Every WordPress site accumulates plugins the way a junk drawer accumulates cables — each one arrived for a reason, and nobody's sure which ones still matter. So when teams plan a migration, they naturally ask: what's the equivalent of each of my 20 plugins on the new platform? It's the right question with a surprising answer: most WordPress plugins don't need an equivalent, because they exist to patch WordPress itself. Here's the plugin-by-plugin map.

Category 1: Plugins That Become Platform Features

SEO plugins (Yoast, Rank Math, AIOSEO)

Yoast alone runs on more than ten million sites, which says less about SEO being hard and more about WordPress not handling metadata natively. On a modern CMS, titles, meta descriptions, canonical URLs, sitemaps, and structured data are core fields and automatic outputs — EmDash's SEO surface covers all of it without an install. What no tool replaces is the strategy: keyword choices and content quality were never in the plugin.

Caching and performance (WP Rocket, W3 Total Cache, Autoptimize)

These exist because WordPress renders pages with PHP on every request and something has to memoize that work. Static-first platforms pre-render at build time — there is no request-time work to cache. This category doesn't get replaced; it gets deleted. The same logic applies to image-optimization and lazy-load plugins, which modern frameworks handle at build.

Security (Wordfence, Sucuri, iThemes)

Security plugins guard WordPress's attack surface: the public PHP runtime, the discoverable admin, the plugin ecosystem itself. When the architecture removes that surface, the guard tower has nothing to guard. You still need platform-level security — authentication, access control, updates — but it's the CMS's job, not a plugin subscription.

Backups (UpdraftPlus, BackupBuddy)

When templates live in git and content lives in a managed database, backup stops being a plugin and becomes version control plus standard database snapshots — boring, reliable infrastructure instead of a scheduled ZIP upload to Dropbox.

Category 2: Plugins That Become Structured Fields

Advanced Custom Fields (ACF)

ACF's two million installs are two million votes for structured content — bolted onto a platform designed around a single content blob. In a modern CMS, custom fields are the native data model, not an add-on: you define content types with exactly the fields each needs, and they're versioned in code rather than click-configured. ACF users tend to feel most at home after migrating, because they were already fighting for this model.

Custom post type and taxonomy plugins (CPT UI, Pods)

Same story: content modeling is core functionality, defined in schema instead of a settings screen.

Category 3: Plugins That Become Services or Components

• Forms (WPForms, Gravity Forms, Contact Form 7): replaced by a form component talking to a form endpoint or service. WPForms' 6M installs prove the need is real — it just doesn't need to live inside the CMS.
• Analytics (MonsterInsights, Site Kit): these were wrappers around a script tag. Add the script tag — or better, a privacy-first analytics service — directly in the template.
• Email/SMTP (WP Mail SMTP): transactional email is an infrastructure concern; use a sending service configured at the platform level.
• Social sharing, related posts, table-of-contents: template components in the new world — built once, no update cycle, no per-page JavaScript penalty.

Category 4: The Ones That Deserve Real Planning

Be honest about the hard cases. WooCommerce isn't a plugin so much as a platform living inside your CMS — replacing it means choosing a commerce solution, a genuinely separate project. Membership and LMS plugins (MemberPress, LearnDash) similarly carry application logic that needs a deliberate destination. And niche vertical plugins — booking calendars, real-estate listings — need a per-case answer: a service, a custom feature, or a reason to phase the migration. If most of your site's value lives in this category, that changes the migration cost calculation and belongs at the top of your planning, not the end.

The Audit That Makes This Concrete

List your active plugins and sort them into the four categories above. A typical business site's list of 20 shrinks to: a form service, an analytics script, and one or two real decisions. That shrinkage isn't a loss — every deleted plugin is an update cycle, a license renewal, and a slice of attack surface you no longer own. Run the audit before exporting anything (the export guide covers rescuing the data plugins leave in your database), then slot the results into the migration checklist. If the audit itself convinces you the drawer is mostly patches, that's sign number two.
