Kit (formerly ConvertKit) vs Postiz: at a glance
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.
What is Postiz?
Postiz encrypts channel tokens and lets agents send connect links for new channels.
Postiz's November 13 release encrypts channels' access and refresh tokens in the database when enabled, with a local key or AWS KMS, and needs no migration. A new connect link endpoint and MCP tool let an app or agent give someone a one-hour link that adds their social channel to a workspace. It also fixes two access-control holes (billing routes open to plain members, and post saves across organizations), adds Amazon SES for email, and fixes 40+ provider and billing issues.

◆ 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.
Postiz
2.5MKT AUTO
Postiz encrypts channel tokens and lets agents send connect links for new channels.
◆ Current state
Postiz's November 13 release encrypts channels' access and refresh tokens in the database when enabled, with a local key or AWS KMS, and needs no migration. A new connect link endpoint and MCP tool let an app or agent give someone a one-hour link that adds their social channel to a workspace. It also fixes two access-control holes (billing routes open to plain members, and post saves across organizations), adds Amazon SES for email, and fixes 40+ provider and billing issues.
◆ Where it's heading
Postiz still ships large releases about every six weeks. The last three have moved it from a scheduler toward publishing infrastructure that other software and agents can drive, with MCP access, preview comments and now connect links. This release adds the security work, encrypted tokens and tenant isolation, that larger self-hosted and multi-organization deployments need.
◆ Prediction
The next release will likely extend connect links to platforms that need API keys or instance URLs, and keep tokens out of Temporal history, which this release describes as groundwork.
