Embed SDK, API, MCP Server & CLI

Add AI carousel creation to any app with our SDK, API, MCP server or CLI

Four ways to plug PostNitro's design engine into your stack: embed our freeform editor in your app, automate design and scheduling over REST, let AI assistants work conversationally via MCP, or script everything from the terminal with the CLI. Same API key, same credits — pick the interface that fits.

Embed SDK — a carousel editor inside your app

Drop PostNitro's full visual editor into your platform so your users can create and edit on-brand carousels without ever leaving your product.

Don't Just Create Posts — Schedule Them Too

Designing the post is only half the job, so PostNitro now finishes it: schedule posts or save drafts directly to LinkedIn, Instagram, TikTok, Threads, and Facebook, with per-platform captions and settings. Generate or import a design, attach it to a time slot, and PostNitro publishes it for you — from the API, the MCP server, or the CLI, with no separate scheduling tool.
