The free bar inventory program that beats what most places pay for.
Open Source Barware is bar inventory software you download once and run on your own machines — bottle maps, pour cost, variance, and weekly counts without a monthly invoice.
Spreadsheets, SaaS, or open source. Pick the workflow that respects your margin.
| Approach | Cost | Setup | Variance | Data ownership |
|---|---|---|---|---|
| Spreadsheets | Free (your labor) | Manual formulas, no bottle map | End-of-month guesswork | File chaos, version drift |
| Paid bar SaaS | $50–$300+/mo per location | Vendor onboarding, seat limits | Often strong, behind a paywall | Subscription + export friction |
| Open Source Barware | Free — GPLv3, no seats | Walk your bar, voice or keyboard | Bottle, category, or shift level | Your data stays yours |
Built for a working bar, not a slide deck.
Location-mapped inventory
Wells, back bar, liquor room, and storage bins — counted where bottles actually live, not dumped into one sheet tab.
Pour cost and variance
See where liquor cost leaked before month-end close. Category and bottle-level views for managers who run tight numbers.
Voice walk-through setup
Dictate stations while you walk the room on the first night. Built for a real shift, not a conference demo.
Invoice and POS inputs
Upload delivery invoices and tie receiving to counts. Reconcile what came in against what should be on the shelf.
500+ product starter database
Common brands, bottle sizes, and pours pre-loaded so you are not building a SKU list from scratch at midnight.
Open source forever
Source code published. No black-box cloud lock-in. Fork it, audit it, run it on your own machines.
Questions operators ask before they download.
Is Open Source Barware really free bar inventory software?
Yes. The program is free to download and use under GPLv3. There is no subscription, no per-seat fee, and no trial that expires.
How does free bar inventory software compare to paid systems?
Paid systems often charge monthly per location and gate exports or advanced variance behind tiers. Open Source Barware ships the full count, map, variance, and reconciliation workflow without a paywall — because it was built for working bars, not recurring billing.
Do I need to sign up or create an account?
No account is required to download. Optional email signup on the download page is only for release updates and Hidden Bar Tour invites — both are opt-in.
Who built this?
Bartenders and operators. Open Source Barware is a Richard B. Jamison project under Intelligent Hospitality Systems.
Does it work for liquor and wine only?
It tracks the full bar — liquor, wine, beer, modifiers, and in-house prep. See our liquor and wine inventory pages for category-specific workflows.
