What you get

Replace your Markdown parsing stack with one HTTP call.

XSS Protection

Server-side sanitize-html strips <script> tags, event handlers, iframes, and other dangerous HTML before it reaches your app.

Simple REST API

POST your Markdown, get sanitized HTML back. GFM tables, code blocks, and task lists included. No libraries to install or update.

No dependency maintenance

Stop tracking CVEs in marked, remark, rehype, and sanitize-html. We handle parsing and updates — you just call the endpoint.
