CRediT Matrix

A web app for writing the contribution statement of a paper: who did what, in the 14 roles of CRediT (Contributor Roles Taxonomy). It was formerly called CRediT Generator. Add your contributors, give each of them their roles, and copy a statement for the manuscript, a contribution heatmap figure, or files for journal submission systems: JATS4R XML, CSV, JSON, and Markdown.

Each co-author can check their own row through a link, and everything runs in your browser: only the ORCID and DOI lookups, the fetch of ORCID's public keys and the hosted site's cookieless Cloudflare Web Analytics beacon leave it. CRediT Matrix is an independent project. It is not affiliated with or endorsed by NISO.

First run	Statement & export

Quick start

Run it yourself (Node ≥ 26, pnpm ≥ 11):

git clone https://github.com/simonvanlierde/credit-matrix
cd credit-matrix
pnpm install
pnpm dev            # → http://localhost:3000

Or use the same logic elsewhere:

• the credit-matrix package and CLI, for Node and the browser
• the <credit-matrix> element, to show a statement and heatmap on any web page
• the Quarto extension and MyST plugin, to write the statement from your manuscript's front matter

The CRediT census in census/ is a separate Python pipeline that reads roles from open-access papers, for the Published practice tab and a public dataset.
