Advanced Custom Fields (ACF) has been the default WordPress custom fields plugin for over a decade. It’s on 2 million+ active installs. It’s the plugin every WordPress developer knows. In 2022 it was acquired by WP Engine. In 2024 it became the center of a WordPress community dispute that led to WordPress.org forking it into Secure Custom Fields (SCF). Today, ACF is still the category standard — but the architecture hasn’t meaningfully modernized since the early 2010s.
Field Forge is the modern alternative. Custom table storage instead of wp_postmeta, a full ACF compatibility layer so your theme code keeps working, AI schema generation, TypeScript and GraphQL auto-generation, and a cheaper price. Built for WordPress in 2026, not 2016.
| Field Forge | Advanced Custom Fields (ACF) | |
|---|---|---|
| Entry paid price | $35/year (Personal, 1 site) | $49/year (Pro, unlimited personal sites) |
| Mid tier | $99/year (10 sites) | — (Pro covers personal only) |
| Agency tier | $169/year (unlimited) | $249/year (Agency, 10 sites) |
| Free version | Yes | Yes |
| Storage architecture | Custom table with indexes | wp_postmeta (legacy) |
| Performance on large sites | 3–10x faster queries | N+1 query problem |
| ACF code compatibility | Full compat layer | Native (it’s ACF) |
| AI schema generation | Yes (unique) | No |
| TypeScript generation | Yes (unique) | No |
| GraphQL SDL generation | Yes (unique) | No (requires WPGraphQL for ACF) |
| Schema versioning / rollback | Yes (unique) | No |
| Local JSON sync | Yes | Yes |
| 32 field types | ✓ | ✓ (similar count) |
| Repeater, Flex, Group, Clone | ✓ | ✓ (ACF Pro only) |
| Options pages | ✓ | ✓ (ACF Pro only) |
| PHP blocks (acf_register_block_type) | ✓ | ✓ (ACF Pro only) |
| WPGraphQL integration | Native (auto-register) | Via separate WPGraphQL for ACF plugin |
| Admin UI age | 2025+ | 2014-era |
Let’s be fair. ACF didn’t become the category leader by accident. It has real strengths:
Thousands of third-party plugins, themes, and tools integrate with ACF. When a new WordPress developer googles “how to add custom fields,” they find ACF tutorials first. The ecosystem advantage is real and will take years to match.
Since 2022, ACF is maintained by WP Engine’s team. They have resources, support staff, and a commitment to keep ACF working. For enterprise customers who need vendor stability over 10-year horizons, WP Engine’s backing is reassuring.
ACF has been in production on millions of WordPress sites for over 15 years. The bugs have been found and fixed. The edge cases are documented. For sites that prioritize “just works” over “latest features,” ACF is a safe choice.
Every WordPress agency, freelancer, and in-house developer knows ACF. Onboarding new team members is zero-cost because they already know get_field() and the visual builder. Training cost for switching to any alternative is real.
ACF stores field values in wp_postmeta. It’s the wp-standard way and it works for small sites, but it creates N+1 query problems on sites with many posts or complex repeaters. An archive page with 20 posts and 10 fields each = 200+ SQL queries. On a site where the database is network-attached (which is how most managed hosting works), this is hundreds of milliseconds added to every pageview.
Field Forge uses a dedicated wp_fieldforge_values table with proper indexing on (post_id, field_name), (post_id, field_group_id), and (parent_id, row_index). Combined with a batch_load() API and WordPress object cache integration, the same 20-post archive runs in 1 SQL query. Real-world benchmark: 3–10x faster on sites with 1,000+ posts.
Custom table storage feature →
Field Forge implements every ACF template function: get_field(), the_field(), have_rows(), the_row(), get_sub_field(), get_row_layout(), update_field(), acf_register_block_type(), and more. When Field Forge is active and ACF is deactivated, theme code using ACF functions keeps working — the calls resolve to Field Forge’s storage instead of ACF’s.
What this means: you can migrate from ACF to Field Forge in under an hour without rewriting a single template file. Your existing get_field() calls continue to work. Your existing have_rows() loops continue to work. Your acf_register_block_type() registrations continue to work. The only difference is where the data is stored.
No other “ACF alternative” plugin offers this. Migration from ACF typically requires rewriting every template reference, which is why most customers never actually switch despite being frustrated with ACF’s performance or pricing.
ACF compatibility layer feature →
Field Forge is the only WordPress custom fields plugin with AI-based field group generation. Describe what you want in plain English (“Hero section with title, subtitle, background image, and CTA button”), and the AI builds the complete field group — right types, sensible labels, correct defaults. 12 built-in templates + AI fallback for custom descriptions.
ACF has no equivalent feature. The closest thing in ACF’s ecosystem is “ACF Extended” which adds more field types, not AI generation.
AI schema generation feature →
Field Forge auto-generates .d.ts TypeScript definitions for every field group, plus GraphQL SDL output, plus automatic WPGraphQL type registration when both plugins are active. For teams building headless WordPress with Next.js, Astro, Nuxt, etc., this turns custom fields from a type-safety nightmare into a fully-typed API.
ACF requires installing WPGraphQL for ACF (a separate plugin maintained by the WPGraphQL team) for GraphQL integration, and there’s no TypeScript generation at all.
TypeScript generation → · GraphQL generation →
Field Forge tracks every field group change as a revision with author, timestamp, and full diff. Accidentally broke a field group? Rolled out a bad change? One-click rollback. No other WordPress custom fields plugin has this feature.
ACF Pro at $49/yr covers unlimited personal sites, which sounds good, but ACF Agency at $249/yr covers only 10 sites. For an agency managing 30 client sites, ACF costs $249/yr. For Field Forge, $169/yr.
For a single site, ACF is $49/yr vs Field Forge at $35/yr.
In October 2024, a dispute between WP Engine and WordPress.org over ACF branding and control led to WordPress.org forking ACF into a new plugin called Secure Custom Fields (SCF). SCF is now installed automatically when users search for ACF on wordpress.org. Many users are running SCF without realizing it’s no longer “the same ACF” they originally installed.
This created real confusion in the WordPress custom fields market:
Field Forge’s position: we don’t take sides in the ACF vs SCF dispute. Both are legitimate options. Field Forge is the clear third option — built from scratch, modern architecture, compatible with both via the ACF compat layer.
If you’re on ACF and want modern architecture + AI features + better pricing → switch to Field Forge. If you’re on SCF and want commercial support + AI features → switch to Field Forge. Either migration uses the same importer.
Read the full ACF vs SCF vs Field Forge guide →
Field Forge: 32 field types including all basic, choice, relational, layout, and pro compound fields.
ACF: ~30 field types in Pro, fewer in free.
Essentially equal. Both cover the same use cases.
Field Forge: modern three-panel drag-drop with keyboard shortcuts, inline editing, real-time preview, AI generation.
ACF: three-panel drag-drop builder with modal-based field creation.
Field Forge is more modern. Both functional, different generation of UI design.
Field Forge: custom table storage, batch loading, object cache integration. Benchmarked 3–10x faster on large sites.
ACF: wp_postmeta storage. N+1 queries on archives. No built-in batch loading.
Field Forge wins decisively on large sites. For small sites (<500 posts) the difference isn't noticeable.
Field Forge: verified one-click importer for ACF and SCF, with beta/manual mapping paths for Meta Box, CMB2, Carbon Fields, Pods, and Toolset until each source and extension set is tested.
ACF: no one-click migration from other plugins.
Field Forge wins for ACF/SCF migrations; other sources should be scoped as beta/manual.
Field Forge: AI schema generation (12 templates + AI fallback). AI field type suggestions.
ACF: none.
Field Forge wins.
Field Forge: TypeScript generation, GraphQL SDL, WPGraphQL auto-registration, REST API with field values inline.
ACF: WPGraphQL for ACF separate plugin, no TypeScript generation.
Field Forge wins.
Field Forge: full revision history with rollback.
ACF: none.
Field Forge wins.
ACF: thousands of plugins, themes, and tools built around ACF’s API.
Field Forge: growing ecosystem, but smaller. Compat layer means most ACF-aware plugins still work.
ACF wins for ecosystem. Field Forge’s compat layer mitigates the gap.
ACF: thousands of blog posts, YouTube videos, Stack Overflow answers.
Field Forge: growing but smaller.
ACF wins for learning resources. Much of what you’d learn about ACF applies to Field Forge via the compat layer.
ACF: WP Engine corporate backing, enterprise SLAs available.
Field Forge: priority support on paid plans, no enterprise contracts yet.
ACF wins for enterprise requirements. Field Forge is better for small and mid-market.
Migration takes 15–60 minutes for most sites.
Always backup before migration. Use your host’s backup tool or WP-CLI: wp db export backup.sql.
Install Field Forge alongside ACF. They don’t conflict because Field Forge’s compat layer only activates when ACF is deactivated.
Field Forge → Tools → Import from ACF. The tool reads ACF’s field groups and values, and copies them into Field Forge’s storage. Progress bar shows batches of 50 posts per request.
Field Forge runs automatic verification: count of migrated groups matches, count of migrated values matches, 10 random posts sampled and compared.
With both plugins still active, spot-check important pages: homepage, posts with custom fields, options pages, any custom post type. ACF still serves the data at this point (compat layer hasn’t activated yet).
Once verified, deactivate ACF. Field Forge’s compat layer takes over. Theme templates continue to render exactly the same way.
Spot-check the same pages from Step 5. If anything looks wrong, reactivate ACF (data is safe) and contact support.
To be fair, Field Forge isn’t the right choice for every site. ACF is better when:
For everything else — modern architecture, AI features, headless WordPress, agency use, performance-sensitive sites, and anyone who wants to save ~$80–$100/year — Field Forge is the better choice.
Will my ACF code still work after migration?
Yes. The ACF compatibility layer implements every ACF template function. get_field(), have_rows(), get_sub_field(), and acf_register_block_type() all work unchanged. Zero template rewrites.
Can I run ACF and Field Forge at the same time?
Yes, during migration. Long-term, one should be active at a time. Running both in production would mean two sets of field groups in two different storage backends.
Does Field Forge work with WPGraphQL for ACF?
Field Forge has its own native WPGraphQL integration (auto-registers types on activation). If you’re using WPGraphQL for ACF, you can uninstall it after migrating to Field Forge — the native integration replaces it.
What about my ACF JSON files from Local JSON?
Field Forge has its own Local JSON sync feature that reads similar JSON files from a theme directory. ACF JSON files can be imported into Field Forge with minor format adjustments (our migration tool handles this automatically).
Is migration reversible?
Yes. Field Forge’s migration is non-destructive — ACF’s data stays in place during and after migration. If you deactivate Field Forge, your site falls back to ACF (if still installed) with all data intact.
What about ACF Extended, ACF Frontend, and other ACF add-ons?
Field Forge covers most features from popular ACF add-ons natively (additional field types, frontend form support via Form Forge). For niche add-ons that add specific functionality, reach out to support and we’ll advise on compatibility.
What’s the difference between ACF and SCF?
ACF is the original commercial plugin owned by WP Engine. SCF is the free WordPress.org fork created in October 2024. They share the same data format and template function API, so Field Forge’s migration and compatibility layer work for both. Complete ACF vs SCF vs Field Forge guide →
