Slipstream — bar website with reservations, events and browser games
A complete website for a motorsport-themed bar (demo with a fictional brand): customer accounts, table reservations with a board-game library, event sign-ups, a no-code manager panel and three built-in 2D racing and city games.

Overview
Overview
Slipstream is a full website for a motorsport-themed bar. It goes far beyond a presentation page: guests create accounts, book tables together with a board game from the bar's library, sign up for events and compete in three browser games, while managers run everything from a no-code admin panel.
Highlights
- Table reservations with configurable capacity, durations, zones, lead time and auto-confirmation; the database prevents overbooking tables and games.
- Events with seat limits, per-booking limits, ticket links, check-in at the door and Excel export.
- Manager panel: texts and images, opening hours (including past-midnight closing), contact, menu, gallery, leaderboards, users and roles, legal pages — no code required.
- Three 2D games written from scratch on HTML5 Canvas: Moto Grand Prix, Rally and Grand Theft Slipstream — with leaderboards for account holders and guests.
- GDPR by design: data export and deletion for customers, cookie notice, privacy/terms/cookie templates and an OpenStreetMap embed that loads only on demand.
- Zero running cost architecture: static hosting plus Supabase free tier, with security enforced in the database through row-level security policies.
Try it
The brand name, address and contact details in the demo are fictional. The live demo runs in demo mode — all data is stored only in your browser, so you can freely create an account (the first account becomes administrator in the demo) and explore the manager panel. The games can also be played directly from the games section.

Case study
Challenge
The bar needed more than a menu page: a way to fill tables on quiet nights, manage events and board games without double bookings, and give regulars a reason to come back — all with no monthly software costs and without the staff having to touch code.
Solution
A dependency-free static frontend (HTML, CSS and JavaScript modules) backed by Supabase. All business rules — capacity, game copies, who may confirm a booking — are enforced in PostgreSQL with row-level security, so they cannot be bypassed from the browser. A demo backend with the same interface allows the whole site to run offline for testing. The games share a small custom engine (track splines, camera, input, synthesised engine sound) to stay lightweight.
Results
A complete, documented product that can be deployed for free on GitHub Pages or Cloudflare Pages in about ten minutes. Managers can operate events, reservations, the board-game library, menu and legal texts on their own. The three games run instantly in the browser on desktop and mobile — try them on this site.
