ChowOS is a free restaurant point of sale (POS) system. One system covers point of sale, server handhelds, kitchen display with station routing, a live floor plan, reservations and waitlist, QR and online guest ordering, staff PINs, roles and schedules, and a back office with reports, CSV export and end-of-day close. Every feature is free on every device, with no subscription and no contract. ChowOS runs on off-the-shelf Android tablets and phones or in a web browser, prints to Epson or Star network printers, and works with your existing card terminal or built-in card payments through Stripe. Setup is self-serve, and a live demo is available at chowos.com/demo without an account.
