Posting the same thing to six networks by hand is an hour a day nobody has

Scheduling posts across networks is a mature category and Rutba Social does the expected things: one composer for X, Facebook, Instagram, LinkedIn, TikTok and YouTube, a calendar with per-network preview, approvals before anything goes live, per-account connection management, and delivery reporting per network.

If that is all you need, plenty of products will do it and several have been doing it for a decade. The reason to read further is the second half.

The API is the same one the console uses

The Publish API is not an export hatch bolted onto a finished product. It is the documented HTTP API and SDK the console itself is built on, which is a meaningful difference: an API built alongside a product tends to lag it, because the team ships the feature to the interface and gets to the endpoint later.

An API the interface consumes cannot lag. If the console can do it, the endpoint exists, because that is how the console does it.

An API the product does not use is a promise. An API the product is built on is a fact.

And the same surface as agent tools

The third application exposes that publishing surface as Model Context Protocol tools, so an assistant can draft and schedule with the same permissions a person has.

The phrase to notice is "the same permissions". The tools do not run as a superuser with an API key that can post anywhere. They are bound to what the person operating them is allowed to do, and the approval step still applies, which is the difference between letting an assistant help and letting it publish.

The one product with its own sign-up

Priced per brand, not per seat

Per-seat pricing on a social tool taxes the approval step: the person who signs off posts once a week costs the same as the person writing them all day, so teams share a login and the audit trail stops meaning anything.
