What is Posy

Posy is a link-in-bio page that looks hand-made. You pick a look, add your links, and publish. Edit it yourself in a calm studio, or ask your AI to do it for you. Your page is one small JSON file you can take anywhere.

The looks

The same links, drawn as a wooden desk with polaroids, a Japanese print, a desktop left open, a watercolour, a two-ink print or a netrunner's screen. Each look has four palettes, and you can switch any time.

On posy.page, Painted, Desk and Lofi are free, and the others come with Pro. Self-hosted, every look is unlocked. See them live in the looks gallery.

Tiles, palettes and layouts

Three layouts: bento (a grid), list (one column) and canvas (place tiles freely). Photos can be printed natural, mono, dither or ascii. On top of each look's palettes: Cream, Lavender, Mint, Sky, Peach, Paper, Blush, Sage, Midnight, Mocha, Dusk and Ocean, any accent colour, and font pairs.

Make your page

Claim your name at posy.page. Paste a link anywhere to add a tile, drag to arrange, and press Publish. Your page is live in a minute.

Just looking? Open posy.page/new, paste a few links and see your page before you sign up.

Free, Pro and self-hosted

Pro is $5 a month or $48 a year. Your page works the same everywhere: Settings → Download page.json on one, Import page.json on the other.

Connect your AI

Posy has a hosted MCP server, so your AI can make and edit your page. You sign in with your Posy account; there is no key to copy. Everything it does lands in your draft, and nothing goes live until you, or it, publish.

One click

A few steps

claude mcp add --transport http posy https://posy.page/api/mcp   # Claude Code, then /mcp → Authenticate
codex mcp add posy --url https://posy.page/api/mcp               # Codex

In ChatGPT, open Plugins, press +, choose Add custom MCP server, paste the URL and pick OAuth. On your own server, use https://YOUR-POSY/api/mcp. Posy is in the official MCP registry as io.github.Himanshu-Sangshetti/posy.

No connector? Hand it a page file

Any chat can write your page as one small JSON file. Paste it at posy.page/new and it becomes a page.

Or skip the file: an AI can hand you a link that opens a live preview, no sign-in needed.

https://posy.page/new?name=Mira%20Sol&look=washi&links=https://github.com/mira,hi@mira.so

The page file, MCP tools, REST, llms.txt and the CLI

{
  "posy": 1,
  "name": "Mira Sol",
  "bio": "Writer and editor.",
  "location": "Lisbon",
  "look": "washi",
  "links": [
    "https://substack.com/@mira",
    "https://x.com/mira",
    "hi@mira.so",
    { "heading": "Writing" },
    "https://mira.so/letters"
  ]
}

Every field: the page file.

export POSY_URL=https://posy.page POSY_API_KEY=posy_...
npm run posy -- add https://github.com/owner/repo --size w
npm run posy -- theme --preset moonlit --layout list
npm run posy -- publish

Run it yourself

Or with Docker:

git clone https://github.com/Himanshu-Sangshetti/posy.git && cd posy
docker build -t posy . && docker run -p 3000:3000 -v posy-data:/data \
  -e NEXT_PUBLIC_SITE_URL=http://localhost:3000 -e BETTER_AUTH_URL=http://localhost:3000 \
  -e BETTER_AUTH_SECRET=$(openssl rand -base64 32) posy

Open http://localhost:3000 and sign up: the first account owns the instance, and every look is unlocked. Domains, backups and every setting: self-hosting guide · .env.example

Built with

Next.js 16 · React 19 · TypeScript · Tailwind CSS 4 · Motion · dnd-kit · shadcn/ui · Better Auth · Drizzle + libSQL · Zod · MCP

One schema, src/lib/schema.ts, describes a page. It drives the JSON Schema, the REST API, the MCP tools and the editor, so they never drift apart.
