What Oxygen is
Oxygen is a visual website builder for WordPress that can be used by hand or with compatible AI agents. It installs as a plugin on an existing local, staging, or live WordPress site, and a hosted demo is available. The editor provides controls for Flexbox, CSS Grid, responsive breakpoints, semantic HTML, and HTML, CSS, JavaScript, and PHP code blocks. Users can build reusable components, manage CSS variables and selectors, and export design tokens as JSON. Dynamic fields, conditions, and query loops support content from ACF, Meta Box, and ACPT. Oxygen’s Agent Connector, MCP server, and Abilities API support agents such as Claude, Codex, Cursor, and OpenCode; agents can build pages, content types, templates, plugins, and content on a real install. The complete visual editor and AI tooling are free to try, while the hosted demo expires after four hours. Paid plans are listed from $129 a month, billed lifetime; a 199.50 USD once-paid lifetime license is also listed. Users bring their own agent under the agent vendor’s plan.
