Jam SQL Studio Best SQL Client for Windows in 2026
On Windows the starting point is SSMS: it's free and it's still the deepest SQL Server administration tool. The question is what you need that SSMS doesn't give you — another database engine, a machine SSMS 22 won't install on, charts and notebooks, or AI agents that can query your databases. This page compares six Windows SQL clients on those points, with versions, download sizes and prices checked on September 26, 2026.
The Short Answer: Which Windows SQL Client to Pick
- SQL Server administration on Windows 11: SSMS 22. Free, Microsoft's own tool, and the place for maintenance plans, the SSIS catalog and the XEvent Profiler.
- Many database engines, free, open source: DBeaver Community. Broad JDBC coverage; SQL Server execution plans, charts and schema/data compare are in the paid PRO editions.
- You already use JetBrains IDEs: DataGrip. Free for non-commercial use, paid for work; the biggest download here at about 850 MB.
- Smallest install, MySQL and MariaDB first: HeidiSQL. Free and open source, an 18 MB installer or a portable ZIP.
- Several engines plus SQL Server DBA views, charts, notebooks and AI agents in one app: Jam SQL Studio. Free for personal, non-commercial use; Pro ($9.99/month or $99/year) for work. Installs per user without an admin prompt on Windows 10 and 11 (x64 only).
How we compared: versions, system requirements, download sizes and prices come from each vendor's own download page, release notes, documentation or price list, read on September 26, 2026. Jam SQL Studio facts come from its documentation and changelog. Where a vendor's documentation doesn't list a feature, the table says “not listed” rather than guessing.

The Six Tools, and Where Each Falls Short
1. SQL Server Management Studio (SSMS) 22
Microsoft's SQL Server tool: free, with a dark theme. SSMS 22.0 shipped on November 11, 2025; 22.10.2 followed on September 28, 2026. GitHub Copilot in SSMS became generally available in 22.4.1 (March 2026), and 22.7 (June 2026) added Copilot Agent Mode and Schema Compare in preview; both have been generally available since 22.10.2. Where it falls short: SQL Server only, Windows only, Windows 11 or Windows Server 2019+ only, an administrator install of 4–50 GB, and no charts or notebooks.
2. DBeaver Community 26.2
Free and open source, with installers for x64 and ARM64 Windows that bundle their own Java runtime, so there is nothing extra to install. It connects to most relational databases over JDBC. Where it falls short: DBeaver's documentation puts SQL Server execution plans, result charts, schema compare and data compare in the paid PRO editions (Lite from $113/year, Enterprise $255/year), and NoSQL databases in Ultimate.
3. DataGrip 2026.2
JetBrains' database IDE: strong SQL completion and refactoring, execution plans with a flame-graph view, schema compare with a migration script, result charts, and a built-in MCP server since 2025.2 that lets external AI agents run queries. It has been free for non-commercial use since October 2025, with anonymous usage statistics that can't be turned off on that license. Where it falls short: work use needs a paid subscription, and the Windows installer is about 850 MB.
4. HeidiSQL 12.21
A small, free, open-source client that has been a Windows staple for MySQL and MariaDB for years, and also connects to SQL Server, PostgreSQL, SQLite, Interbase and Firebird. The installer is 18 MB, and a portable ZIP runs without installing. Version 12.21 also ships Linux and macOS builds made with Lazarus and FreePascal. Where it falls short: no Oracle, and its documentation doesn't list execution plan diagrams, schema compare, charts or AI features.
5. TablePlus
A native app with a clean UI that connects to SQL Server, PostgreSQL, MySQL, Oracle, SQLite, Redis, MongoDB and more. Where it falls short: the free trial stops at 2 open tabs and 2 open windows, a Basic license is $99 per device including one year of updates, and its site lists no AI features.
6. Jam SQL Studio 1.5
One app for SQL Server, Azure SQL, PostgreSQL, MySQL, MariaDB, Oracle, SQLite and Azure Data Explorer, with execution plans on four engines, schema and data compare, charts, SQL notebooks and SQL dashboards. For SQL Server work it adds a Session Browser, Performance Dashboard, Query Store viewer, deadlock analyzer and an Agent Jobs manager (beta). Version 1.5.1 added editable keyboard shortcuts with an SSMS / Azure Data Studio scheme, and PRINT and low-severity RAISERROR output now appear in Messages. A local MCP server lets Claude Code, Cursor, Copilot and other agents query your databases under a per-connection permission level that starts at Block. Where it falls short: no maintenance plans, Extended Events profiler or SSIS; no native ARM64 Windows build; and the free Personal tier is for non-commercial use only — work use needs Pro, and a few bulk operations are capped on Personal (schema compare 200 objects, data compare 10,000 rows per table, export 100,000 rows).
When to Use Jam SQL Studio Instead of SSMS on Windows
SSMS is excellent at SQL Server administration. This is the honest split.
Use SSMS when
- You're administering SQL Server itself: maintenance plans, replication, Always On, the SSIS catalog, Database Engine Tuning Advisor.
- You need the Extended Events / XEvent Profiler UI.
- Your team's runbooks, screenshots and shortcut habits are all SSMS-based, and every machine runs Windows 11.
Use Jam SQL Studio when
- Your environment has more than one engine. SSMS only speaks SQL Server; Jam SQL Studio puts PostgreSQL, MySQL, MariaDB, Oracle, SQLite and Azure Data Explorer in the same window with the same shortcuts.
- SSMS 22 won't install: a Windows 10 machine, or a managed laptop where you can't get administrator rights.
- You want to keep SSMS keys. Pick the SSMS / Azure Data Studio scheme in Settings → Keyboard Shortcuts: F5 executes, Alt+Break cancels a query and Ctrl+R toggles the results pane. See shortcut schemes.
- You're moving off Azure Data Studio after its February 28, 2026 retirement and miss charts, SQL notebooks and a cross-platform app.
- You want AI agents (Claude Code, Cursor, GitHub Copilot, Codex CLI) to query your databases through a local MCP server with per-connection permission levels: Block by default, Read-only, or writes that ask for your approval.
- You want schema compare, data compare and execution plans in one tool, including on PostgreSQL, MySQL and Oracle.
Both tools can live on the same Windows machine. Keeping SSMS for server administration and using Jam SQL Studio for daily development is a common split.
Connecting to SQL Server from Windows in Jam SQL Studio
What works on a Windows machine, per the connections guide.
Windows Authentication
Connect with your signed-in Windows account — no password to type when your domain account already has SQL Server access. Windows Authentication is available when the app runs on Windows.
Named instances and local servers
Leave the port blank and the bundled SQL Tools Service chooses Shared Memory, Named Pipes or TCP, which reaches a local default instance on any port or a local named instance without the SQL Browser service.
Microsoft Entra ID
Azure SQL Database and Managed Instance connections sign in through your browser (MFA included) or with the device-code flow, with an optional tenant ID for guest accounts. The token cache is persisted between sessions.
Signed per-user installer
An Authenticode-signed NSIS installer, about 210 MB, that installs into your profile without an administrator prompt, supports /S for unattended installs, and updates itself in the background. There is no MSI or portable build.
Encrypted connections
Encrypt Connection turns on TLS for data in transit; Trust Server Certificate accepts a self-signed certificate for development servers.
More engines on the same machine
PostgreSQL with SSL modes and client certificates, MySQL/MariaDB, Oracle through the Thin driver (no Oracle Client install), SQLite files, and Azure Data Explorer — one Windows app instead of SSMS plus pgAdmin plus MySQL Workbench.
Replacing Azure Data Studio on Windows (Retired Feb 2026)
How the Azure Data Studio workflows map to the tools that are still maintained.
Microsoft retired Azure Data Studio on February 28, 2026. Its current guidance sends daily work to Visual Studio Code with the MSSQL extension and SQL Server Agent and full administration to SSMS. The MSSQL extension has caught up on a lot — execution plans, schema compare and SQL notebooks are all generally available — but it is still a SQL Server-only editor extension.
| Azure Data Studio workflow | SSMS 22 | VS Code + MSSQL | Jam SQL Studio |
|---|---|---|---|
| SQL notebooks (.ipynb) | ✗ | ✓ GA | ✓ |
| Charts from query results | ✗ | ✗ | ✓ |
| Schema compare | ✓ GA (22.10.2) | ✓ GA | ✓ |
| Execution plans | ✓ | ✓ GA | ✓ |
| SQL Server Agent jobs | ✓ | ✗ (Microsoft points to SSMS) | ✓ Beta |
| PostgreSQL / MySQL / Oracle | ✗ | PostgreSQL via a separate extension | ✓ Built in |
| Kusto (Azure Data Explorer) | ✗ | ✗ | ✓ |
Jam SQL Studio also reads Azure Data Studio's settings.json and imports your saved SQL Server, PostgreSQL and Kusto connections with their server groups. For step-by-step migration, see the Azure Data Studio migration guide. To compare the replacement options, see Azure Data Studio alternatives.
Frequently Asked Questions
Common questions about SQL clients for Windows.
What is the best SQL client for Windows in 2026?
It depends on the work. For SQL Server administration on Windows 11, SSMS 22 is free and still the most complete tool. For many database engines in one free app, pick DBeaver Community. For JetBrains users, DataGrip. For the smallest install and MySQL or MariaDB work, HeidiSQL. Jam SQL Studio fits developers who move between SQL Server, PostgreSQL, MySQL, Oracle and SQLite, want charts, notebooks and schema and data compare in one app, and want AI agents to reach their databases through a local MCP server.
Does SSMS run on Windows 10?
Not the current release. The system requirements for SSMS 22 (22.10.2 as of September 28, 2026) list 64-bit Windows 11, including Arm64 editions, and Windows Server 2019, 2022 and 2025. Windows 10 is not on that list, and installing SSMS 22 needs administrator rights. Jam SQL Studio supports Windows 10 and 11 (x64) and installs per user without an administrator prompt.
Is there a free SQL client for Windows?
Yes, several, under different licenses. SSMS and the VS Code MSSQL extension are free SQL Server tools from Microsoft. DBeaver Community and HeidiSQL are free and open source. DataGrip is free for non-commercial use only. Jam SQL Studio's Personal tier is free for personal, non-commercial use; work use needs Pro at $9.99 per month or $99 per year. TablePlus runs as a trial limited to 2 open tabs and 2 open windows until you buy a license. See the free SQL client comparison.
Which Windows SQL clients run natively on ARM64 laptops?
SSMS 22 added initial Arm64 support in version 22.0, and its system requirements list Windows 11 Arm64 editions. DBeaver Community and DataGrip both publish ARM64 Windows installers. Jam SQL Studio ships an x64 Windows build only; there is no native ARM64 Windows build.
Does Jam SQL Studio support Windows Authentication?
Yes. On Windows, SQL Server connections can use Windows Authentication with your signed-in Windows account, and leaving the port blank lets the bundled SQL Tools Service choose Shared Memory, Named Pipes or TCP, which also reaches a local named instance without the SQL Browser service. Azure SQL Database and Managed Instance connections can use Microsoft Entra ID through an interactive browser sign-in or the device-code flow.
When should I use SSMS instead of Jam SQL Studio on Windows?
Use SSMS for SQL Server work Jam SQL Studio does not cover: maintenance plans, Extended Events and Profiler sessions, replication and Always On setup, the SSIS catalog, and Database Engine Tuning Advisor. Use Jam SQL Studio for development across several engines, charts and SQL notebooks, schema and data compare, AI agents through a local MCP server, or on a machine where SSMS 22 will not install, such as Windows 10 or a laptop without administrator rights. Many teams keep both.
Download Jam SQL Studio for Windows
Free for personal, non-commercial use, with no account. Windows 10 and 11 (x64), per-user install without an admin prompt. Pro for work use: $9.99/month or $99/year, with a 14-day trial after you sign in inside the app.
