In their own words
Oxygen
Oxygen is a visual website builder for WordPress that works through manual editing or compatible AI agents. It installs as a plugin on an existing WordPress site, including local, staging, or live installations; a hosted demo is also available. The editor provides controls for Flexbox, CSS Grid, responsive breakpoints, semantic HTML, and HTML, CSS, JavaScript, and PHP code blocks. Reusable components, CSS variables, selectors, and JSON export for design tokens support design-system work. Dynamic fields, conditions, and query loops can use ACF, Meta Box, and ACPT content. Oxygen's Agent Connector, MCP server, and Abilities API support agents such as Claude, Codex, Cursor, and OpenCode, which can build pages, content types, templates, plugins, and content. The complete editor and AI tooling are free to try through a plugin, local setup, or hosted demo; the demo expires after four hours. AI credits are not sold by Oxygen, so users bring an agent under the vendor's own plan. Listed lifetime-billed plans include Basic at $129 a month, WooCommerce at $149 a month, and Ultimate at $179 a month. A separate lifetime license is $199.50 as a one-time purchase.
