MSSQL is the better choice for day-to-day SQL Server work. If you need Jupyter notebooks, extensions, or PostgreSQL support alongside SQL Server, Azure Data Studio offers more breadth.
