Auto-split into a thread for X & Bluesky · posted as one update on LinkedIn.
Built for individuals and teams alike
Composer
Draft with media and alt text, watch a live character count per network, and auto-split long posts into threads 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.
Analytics
Follower and post-count trends per account, plus per-post engagement: likes, reposts, replies, and impressions.
Connected accounts
Connect X, LinkedIn, Bluesky, and Discord via OAuth or app password, group accounts into reusable sets, and get nudged when one needs reconnecting.
Workspaces & team
Multiple workspaces with role-based memberships, email invitations, and ownership transfer. Every record is scoped to its workspace.
Notifications
In-app alerts the moment a post publishes or fails, or when an account needs your attention to keep posting.
Secure by default
Email/password with verification, two-factor (TOTP), passkeys (WebAuthn), and optional social login.
Drive it from your agent, or from your code
The interface is not the only way in. Every plan includes both, with no developer tier, no per-call fee, and nothing to apply for.
MCP server
Point any MCP client at your instance and it gets 22 tools to draft, schedule, and publish. Publishing, retrying, and deleting refuse to run without your explicit confirmation.
REST API
Two calls take you from a token to a published post. Bearer auth, JSON in and out, an OpenAPI spec, and one call fans a post out to every account you connected.
Your accounts,
locked down
Email and password with verification from the start, plus the modern factors you would expect. Shoutrrr encrypts account tokens at rest and never stores them in plain text.
Publish everywhere.
Own everything.
Start on managed Cloud in about a minute, or self-host the same open-source app on your own box. No per-seat pricing and no lock-in. Move between them whenever you want.
Answers in plain language
What platforms does Shoutrrr support?
Four networks today: X, LinkedIn, Bluesky, and Discord. Write once, adjust each post when needed, and schedule everything from one place. More networks are on the roadmap.
Can an AI agent post for me?
Yes. Every instance ships a Model Context Protocol server, so any MCP client can draft, schedule, and publish through 22 tools. It works with anything that speaks the protocol, not one named vendor. The server runs inside your own deployment, and publishing, retrying, and deleting all refuse to run without your explicit confirmation. There is also a full REST API. Every plan includes both, with no developer tier and no per-call fee.
Is Shoutrrr really free?
The open-source app is free forever under Apache 2.0. Self-host it with no paid seats or locked features. Managed Shoutrrr Cloud is $10/mo, which includes $5 of X usage, for teams who would rather not run it themselves.
Do I have to self-host?
No. Shoutrrr Cloud is live, so you can sign up and start posting in seconds. Self-hosting stays free and open source if you would rather run it yourself.
How do I install it?
To self-host, pull the prebuilt Docker image. It bundles the web app, queue worker, and scheduler in one container, and defaults to SQLite with no external services. Prefer zero setup? Skip it with Shoutrrr Cloud.
Should I pick Cloud or self-host?
Pick Cloud if you want zero ops. We run and update everything for a flat monthly fee. Pick self-host if you want full control of your infrastructure and data. It is free and open source. Same app either way. See the pricing section above for the details.
Can I use it with my team?
Yes. Invite teammates into shared workspaces with role-based access, and keep different brands, clients, or projects cleanly separated.
Is my data safe?
Shoutrrr is self-hosted, so your posts, accounts, and analytics stay on infrastructure you control. Account tokens are encrypted at rest.
How do I contribute?
Open an issue or pull request on GitHub. Bug reports, docs, and features all help. The whole project is Apache 2.0 licensed.
