I'm a bar owner and have been behind the stick for years. Every bar ▎ inventory system I found was either a monthly subscription or locked your ▎ data behind a paywall. Pour cost is simple math — it shouldn't cost ▎ $200/month. ▎ ▎ So I built Open Source Barware — a free, open-source set of tools for ▎ counting inventory, tracking pour cost, and managing bar operations. It ▎ includes downloadable spreadsheet templates, a browser-based inventory ▎ sandbox, and a standalone Flask/Chrome program you can run locally with zero ▎ internet required. ▎ ▎ Stack: Next.js 16 + Tailwind (static site on Cloudflare Pages), Flask for ▎ the local program, GPL-3.0 licensed. ▎ ▎ GitHub: ▎ ▎ Everything is free, no signup, no tracking. Would especially love feedback ▎ from anyone who's worked in hospitality or has opinions on the spreadsheet ▎ templates — the inventory counting workflow is where most of the real-world ▎ value lives.

Love that it stays local-first and only pings the cloud when you snap an invoice photo, feels like the right default for a bar's sensitive stock data.

@sefapw9i Exactly. The inventory/count/variance workflow is local-first and completely free: no subscription and no account. Invoice photo reading is optional and should be treated as a helper. Clean printed invoices work best; messy handwriting still needs a human check. Anyone who wants help testing it in a real bar can reach me at Me@rbj.
