framejs.ioOpen web artifacts, yours to embed anywhere

Same idea as a Claude or ChatGPT artifact — one file of browser code that just runs. Except this one is a URL of its own: embed it live in a notebook, paper, or slide, wire it to data, cite an exact version, fork it, self-host it. Open source, and nobody needs an account to open what you made.

Intro

Quickstart

Use it in Claude

Create new

Slide deck

URL: https://framejs.io/j/8e5d5eed5c...

The URL shareable and editable (with AI)

Use it in Claude — no install

Paste one connector URL into Claude Desktop, web, or mobile. Claude builds and edits your artifacts in the conversation — and each one leaves the chat as a link that runs on its own. No terminal, nothing to download.

Add the connector

Edit with AI in your coding agent

One-line skill install for Claude Code, Cursor, Gemini CLI and ~40 others — describe what you want, and reference local files.

The URL is the artifact

Code and state both live in the URL — no server copy, nothing to deploy. Copy the link and anyone can run it, exactly as you left it.

Embed it live, anywhere

One iframe drops the running artifact into a paper, an LMS, a docs site, or a slide. Not a screenshot and not an export — the real thing, still interactive.

Notebook Widgets

Use any metaframe as an interactive Jupyter or marimo widget with the metaframe-widget Python package. Values pass both ways, so your Python and the artifact stay in step.

Connect Metaframes

Wire inputs and outputs between metaframes, so several artifacts compose into an app, a workflow, or a dashboard instead of sitting in separate links.

Open source, and yours to host

The rendering runtime is MIT-licensed and the URL format is documented. Fork it, run it inside your own network, and every artifact keeps working.
