Two bartenders who
got tired of counting
the same bottles every week.
If you’ve worked behind a bar, you know. The shift ends, the guests leave, and instead of going home you’re on your knees behind the well, holding a bottle of Tito’s up to the light trying to decide if that’s three-tenths or four.
You scribble numbers on a count sheet. You walk to the back office and type them into a spreadsheet that hasn’t been updated since someone else was bar manager. You try to match it all against the POS report. The numbers never line up.
Over the years, companies saw the pain and monetized it. Inventory guns for $3,000. Monthly software at $200 a location. Consultants who charge by the hour to do what you already know how to do — just with a shinier clipboard.
Then AI showed up. And suddenly, building genuinely good inventory tools costs nothing. So we built them. And we’re giving them away.
Who’s behind the bar.
Richard Jamison
Creator & Developer
Bar industry veteran turned entrepreneur and developer. Richard has done more inventory counts than he cares to admit — which is exactly why he built the machinery to make it painless. He brings the bartender’s eye and the engineer’s precision.
Bill
General Manager, Agave & Rye — Cleveland
Bill didn’t just wish us luck. He opened his restaurant, gave us his bar, his team, and three weeks of real inventory sessions. That kind of partnership is the difference between tools that demo well and tools that actually work.
Every tool was field-tested at Agave & Ryein downtown Cleveland — three weeks of real counts, real data, and real feedback from bartenders who just want to go home on time. If you’re ever in the neighborhood, go support them. Good people running a great spot.
Built for the community.
Open Source Barware isn’t just free spreadsheets. We connect bartenders with the organizations that support the craft — from the United States Bartenders’ Guild to education programs and mental health resources built specifically for hospitality workers.
The bar industry takes care of everyone else. We think it’s time someone built tools that take care of the bar industry.
Free means free.
Every bar — from the dive on the corner to the craft cocktail lounge downtown — deserves proper inventory tools. Not everyone can afford $200/month software. We don’t think they should have to.
We build in the open. We test in real restaurants. We give the results to the industry. No premium tier. No paywall. No strings.
