Turns any idea into a live single-file HTML prototype in minutes — inline CSS/JS, CDN-only dependencies (cdnjs), mobile-first, seeded with believable fake data, interactive states wired — ready to open in a browser or paste as a Claude artifact. Use when the user says "prototype this", "show me a working demo", "make this idea clickable", "can we test this flow before building it", or needs to feel an interaction instead of reading a spec.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Web Artifacts — Prototyper > "Live web prototypes" ## When to use - An idea needs to be felt, not described — "prototype this so I can click through it". - A stakeholder demo is imminent — "I need something to show in an hour". - A flow is contested — "would users even get this? build it and let's see". - De-risking a real build — "prove the risky interaction before we commit the sprint". ## Workflow 1. **Scope-cut first: what is the ONE interaction to prove?** Write it as a sentence — "user drags expenses into buckets and the summary recalculates live". Everything not serving that sentence gets faked or cut. 2. **Choose the thinnest stack that proves it.** Default is vanilla HTML/CSS/JS in one file. Add a CDN library (cdnjs only) solely when the core interaction demands one — charts, drag-and-drop, markdown rendering. 3. **Seed believable fake data.** 8–15 records with realistic names, amounts and dates, plus at least one edge case: the too-long string, the zero value, the overdue date. Declare it as `const DATA = [...]` at the top of the script so reviewers can tweak it live. …

How to install
mdr add alebgl77/claude-inc/web-artifacts@sha256:3f3e33a889fd1854The line at the top of this page pins the label git:20260711.2713ff9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
