Key Features

When teams plan content across multiple networks, Shoutrrr helps you draft once and publish across accounts, with live per-network counts and threading:

Composer

Draft with media and alt text, watch a live character count per network, and auto-thread long posts where supported

Multi-account publishing

Fan one post out to many accounts at once with optional per-platform overrides. Each target publishes independently and retries on failure

MCP & REST API

Point any MCP client at your own instance and it gets 22 tools to draft, schedule, and publish. Publishing always needs your confirmation. The same actions work over REST when you would rather write code

Queue & calendar

Set recurring posting slots in your timezone, drop drafts into the queue, and review everything on a month calendar. Publish instantly anytime

Summary

Best for individuals and teams—content creators, marketing teams, and ops groups coordinating multi-network campaigns.
