Everything Map Blueprint does

The complete list of tools and capabilities, from live collaboration to a REST API. If you're deciding whether it fits your table or your team, this is the whole picture.

Real-time collaboration

• Live shared editing, everyone opens the same link and paints the same map at once.
• Live cursors, see where everyone else is working in real time.
• Presence list, see who's currently online in the map.
• Instant sync, every change appears for everyone immediately.
• No accounts, nobody has to sign up, just share the link.

Drawing tools

• Paint, drag to fill cells with a zone colour.
• Erase, clear painted cells.
• Rectangle fill, drag a box to flood a whole area at once.
• Adjustable brush, a paint/erase footprint from 1 to 30 cells.

Zones & custom palette

• Your own zone types, define each with a name and a colour, no theme packs to install.
• Any genre, fantasy, sci-fi, horror; build the palette your world needs.
• Rename safely, tiles reference zones by key, so renaming a zone never breaks the map.

Markers & labels

• 130+ icon markers across 8 browsable categories, settlements, terrain, plants, water, danger, treasure, creatures and magic.
• Scalable, size any marker from 0.3× to 16×.
• Text labels, drop place names anywhere, up to 200 characters each.

Layers & dungeons

• Stack layers, keep dungeon interiors, building interiors or separate continents on their own layers under the overworld.
• Linked entrances, turn a marker into a doorway that travels to another layer.
• Reorder, arrange the layer order however you like.

Measurement

• Line, measure a straight distance.
• Path, measure a multi-point route.
• Area, measure a polygon's area and perimeter.
• Pin & clear, keep finished measurements on the map or wipe them.
• Dual units, a fixed 1:10 grid (one cell = 10 world units) so a plan lines up with engine coordinates, like Unity.

The canvas

• Infinite map, the world auto-expands as you paint outward; only painted cells are stored, so big mostly-blank maps stay small.
• Region-streamed, huge maps load in pieces so they stay fast.
• Zoom & grid, zoom in and out and toggle the grid overlay.
• Live minimap, a resizable overview you can click and drag to jump around.
• 100-step undo, a deep undo history for fearless editing.

Maps, import & export

• Multi-map dashboard, create, rename, duplicate, export, import and delete maps, unlimited.
• JSON round-trip, every map is one plain-text .json file you can export, hand-edit, version-control and re-import.
• PNG export, save the current view as an image for your notes or Discord.
• Safe imports, imports never overwrite, and legacy single-layer files upgrade automatically.

Self-host, privacy & white-label

• One-file app, download and run on Windows, macOS or Linux, nothing to install.
• Your data stays yours, maps live in plain JSON files in a data/ folder you control.
• Password protection, lock a group behind a shared password (or skip it).
• White-label, set your own app name, accent colour, favicon and logo.

HTTP API

A Bearer-token REST API under /api/v1 lets you list, read, create, replace, rename, duplicate and delete whole maps programmatically, the request body is the same JSON as an export. It's off until you generate a token. See the API reference for details.

Platform & access

• Touch & tablet, one-finger draw, two-finger pan and zoom, large touch targets and a slide-in drawer.
• Seven languages, the app UI is available in English, Spanish, French, German, Italian, Portuguese and Chinese.
• Runs in the browser, no Docker, no Node, just a modern browser.

Keyboard shortcuts

• b paint · e erase · g fill · t label · m marker · r measure · h pan.
• Ctrl/Cmd+Z undo · Enter finish a measurement · Esc cancel · hold Space to pan.

That's the whole toolset. It started as the way we plan our own game world, and it's free for you to use for yours.
