About PluginProbe

A source code browser for the WordPress plugin ecosystem.

What is PluginProbe?

PluginProbe lets you read the source code of any plugin published on WordPress.org, in any released version or in trunk, without downloading a zip or checking out SVN. Files are served with syntax highlighting, a file tree, and a permalink for every line.

Code is read live from the official WordPress.org SVN repository. PluginProbe adds navigation, addressable lines and machine-readable endpoints on top of it. It is not affiliated with WordPress.org or Automattic.

Why line-level permalinks

A vulnerability report is only as good as its references. Pointing at a file is not enough when the reader has to find the affected call themselves, and a pasted snippet loses the surrounding context and the version it came from. PluginProbe gives every line of every released version a stable URL, so a report can link to exactly the code it describes and the reader lands on it with one click.

Who is it for?

Security researchers
Cite the exact lines a finding affects, and show what changed between the vulnerable release and the fix.
Developers
Read how another plugin solves a problem, or check what a dependency actually does before you ship it.
AI agents
Fetch plugin source over plain HTTP with stable, documented URLs and a raw endpoint. No zip handling, no SVN client.

How it works

1
Index
A crawler queries the WordPress.org API to discover new and updated plugins, and stores plugin metadata and version history. Any plugin not indexed yet is fetched the first time someone opens it.
2
Browse
File listings and file contents are read from the WordPress.org SVN repository on demand and cached. Nothing is mirrored permanently, so what you read is what the repository holds.
3
Link
Every line has an anchor. Select a line or a range and copy a permalink, the lines themselves, or a Markdown snippet ready to paste into a report.
4
Automate
Raw file endpoints, an XML sitemap and llms.txt make the same content available to scripts and AI agents without scraping the HTML.

Data sources

  • WordPress.org Plugin API plugin metadata, version history, download links
  • WordPress.org SVN file listings and file contents, read live
  • WordPress.org downloads release archives, used for file listings and zip links

All data comes from public APIs and repositories. PluginProbe does not access or store private plugin data. See the agent and crawler reference for how the crawler identifies itself.
