WPReadme Preview: WordPress Plugin readme.txt Preview Tool

WPReadme Preview is a free online tool that renders your WordPress plugin readme.txt file exactly like it will appear on WordPress.org. Paste or upload your readme.txt and see a faithful preview of the plugin directory layout before publishing, including the header block, description with Markdown support, installation instructions, frequently asked questions, screenshots, and changelog entries.

The built-in readme validator scores your file against official WordPress.org requirements and sorts every check into required, recommended, and optional categories, with a fix tip and a link to the relevant documentation for each failed item. Upload an existing readme.txt to start editing right away, load pre-built examples to learn the expected structure, then download the finished file. No registration is required, nothing is uploaded to a server, and the tool works on desktop and mobile.

The same engine is available as a free JSON API for developers and agents: POST readme.txt content to /api/parse to extract structured data or /api/validate to score it against WordPress.org requirements. The full surface is documented by an OpenAPI 3.1 specification at /openapi.json, with human-readable docs at /developers. No API key is required.
