A side-by-side editorial comparison of Formidable Forms and Keila — release velocity, themes, recent moves, and the top alternatives to consider.
Formidable Forms vs Keila: at a glance
What is Formidable Forms?
Formidable Forms keeps handing MCP tools to each add-on, now Landing Pages.
Landing Pages v1.0.04 adds MCP support, so AI clients can list, create, update and delete landing pages, and fixes pages loading when the setting is disabled. It follows the October 14 wave: core v7.0 with spam entries and shortcode hardening, and MCP tools in Visual Views and Coupons. A day earlier the Forms API add-on let plugins ship their own MCP support.
What is Keila?
Keila v0.30.3 adds Liquid template caching for measurably faster campaign renders on large lists.
Keila is a steady open-source email newsletter platform built on Elixir/Phoenix, shipping incremental quality improvements. v0.30.3 (the most recent release) adds campaign ID as a template variable, introduces TLS/STARTTLS and SMTP authentication environment variables for system mailer configuration, adds Liquid template caching (described as a significant render performance improvement for large campaigns), and accelerates several queries across large projects.

Formidable Forms
5.0MKT AUTO
Formidable Forms keeps handing MCP tools to each add-on, now Landing Pages.
◆ Current state
Landing Pages v1.0.04 adds MCP support, so AI clients can list, create, update and delete landing pages, and fixes pages loading when the setting is disabled. It follows the October 14 wave: core v7.0 with spam entries and shortcode hardening, and MCP tools in Visual Views and Coupons. A day earlier the Forms API add-on let plugins ship their own MCP support.
◆ Where it's heading
MCP support is moving into each add-on rather than living in a central API layer, so the whole suite becomes operable by AI clients piece by piece. Spam handling is becoming a first-class entry state that add-ons respect. September's work on drafts, abandonment and Stripe points the same way: more forms completed, cleaner data.
◆ Prediction
Expect Stripe and Conversational Forms to get their own MCP tools next, and follow-up patches for 7.0's security changes.
Keila
2.5MKT AUTO
Keila v0.30.3 adds Liquid template caching for measurably faster campaign renders on large lists.
◆ Current state
Keila is a steady open-source email newsletter platform built on Elixir/Phoenix, shipping incremental quality improvements. v0.30.3 (the most recent release) adds campaign ID as a template variable, introduces TLS/STARTTLS and SMTP authentication environment variables for system mailer configuration, adds Liquid template caching (described as a significant render performance improvement for large campaigns), and accelerates several queries across large projects.
◆ Where it's heading
Keila's recent releases — v0.30.0's transactional email API, v0.20.0's new email scheduler, and now v0.30.3's performance work — show a project that is consolidating its architecture before broadening its feature set. The self-hosting focus remains; the additions to system mailer configurability suggest the project is listening to operators running Keila in production with non-standard SMTP setups.
◆ Prediction
Transactional email capabilities from v0.30.0 will likely expand — more API endpoints, webhook delivery events, or better unsubscribe handling for transactional vs. campaign messages. Performance tooling for large lists will continue as the Liquid caching work surfaces the right optimization targets.
