Formidable Forms vs Kit (formerly ConvertKit)
A side-by-side editorial comparison of Formidable Forms and Kit (formerly ConvertKit) — release velocity, themes, recent moves, and the top alternatives to consider.
Formidable Forms vs Kit (formerly ConvertKit): at a glance
What is Formidable Forms?
WordPress form builder ships a steady security-and-refinement cadence.
Formidable Forms is a WordPress form and data-views plugin shipping frequent point releases across its core and add-ons. The current batch is weighted toward security hardening (access validation, SVG sanitization, secure download tokens) alongside incremental builder and views improvements.
What is Kit (formerly ConvertKit)?
Kit rebuilds its creator stack and wires in AI, from MCP to subscriber intelligence
Kit (formerly ConvertKit) is modernizing its core creator tooling — a rebuilt landing-page editor, redesigned navigation, custom favicons — while opening two AI-flavored fronts: an MCP server that lets AI assistants operate the account, and Subscriber Signals for audience enrichment. Renaming 'Creator profile' to 'Newsletter site' signals a tighter focus on the newsletter as the hub.
Formidable Forms vs Kit (formerly ConvertKit): editorial side-by-side
Formidable Forms
5.0MKT AUTO
WordPress form builder ships a steady security-and-refinement cadence.
◆ Current state
Formidable Forms is a WordPress form and data-views plugin shipping frequent point releases across its core and add-ons. The current batch is weighted toward security hardening (access validation, SVG sanitization, secure download tokens) alongside incremental builder and views improvements.
◆ Where it's heading
The product is in a maturity-and-hardening phase: locking down data access and file handling while extending views, styling, and payment integrations. Add-ons are versioned independently but move in lockstep with core releases.
◆ Prediction
Expect continued security tightening around uploads and data access, plus incremental expansion of the Views and Landing Pages surfaces introduced recently.
Kit (formerly ConvertKit)
5.0MKT AUTO
Kit rebuilds its creator stack and wires in AI, from MCP to subscriber intelligence
◆ Current state
Kit (formerly ConvertKit) is modernizing its core creator tooling — a rebuilt landing-page editor, redesigned navigation, custom favicons — while opening two AI-flavored fronts: an MCP server that lets AI assistants operate the account, and Subscriber Signals for audience enrichment. Renaming 'Creator profile' to 'Newsletter site' signals a tighter focus on the newsletter as the hub.
◆ Where it's heading
The product is converging on an all-in-one creator platform that no longer needs a third-party page builder, plus a data-and-agent layer on top of the subscriber list. Expect Subscriber Signals and Kit MCP to move from beta and early access toward general availability, and more of the UI to be rebuilt in the new editor's style.
◆ Prediction
Kit will likely graduate MCP and Subscriber Signals out of beta and keep replacing legacy editors with the new landing-page framework.
