Introduction

Shoutrrr is the open-source, self-hostable alternative to Buffer, Typefully & Hootsuite — write once, publish everywhere.

Shoutrrr is a social media scheduling tool you run yourself. Connect your accounts, draft a post once, and send it to every network at the same time — or queue it to go out on a recurring schedule. No monthly seat fees, and no third party holding your tokens or your data.

It’s built for individuals and teams: invite collaborators into a shared workspace, keep clients or brands separated, and see how your posts perform — all from a single, fast interface.

Why Shoutrrr

  • You own everything — your posts, your audience tokens, your analytics, all on your own infrastructure.
  • One post, every platform — compose once and publish to multiple accounts, tweaking the text per network when you want.
  • Plan ahead — a posting queue with recurring time slots and a month calendar keep your feed consistent without babysitting it.
  • Made for teams — workspaces, roles, and email invites keep clients and collaborators tidy.
  • No lock-in — open source under Apache 2.0, runs anywhere Docker does.

When a post is too long for a platform that supports threads, Shoutrrr splits it into a thread automatically. Each target publishes independently and retries on failure.

Core features

  • Composer — draft with media and alt text, with a live per-network character count.
  • Multi-account publishing — fan one post out to many accounts at once, with optional per-platform overrides.
  • Queue & calendar — recurring posting slots in your workspace’s timezone, plus a month calendar to review everything. Publish instantly whenever you like.
  • Analytics — follower and post-count trends per account, plus per-post engagement (likes, reposts, replies, impressions).
  • Workspaces & team — multiple workspaces with role-based memberships, email invitations, and ownership transfer.
  • Secure by default — email/password with verification, two-factor (TOTP), passkeys (WebAuthn), and optional social login. Account tokens are stored encrypted and refreshed automatically.
  • AI-ready — a built-in MCP server lets assistants draft, schedule, and (with your confirmation) publish, scoped to a single workspace.
