Artifacts hosts the HTML reports, Markdown specs, and JSX prototypes your agents produce — each with version history, access control, and a URL that never changes.
Three steps from a finished agent output to a permanent, shareable URL.
A report, spec, prototype, or one-off tool, written as HTML, Markdown, or JSX.
One call from the CLI, REST API, or MCP stores the content and returns a permanent URL.
Open it in the browser, control who can see it, and update it without losing old versions.
Drop in the Claude Code run here: generate a PR report, publish the URL, then append v2.
Everything an artifact needs once the model is done writing it.
Every artifact gets one stable link. No temp paths, no re-uploads, no attachments lost in a chat log.
Each update saves a new immutable version. Diff any two, or restore an earlier one.
HTML renders sandboxed, Markdown is sanitized, and JSX runs on a Preact runtime. Built for untrusted output.
Public, private, email allowlist, or a scoped share link. The URL stays the same.
Publish and update from the CLI, REST API, or MCP, with the same model and permissions humans use.
Move an artifact from your personal workspace into a team when it becomes shared context.
Reports, plans, reviews, and one-off tools.
Artifacts turns each one into a page you can share.
Compare directions side by side, then point at the one worth expanding.
Turn a long plan into milestones, data flows, snippets, and review checkpoints.
Group diffs by risk, annotate the important paths, and guide the reviewer’s attention.
Synthesize Slack, Git history, docs, and issues into a page people will actually read.
Use diagrams, tabs, sliders, and toggles when text alone would bury the point.
Build one-use interfaces for shaping JSON, CSV, prompts, or configuration by hand.
Chat text is giving way to outputs you can
open, inspect, and share.
HTML is the new markdown.
Hot tip: try ask for HTML.
There is evidently an opportunity for a microservice for this.
Artifacts are a game changer for how I work with Claude.
Markdown is a report. HTML is an interface.
HTML can drop in SVG diagrams, interactive widgets, and in-page navigation.
