The strongest CMB2 alternative for most sites is Advanced Custom Fields, which gives you a visual field builder and a friendly API instead of CMB2’s code-only approach. If you prefer a free developer framework close to CMB2’s philosophy, Meta Box defines fields in PHP, while Pods adds custom content types and fields through its own interface. We ranked these from our index of 55,000+ WordPress plugins.

Why people switch from CMB2

• CMB2 has no user interface and is configured entirely in code, so people wanting a visual field builder move to Advanced Custom Fields or Pods.
• It handles meta boxes but not custom post types or taxonomies, so people wanting content types too move to Pods or Meta Box.
• Developers wanting a maintained framework with commercial extensions move to Meta Box or Carbon Fields.
• Teams building full theme option panels move to Redux Framework.

Advanced Custom Fields – Overall replacement

Advanced Custom Fields is the most widely used custom fields plugin, pairing a visual field builder with a clean template API. Against CMB2, it replaces code-defined meta boxes with a point-and-click interface that non-developers can use too. Its drawback is that repeaters, flexible content, and the options page live in ACF Pro, whereas CMB2 gives comparable structures for free in code.

Choose Advanced Custom Fields if you want a visual builder with the largest ecosystem and documentation.

Redux Framework – Theme options panels

Redux Framework is an options framework aimed at building settings and theme option panels rather than post meta. Against CMB2, it excels at large configuration screens for themes and plugins. Its weakness is fit: it is heavier than CMB2 and overkill if you only need a few custom fields on posts, and it has historically bundled promotional notices.

Choose Redux Framework if you are building extensive theme or plugin option panels.

Meta Box – Developer framework

Meta Box is a lightweight, developer-focused framework that defines custom fields in PHP and extends through a large set of add-ons. Against CMB2, it offers a more actively developed ecosystem with optional extensions for custom post types, relationships, and more. The catch is that most of those extensions, and the builder UI, are paid, so the free core stays code-driven.

Choose Meta Box if you want a modern code-first framework you can extend with add-ons.

Pods – Content types plus fields

Pods is a free, community-run tool that creates custom post types, taxonomies, and fields through a single admin interface. Against CMB2, it bundles content modeling and fields together with a UI, no code required. Its drawback is a steeper conceptual learning curve and an interface that feels less polished than ACF’s.

Choose Pods if you want to model content types and fields together for free.

carbon-fields – Code-based fields

Carbon Fields is a developer library for defining custom fields in code, loaded via Composer or a small plugin. Against CMB2, it offers a clean modern API and is a natural fit for theme and plugin developers who want fields in version control. The drawback is that it has no admin UI at all and less momentum than CMB2 or Meta Box, so community support is thinner.

Choose carbon-fields if you want a code-only fields library with a modern API.

When to stay on CMB2

Stay on CMB2 if you are a developer who wants meta boxes defined in code, in version control, and free of a heavy UI. It is stable, dependency-free, and gives you repeaters and complex field groups without a paid tier. If your fields ship inside a theme or plugin you distribute, CMB2’s code-first, license-friendly approach is hard to beat.

How we ranked these

Every plugin here is scored by the WPS Score, a single 0 to 10 rating built from 21 signals covering maintenance, support responsiveness, compatibility, performance, and ratings quality across our index of 55,000+ plugins. Rankings are derived from that data, not editorial preference, and no plugin author can pay to change a score. How the WPS Score works.

Frequently asked questions

What is the best alternative to CMB2 for non-developers?

Advanced Custom Fields is the best choice for non-developers because it offers a visual field builder and does not require writing code. Pods is another option that adds a user interface and also lets you create custom post types and taxonomies alongside fields.

Is CMB2 still maintained?

CMB2 is an open-source, community-maintained framework and remains stable, though its development pace is slower than commercially backed tools like Advanced Custom Fields or Meta Box. It continues to work well for defining custom fields and meta boxes in code.

Can I create custom post types with these plugins?

CMB2 handles fields and meta boxes but not custom post types. Pods and Meta Box can create custom post types and taxonomies in addition to fields, while Advanced Custom Fields added custom post type registration in its Pro version.

The verdict

The best all-round CMB2 alternative is Advanced Custom Fields for its visual builder and ecosystem, while Meta Box suits developers wanting a code-first framework and Pods those who need content types and fields together for free. If you distribute code and want fields in version control without a UI, staying on CMB2 is entirely valid.
