Formidable Forms vs Keila: at a glance
What is Formidable Forms?
Formidable Forms 7.0.1 makes the builder preview reflect more Pro settings as they change.
Formidable Forms v7.0.1 extends the live builder preview to more Pro settings and warns admins when a hardened [frm-field-value] lookup is blocked. Same-day add-on patches fix REST-submitted signatures and inline calendars on multi-page forms. The week before, v7.0 hardened field-value shortcodes and several add-ons (Views, Coupons, Landing Pages) gained their own MCP tools.
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 7.0.1 makes the builder preview reflect more Pro settings as they change.
◆ Current state
Formidable Forms v7.0.1 extends the live builder preview to more Pro settings and warns admins when a hardened [frm-field-value] lookup is blocked. Same-day add-on patches fix REST-submitted signatures and inline calendars on multi-page forms. The week before, v7.0 hardened field-value shortcodes and several add-ons (Views, Coupons, Landing Pages) gained their own MCP tools.
◆ Where it's heading
Formidable is doing two things in parallel: exposing each add-on to AI clients through MCP, one at a time, and tightening data escaping in the core after 7.0. The 7.0.1 warning shows the hardening has user-facing side effects the team is now smoothing over.
◆ Prediction
Expect more add-ons to gain MCP management and further 7.0.x patches around blocked lookups.
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.
