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.

Three steps: 1, pick a look. 2, add your links, and Posy turns each one into the right tile. 3, publish to posy.page/you, or ask your AI to do all three.

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.

A short tour of the looks on a desktop: Desk, Washi, Lofi, Painted, Cobalt and Night.

Desk: a wooden desk with polaroids, a record and letters.Washi: a Japanese print with rice paper, ink and a red seal.Lofi: a desktop left open where every tile is a window.
Painted: watercolour paper, letters and wax seals.Cobalt: a vintage print in two inks, under a crescent moon.Night: a netrunner's screen with one signal colour.

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.

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.

A few steps

Set up ChatGPT Set up Claude Code Set up Codex

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.

A JSON page file on the left, with name Mira Sol, look washi and a few links. An arrow points to the same page rendered in the Washi look on a phone.

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

Run it yourself

Deploy with Vercel

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

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.

Issues and pull requests are welcome. Start with CONTRIBUTING.md.

  • Add a look. A look is a .tsx and a .css file plus a lab page to check it in every palette. The steps: Adding a look.
  • Pick up an issue. Good first issues and look ideas are a nice place to begin.
  • Before a PR: npm run check, npm test, and npm run e2e for UI changes.
