Every site I build starts the same way. A field plugin, a form plugin, an SEO plugin, and then four or five one-trick utilities for the things WordPress does not do by itself. Four admin menus, four sets of conventions, four things to keep updated.

So I wrote one plugin that does those four. It is free on wordpress.org and it is called Ultivo Toolkit.

What is in the free version:

• Custom fields. Visual builder, location rules, 33 field types including repeater. Stores data in exactly the same meta pattern as ACF, so existing field data keeps working and there is a migration tool for field groups and acf-json.
• Forms. Drag and drop builder, entries in the admin, notifications, file uploads outside the media library, optional spam protection.
• SEO. Title and description templates, Open Graph, sitemap. It prints nothing at all while Yoast, Rank Math or AIOSEO is active, so you can install it next to what you already run.
• Seventeen switches for the usual chores: duplicate posts, SVG and AVIF uploads, a custom login URL, manual content ordering, limit login attempts, redirects with a 404 log, SMTP, admin menu organiser. All off by default.

It needs WordPress 6.0 and PHP 7.4, so it should install on just about anything you still maintain.

Three things I would want to know if someone posted this at me:

Is it heavy? Each of the four parts can be switched off, and when it is off it registers nothing: no menus, no screens, no hooks, no queries. Measured on a stock install, the whole thing adds eight queries to a front end page.

What if I uninstall it? Your content stays. Field values go into ordinary post meta, the same shape ACF uses: client holds the value, _client remembers which field it came from. Delete the plugin and those rows are still on your posts, and get_post_meta() still returns them. Nothing is kept in a table of its own, and nothing is cleaned up on uninstall. You lose the builder, not the content. That is also why you can leave ACF switched on while you try this: it never switches off a plugin from someone else, it just points out where the two overlap and lets you decide.

Where is the catch? There is a paid version. Pro adds Blueprints (export your post types, taxonomies, field groups and forms to a file and import them on another site), Flexible Content and the Clone field, and it starts at $49 a year for one site. Everything I listed above is in the free version and stays there, including repeater, options pages and the ACF migration. Nothing is sent to us, ever. Two features do reach an outside service: spam protection if you switch it on, and the map preview in the admin.

It went into the directory five weeks ago and has had six releases since, so it is new and barely used, but it is not parked. That is exactly why I am posting. If you build sites for a living I would rather hear what is missing than get a download: what would stop you switching?
