A side-by-side editorial comparison of Buttondown and Kit (formerly ConvertKit) — release velocity, themes, recent moves, and the top alternatives to consider.
Buttondown vs Kit (formerly ConvertKit): at a glance
What is Buttondown?
Buttondown gives publishers granular AI-crawler controls as daily fixes continue
Buttondown ships multiple small updates daily across subscription portal reliability, email client rendering, automation tooling, and comment moderation. The subscription-facing infrastructure — paused subscriptions, reactivation flows, upgrade prompts — has been the primary bug-fix target. The automation engine's action cap moved from 25 to 100, and comment moderation gained author-banning shortcuts.
What is Kit (formerly ConvertKit)?
Kit handed page-building to an agent, then went back to cleaning up the subscribers list
The Kit MCP crossing from reading a creator's list to building and editing landing pages remains the defining recent release. Since then the work has been ordinary interface repair on the subscriber surface: the Subscribers page was reorganised around search and filtering, and bulk actions became a floating menu that follows the scroll instead of sitting at the top of the list. Creator Network connection requests and custom favicons round out the window.

Buttondown gives publishers granular AI-crawler controls as daily fixes continue
◆ Current state
Buttondown ships multiple small updates daily across subscription portal reliability, email client rendering, automation tooling, and comment moderation. The subscription-facing infrastructure — paused subscriptions, reactivation flows, upgrade prompts — has been the primary bug-fix target. The automation engine's action cap moved from 25 to 100, and comment moderation gained author-banning shortcuts.
◆ Where it's heading
The Sep 12 Crawling add-on is the most directional recent move: three separate toggles (search engines, AI crawlers, everything else) replacing a simpler noindex system. That directly addresses the AI training-data debate and positions Buttondown as a tool for publishers who want fine-grained control over their archives. Bluesky card rendering points the same direction — tighter integration with creator-native platforms.
◆ Prediction
Buttondown will extend its automation engine further and add more platform integrations. More granular content licensing or distribution controls are plausible next steps given the strong directional signal from the AI crawler controls.

Kit handed page-building to an agent, then went back to cleaning up the subscribers list
◆ Current state
The Kit MCP crossing from reading a creator's list to building and editing landing pages remains the defining recent release. Since then the work has been ordinary interface repair on the subscriber surface: the Subscribers page was reorganised around search and filtering, and bulk actions became a floating menu that follows the scroll instead of sitting at the top of the list. Creator Network connection requests and custom favicons round out the window.
◆ Where it's heading
The Kit MCP is the axis, and it has already made its jump — from read-and-analyze in May to producing the published artifact in July. What follows is consolidation: the manual surfaces are being tidied so the things an agent can do and the things a creator does by hand sit on comparable footing. Nothing in this window extends the MCP itself, which makes the current period a pause rather than a redirection.
◆ Prediction
Expect the MCP surface to extend to more of the artifacts Kit publishes now that landing pages have proven the pattern. The subscriber-page work reads as a finished cleanup rather than the start of a larger rebuild.
