Act-On vs Formidable Forms
A side-by-side editorial comparison of Act-On and Formidable Forms — release velocity, themes, recent moves, and the top alternatives to consider.
Act-On vs Formidable Forms: at a glance
What is Act-On?
Marketing-blog feed crawled as a changelog — thought-leadership posts, no product releases.
The tracked feed is Act-On's marketing blog: posts on AI in marketing, deliverability policy changes, and vertical playbooks for manufacturing and financial services. These are content-marketing pieces, not product release notes. As product signal, they carry no information about what shipped in the platform.
What is Formidable Forms?
Formidable widens MCP compatibility and locks down signature files
Forms API v2.0.1 makes the Formidable MCP server tolerate the older MCP adapter versions bundled in other plugins such as WooCommerce and Rank Math, instead of refusing with an incompatibility message. Digital Signature Forms v3.2 adds form-level protection for signature files, a role requirement to access them, and permanent deletion of old signatures when an entry is deleted.

Act-On
2.5MKT AUTO
Marketing-blog feed crawled as a changelog — thought-leadership posts, no product releases.
◆ Current state
The tracked feed is Act-On's marketing blog: posts on AI in marketing, deliverability policy changes, and vertical playbooks for manufacturing and financial services. These are content-marketing pieces, not product release notes. As product signal, they carry no information about what shipped in the platform.
◆ Where it's heading
The feed will keep publishing SEO-oriented thought leadership, heavily weighted toward AI-in-marketing themes and industry verticals. No product-development trajectory is visible from this source.
◆ Prediction
Expect more blog posts on AI, lifecycle marketing, and vertical strategies. To track actual Act-On product changes, the crawl source needs pointing at a release-notes feed rather than the blog.

Formidable widens MCP compatibility and locks down signature files
◆ Current state
Forms API v2.0.1 makes the Formidable MCP server tolerate the older MCP adapter versions bundled in other plugins such as WooCommerce and Rank Math, instead of refusing with an incompatibility message. Digital Signature Forms v3.2 adds form-level protection for signature files, a role requirement to access them, and permanent deletion of old signatures when an entry is deleted.
◆ Where it's heading
Two threads are running in parallel across the add-on family. One is agent access, opened by the Forms API v2.0 MCP adapter and the WordPress Abilities API, now being made to coexist with the other plugins already shipping MCP adapters on the same site. The other is a sustained security pass, visible in signature file handling, tokenized CSV downloads, and the Stripe and core-plugin hardening earlier in the window.
◆ Prediction
Adapter-version collisions between plugins are likely to recur as more WordPress plugins ship MCP servers, so expect further compatibility patches rather than new API surface in the near term.
