Twenty-six integrations ship, in six groups. Each says whether Delta can install it or whether you install it yourself.
More integrations are in progress. This table is the set at the time of writing.
Forms
Seven form plugins, nine integrations counting the paid editions. The plugin owns mail, spam and submissions; the agent creates the form and places it in your design.
| Plugin | Install |
|---|---|
| Contact Form 7 | Delta |
| WPForms Lite | Delta |
| Fluent Forms | Delta |
| Forminator | Delta |
| Ninja Forms | Delta |
| WS Form LITE | Delta |
| WPForms | You (premium) |
| Gravity Forms | You (premium) |
| WS Form PRO | You (premium) |
Gravity Forms, WPForms and WS Form PRO are paid plugins, so Delta cannot fetch them. Install the plugin yourself and the integration becomes available on the next request.
Each plugin has its own set of field types, and the agent uses only the ones that plugin has. All of them have text, email, long text, a dropdown, checkboxes, a consent box and a submit button. The differences:
| Plugin | Phone field | Website field |
|---|---|---|
| Contact Form 7, Gravity Forms, Forminator | Yes | Yes |
| WPForms Lite | No | No |
| WPForms (paid) | Yes | Yes |
| Fluent Forms (free) | No | Yes |
| Fluent Forms Pro | Yes | Yes |
| Ninja Forms | Yes | No |
| WS Form (LITE and PRO) | Yes | Yes |
To create or change a form, the agent needs Fluent Forms 6.2.5, Ninja Forms 3.15 or WS Form 1.11 or newer. With an older version, Delta still shows and lists your forms. WS Form’s own abilities change or delete forms only while its Allow Updates and Allow Deletes settings are on.
Content types
Eight plugins for custom post types, taxonomies and fields. This is what the agent uses when a brief needs a catalogue.
| Plugin | Types and taxonomies | Fields | Install |
|---|---|---|---|
| Advanced Custom Fields | Yes | Yes | Delta |
| Secure Custom Fields | Yes | Yes | Delta |
| Custom Post Type UI | Yes | No | Delta |
| Pods | Yes | Yes | Delta |
| Meta Box | With companion | Yes | Delta |
| ACF PRO | Yes | Yes | You (premium) |
| Meta Box AIO | Yes | Yes | You (premium) |
| JetEngine | Yes | Yes | You (premium) |
Advanced Custom Fields is the default proposal when a brief needs custom fields.
JetEngine also brings relations, Query Builder queries, Custom Content Types, options pages and glossaries. The agent creates them through JetEngine itself and prints them with loops of their own; see Loops and pagination. Needs JetEngine 3.9.
Advanced Custom Fields and Secure Custom Fields cannot run together, because they deactivate each other. Custom Post Type UI does not do fields, so pair it with one of the others.
Commerce
WooCommerce, which Delta can install. It is large enough to have its own page.
Design systems
Two plugins for sites that keep their styles outside Delta. Both are paid, so you install them yourself.
| Plugin | Does | Install |
|---|---|---|
| Automatic.css | Your site.css loads after automatic.css. The agent reads its variables and settings, and changes settings after a snapshot | You (premium) |
| SchemaWP | Runs SchemaWP’s own Automatic.css tools through Delta, with a snapshot before each change. Needs Automatic.css 4 | You (premium) |
See Use your own design system.
SEO
Two SEO plugins, and one for redirects. The SEO plugin owns the page head; the agent sets a page’s search title and description in the same request as its content. See SEO and Redirects.
| Plugin | Does | Install |
|---|---|---|
| SureRank | Titles, descriptions, share tags, robots, sitemap and schema. Its own abilities need Enable MCP on | Delta |
| SureRank Pro | Adds per-type templates, redirects and more schema types | You (premium) |
| SEOPress | Titles, descriptions, share tags, robots, sitemaps and schema. Its own abilities need Expose abilities to AI agents on | Delta |
| SEOPress PRO | Adds redirections, schemas, AI generation and the technical audit | You (premium) |
| Redirection | Redirects, groups and the 404 log. A redirect is proposed when a page’s URL moves | Delta |
Needs SureRank 1.10, SEOPress 10 or Redirection 5.10 or newer.
Publishing
Simply Static, which Delta can install. It exports the site as static HTML; the agent checks, starts and reads back the export. See Static export. Needs Simply Static 3.8.18.
Version requirements
Each integration records a minimum version and the version it was last tested against. If a plugin is older than the minimum, the integration will not activate, and the agent reports the version it needs.
