WHY POSTZEN

Use PostZen when publishing is the infrastructure

PostZen works best when your product already owns content generation, user approvals, templates, and billing. The API handles account connection, media, and platform publishing.

No content-engine lock-in

Use your own prompts, CMS, agent, or editor before calling PostZen to publish.

Product-native accounts

Map each connected social account to your own users, teams, and workspaces.

Focused API surface

Start with connect, account lookup, media upload, and post creation instead of adopting a full creator stack.

WHICH ONE?

Choose based on the workflow you are building.

Choose PostZen if you:

  • You need publishing infrastructure inside your SaaS, agent, or internal tool.
  • Your app already owns the content editor, AI flow, or approval workflow.
  • You want connected-account pricing instead of a creator-tool subscription.
  • Your developers want a narrower REST publishing API.

Choose Blotato if you:

  • You want AI writing, video generation, image generation, and publishing in one workspace.
  • You use Blotato n8n, Make, MCP, or creator templates as the workflow center.
  • You want a creator/operator tool more than embedded publishing infrastructure.

Need the publishing API without the creator stack?

Choose PostZen when your product should own the content workflow and call a focused API for social account connection, media, and publishing.
