Buttondown vs Formidable Forms: at a glance
What is Buttondown?
Buttondown closes an API send loophole and blocks confirmation-email floods in its daily fixes.
Buttondown is a newsletter platform run on a daily-changelog cadence of small fixes. Over the last week it added sign-in limits, two-factor lockouts and auto-disabled failing webhooks, then closed a gap where API keys without sending access could still send through POST /v1/emails. It also stopped bots from signing one inbox up to many newsletters at once, and raised text contrast in light and dark mode.
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.

Buttondown
5.0MKT AUTO
Buttondown closes an API send loophole and blocks confirmation-email floods in its daily fixes.
◆ Current state
Buttondown is a newsletter platform run on a daily-changelog cadence of small fixes. Over the last week it added sign-in limits, two-factor lockouts and auto-disabled failing webhooks, then closed a gap where API keys without sending access could still send through POST /v1/emails. It also stopped bots from signing one inbox up to many newsletters at once, and raised text contrast in light and dark mode.
◆ Where it's heading
The daily polish is running on two tracks: account and API security (rate limits, 2FA lockout, API key permissions, abuse protection) and accessibility (screen-reader support, keyboard navigation, now contrast). Both point at a product being hardened for larger and more compliance-sensitive senders, not at new features.
◆ Prediction
Expect more permission and abuse fixes alongside further accessibility passes, still shipped as daily batches of small fixes.
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.
