Agents can already write, test and ship on WordPress. Here are the 100+ open tools that make it possible, mapped in one place.
Every hex is a real tool. Pick one to see what it does.
WordPress
Wider web
Adoption
An agent working on a WordPress site needs more than a model. It needs a way to write blocks the editor will accept, a description of the site it is changing, commands to act with, a sandbox to try things in, checks that say whether it got it right, and benchmarks to measure it against. Those are the seven layers inside.
Around them sit browser drivers, audits, linters, local stacks, crawlers and agent tools built for the wider web. The WordPress group focuses on reusable primitives over vendor-specific add-ons. Most are open source; source-available licences are labelled.
Ordered by category, then by adoption. Names link to the project. Model providers, hosting, CI and optional paid services may have their own costs.
