v0.3 · Coming soon to Microsoft Store

A SQL client
that remembers forgets.

SQL Studio is a Windows desktop client for Microsoft SQL Server. It does not save your passwords. It does not save your hostnames. Close the app and everything is gone. By design.

The difference

Your credentials never sleep on disk.

Most SQL clients save your connections so you don't have to retype them. That's convenient — and it's a file sitting on your machine waiting to leak. We made the opposite choice.

$ closing the app...

Everything is forgotten.

When you close SQL Studio, your passwords, hostnames, and usernames vanish with the process. There is no file to find, no Credential Manager entry to read, no recovery option. You re-enter what you need next time.

No disk persistence
Connections live in memory only. Nothing is written to disk.
No telemetry
No analytics, no crash reports, no third-party SDKs.
No accounts
No sign-in. No email. We do not know who our users are.
No middleman
Direct device-to-database. We don't operate any servers.
What's inside

Built for people who actually write SQL.

A focused subset of what SSMS does — the parts you reach for every day, refined.

Monaco editor

The same editor that powers VS Code. T-SQL syntax highlighting, multi-tab editing, dark theme tuned for long sessions.

Object Explorer

Browse databases, tables, views, stored procedures, and functions. Double-click to script SELECT or load definitions.

Query & cancel

Ctrl+Enter to run, button to cancel mid-query. Multiple result sets, typed columns, PRINT messages preserved.

Multi-tab workspace

Run different queries against different databases on the same connection without switching contexts.

Fast & native

Native Windows app, not a browser tab. Starts in under a second on a modern machine.

No bloat

~25 MB download. No background services. No update servers phoning home.

FAQ

Honest answers.

Why doesn't it remember my connections?

Because every saved-credentials file is a target — for malware, for backup leaks, for whoever picks up your laptop. Most clients encrypt these files, which raises the bar but doesn't eliminate the risk. We chose to skip the file entirely. Yes, it means re-typing your password each session. That's the trade.

Can I use it offline / on an air-gapped network?

Yes. The app makes no outbound network calls except to the SQL Server you specify. It never checks for updates, never phones home, and works perfectly on isolated networks where your DB lives.

Is this open source?

Not yet. We're focused on getting the first version stable on the Microsoft Store. Open-sourcing parts of it is on the table for v0.5+.

Does it support PostgreSQL / MySQL / SQLite / MariaDB?

No — only Microsoft SQL Server (and Azure SQL). Adding other databases is possible but would dilute focus. There are good clients for those already; we'd rather do one thing well.

Will it always be free?

The current v0.x is free during beta. After v1.0 we'll likely introduce a paid tier with optional power features (query history sync, advanced execution plans). The privacy-first core will remain free.

Is it on Mac / Linux?

Windows only for now. The underlying SQL Server driver works best on Windows, and we'd rather ship one excellent platform than three mediocre ones.

Why not just use SSMS?

If SSMS works for you, use SSMS. SQL Studio is for people who want a smaller, faster, less invasive tool — and who want to know that closing the app actually closes the book on their session.

Try it without trusting us.

Install once. Type your credentials when you connect. Close the app and they're gone. That's the whole pitch.
