Spijs & Vree

Deciding what to eat is a surprisingly hard group decision. Spijs & Vree turns it into a game: the members of a household swipe through recipes in a shared session that syncs in real time, each whenever it suits them until the session closes, and when enough of them agree, the recipe goes on the meal plan.

How a match works

• Any veto blocks a match.
• In a two-person household, both have to agree.
• With three or more people, a strict majority of those who have swiped on a recipe wins, and a Super Like breaks an exact tie.
• No-Go vetoes are rationed per session by role: members get one, organisers three, and admins have no limit.

The rest of the app

• Every swipe feeds an Elo-style ranking, so household favourites rise over time.
• Filters can boost, require, avoid or exclude recipes by tag, diet, season or course, and rule out allergens entirely.
• Households are shared through invite codes, with admin, organiser and member roles.
• Matches flow into a meal plan and a shopping list, and the app installs on your phone like a native app.

Two versions

The first version was a Blazor WebAssembly prototype. The current version is a rewrite in Next.js and Supabase, with realtime swipe sessions and row-level security on every table.
