prototypeMC-Architect is a browser-based 2D top-down Minecraft structure designer — paint blocks onto a grid, tweak per-block states, and slice through Y-layers to plan 3D builds in a flat interface.
Overview
A 2D top-down Minecraft structure designer that works like an architectural blueprint tool. Paint blocks onto a grid, fine-tune per-block states from the full Bedrock block catalog, and step through Y-layers to plan 3D builds in a flat, fast interface.
What it does
- Paint & place blocks on a top-down grid using the full Bedrock block palette (searchable, categorized).
- Slice vertically through Y-layers (Y=-64 to Y=320), with the layer below rendered faintly for spatial context.
How it's built
- Angular standalone components, OnPush change detection, signals throughout.
- HTML5 Canvas rendering — no DOM grid — for performance on large structures.
@minecraft/vanilla-datapowers block definitions and states.- Supabase for auth (magic link + OAuth) and cloud saves, with row-level security scoped per user.
localStorageautosave mirrors every edit for crash recovery, independent of cloud save.- 100% client-side — no server, no install, runs from any static host.
