Posy is a link-in-bio page (a Linktree alternative) with six hand-made looks. A page is one JSON document, so you can edit it in the studio, hand it to an AI, or script it. It is open source and you can host it yourself.

Quickstart

Make a page on posy.page in about two minutes.

Looks gallery

Desk, Washi, Lofi, Painted, Cobalt and Night.

Connect an AI app

Claude, ChatGPT, Cursor, VS Code, Claude Code and Codex.

Self-host

Docker, Compose, Vercel with Turso, or any Node host.

​
How it fits together

  • The studio is the editor at posy.page. You paste a link and Posy picks the right tile.
  • The page file is a small JSON file any chat can write. Load it at /new. See the page file.
  • The MCP server lets an AI app edit your page directly. Everything it does lands in your draft until you publish. See MCP tools.
  • The REST API and CLI do the same from scripts. See the API reference.
