OpenResto is a self-hosted booking system that lets restaurants, bars, and cafes take reservations from their own website instead of paying a platform for every cover. Guests browse your locations, pick a party size, date, and time, and the exact table is held for five minutes while they type a name and email, with no account to create and nothing to install. Slots are grouped into Lunch, Dinner, and Off-Peak so guests jump straight to the sitting they want, and confirmation pages offer calendar export, reminders, and directions. Staff run the night from a dashboard with a live bookings list, a day timetable, and a service view, extending or cancelling reservations and pausing new bookings during private events without editing any configuration. One instance manages several restaurants, each with its own floor sections such as Patio or Bar, opening hours in its own timezone, policies, and pacing rules. The whole guest experience carries your name, colors, and icon, and the same screens can even be published as your own phone app. Every admin action lands in an append-only activity trail, and scoped API keys let your other tools read bookings without ever seeing guest contact details. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
