Jam SQL Studio Jam SQL Studio Pricing
Jam SQL Studio is free forever for personal, non-commercial use — unlimited connections, IntelliSense, execution plans, schema compare, data compare, and every core workflow, with generous size caps on a handful of bulk operations. Pro removes those caps and adds a commercial-use license for $9.99/month or $99/year (save 17%). Personal needs no account at all; sign in inside the app to start a 14-day Pro trial — no card required.

- Saved sessions and AI context. Multiple named sessions you can switch between and resume, 100 closed tabs of history instead of 5, and AI Workspace sync — schema export, file sync and context files for your AI agent.
Personal is free forever without an account. Sign in inside the app, then start the 14-day Pro trial yourself — no card required.

Trials & Licensing
- Pro includes a 14-day free trial — no card required. It is tied to your account, so download the app, sign in, and start the trial from the prompt the app shows you or from Settings → Account. Each account gets one trial — extendable once by 14 more days if you answer the app's one-question feedback prompt when it expires — and a machine that has just run someone else's trial waits 7 days before it can start another.
- To buy Pro, open Settings → Account → Subscribe to Pro in the app. That opens a Stripe checkout in your browser and the app switches to Pro once the payment is confirmed — this website has no purchase page.
- A Pro license is per-user; use it on as many machines as you personally use.
- Subscriptions can be cancelled any time and will not renew; the current paid period is not refunded. See the EULA for full terms.
- All prices are in USD. Local currency conversion and applicable VAT/sales tax are calculated at checkout by the payment processor.
- Enterprise plans (volume licensing + invoicing) — contact [email protected].
Frequently Asked Questions
Common questions about Jam SQL Studio pricing, caps, and licensing.
How much does Jam SQL Studio cost?
Jam SQL Studio is free forever for personal, non-commercial use. Pro costs $9.99 per month or $99 per year (a 17% saving) and adds a commercial-use license plus higher limits on a few bulk operations.
Is Jam SQL Studio free?
Yes. The Personal tier is free forever for individual, non-commercial use: unlimited connections across six database engines, the full Query Editor with IntelliSense, Table Explorer, charts, execution plans, PL/SQL debugger, SQL notebooks, and a local MCP server. A handful of bulk operations carry generous size caps, Schema Overview auto-loads large schemas up to 100 objects (still opens, just truncated), and closed-tab history keeps your last 5 tabs (Pro keeps 100) — everything else is unlimited.
What exactly is capped on the free Personal tier?
Eight operations carry a cap: Schema Compare (200 objects per schema), Database Blueprint (200 objects), Data Compare (10,000 rows per table; sampled compares are unlimited), exporting results (100,000 rows), importing a file (100,000 rows), cloning a database with data (1 GB), cloning a table with data (100,000 rows), and creating a backup (1 GB source database). Restoring a backup has no size limit on either tier.
Is Backup & Restore limited to 1 GB?
Only creating a backup is capped at 1 GB on the free Personal tier. Restoring a backup, of any size, has no limit on Personal or Pro.
Is query history a Pro-only feature?
No. Query history with full-text search is available on every tier. The only difference is closed-tab history: Personal keeps your last 5 closed query tabs, Pro extends that to your last 100 closed tabs.
What do I get with Pro?
Pro removes the Personal-tier size caps (unlimited Schema Compare, Database Blueprint, Data Compare, export, import, clone, and backup), adds a commercial-use license, AI Workspace sync, multiple named sessions, 100 closed-tab history, and Schema Overview extras: impact analysis, annotations, advanced layouts, diagram comparison, and SVG/PDF/DOT export.
Is there a free trial for Pro?
Yes, and no credit card is required. The trial is tied to an account, so the sequence is: download the app, sign in, then start the trial from the prompt the app shows you or from Settings → Account. Each account gets one 14-day trial, and when it expires you can extend it once by 14 more days by answering the app's one-question feedback prompt.
Can I use the free Personal tier for commercial work?
No. The Personal tier is licensed for personal, non-commercial use only. Pro adds the commercial-use license needed for work use.
How do I upgrade to Pro?
Upgrade inside the app: open Settings → Account and choose Subscribe to Pro. That opens a Stripe checkout in your browser, and the app switches to Pro as soon as the payment is confirmed. The website has no purchase page — jamsql.com only hosts the download.
