Overview

Description from the maker (original English)

A collaborative whiteboard your AI assistant can read, fill and show live, with changes you review.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

Before you install

Basic checks: 3 of 3 passed
Runs on the maker’s server: what you ask it goes through their server.
The registry lists no key to fill in.

You need

Runs in the cloudNothing to install; it connects over the internet

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Freero safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 2 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Freero

An original real-time collaborative whiteboard: an infinite canvas for teams to brainstorm, plan, diagram and run workshops together.

What's in it

Canvas — infinite pan/zoom, dot grid, minimap, snapping and alignment guides, multi-select, resize/rotate, groups, lock, undo/redo, copy/paste across boards, drag-and-drop import.
Content — sticky notes, 21 shapes, rich text, connectors (straight/elbow/curved, attached, labelled), pen + highlighter + eraser, images, emoji and stamps, frames, task cards, mind maps, tags, PDFs, video and audio that play on the board, and file cards for any other file.
Collaboration — live sync, cursors and selections, avatars, follow a collaborator, "bring everyone to me", emoji reactions, comment threads, owner/editor/commenter/viewer roles, share by invite or link.
Facilitation — voting sessions, a shared timer, presentation mode over frames.
Templates & export — 180 original templates in 18 categories; export PNG/JPG/SVG, frames to PDF, copy as image.
Dashboard — boards grid/list, search, filters, stars, live thumbnails, duplicate, sharing.

Run it

Requires Node 22+.

npm install

npm run dev # server on :4000 + web on :5173

Open http://localhost:5173 and log in with the seeded demo account demo@freero.app / freero123 (development only), or sign up. http://localhost:5173/board/local is an offline sandbox board that needs no server.

Production:

npm run build && npm start     # serves the built web app and the marketing site (apps/site) on :4000

docker compose up --build -d # or the full stack: proxy, 2 app replicas, Postgres, Redis, MinIO, Mailpit on :8080

Deploying for real: docs/deployment.md · every setting: docs/configuration.md · backups, monitoring, incidents: docs/operations.md.

Configuration: PORT (default 4000), FREERO_DATA_DIR (default ./data — the built-in PGlite database in data/pg + uploads), DATABASE_URL (use a real Postgres instead), DATABASE_POOL_MAX (default 10). Had boards from before the move to Postgres? Stop the dev server and run npm run db:import-sqlite once.

Develop

Command	What it does
`npm run check`	Architecture boundaries + typecheck + unit tests
`npm run verify`	Real-session end-to-end check: real server, real Yjs WebSocket clients, roles, persistence
`npm run new:feature -- …`	Scaffold a feature folder (see ARCHITECTURE.md)
`node scripts/ui-shot.mjs --url … --out …`	Drive the real UI in headless Chromium and screenshot it

Freero follows the Dune method: features are isolated folders discovered by reserved file names, every piece of state has one writer, and forbidden dependencies fail npm run check with an error that names the supported path. Read ARCHITECTURE.md before changing code.

Stack: React 18 + TypeScript + Vite, Yjs (CRDT) over WebSockets, Express + ws, PostgreSQL (pg; PGlite for dev/tests), Playwright for UI verification.
