Alternatives
Postiz alternatives, compared honestly
Postiz is one of the strongest open-source social schedulers around, with a broad platform list, a big community and an MCP server. People look past it for a few reasons: the AGPL license, wanting an approval step before agent posts go live, or wanting something that runs on a laptop with no server to maintain. For a feature-by-feature look, see pendpost vs Postiz.
What does Postiz do well?
Breadth. Postiz lists 30+ channels, from X, LinkedIn, Instagram and TikTok to Reddit, Discord, Lemmy, Nostr and WordPress. You can self-host it free or pay for Postiz Cloud, which has a 7-day trial.
It is agent-friendly too. There is an official MCP server, on Postiz Cloud and on self-hosted installs, plus a public API. The project is very active on GitHub.
Why look for a Postiz alternative?
License first. Postiz is AGPL-3.0, which is fine for running it yourself and carries source obligations if you offer a modified version as a network service. Agencies that want to build on a scheduler inside a closed product often want MIT.
Then approvals. We could not find a built-in approve or reject step in Postiz, and a 2026 request for external approval links was closed as not planned. If an agent drafts your posts and a person should sign off on each one, that gap matters.
Last, where it runs. Self-hosted Postiz is a server app. Some people would rather run a tool on the laptop they already have, with nothing exposed to the internet.
Which Postiz alternatives are worth a look?
pendpost
MIT-licensed and local-first: it binds 127.0.0.1 and keeps your tokens in your own .env. Your agent drafts over MCP, and every post waits at a human approval gate by default.
Trade-off: Fewer platforms (11 live, 4 in beta), a smaller community, and a younger codebase.
Mixpost
A self-hosted team dashboard with approvals, analytics and an MCP server in its Pro edition.
Trade-off: The free Lite edition only publishes to Facebook Pages, X and Mastodon.
Buffer
Hosted scheduling with nothing to run, a free plan and an official MCP server.
Trade-off: Closed source and hosted only; approvals need the Team plan.
Metricool
Hosted scheduling with much deeper analytics and ads reporting.
Trade-off: Closed source, and the free plan leaves out LinkedIn and X.
How does pendpost compare to Postiz?
| Postiz | pendpost | |
|---|---|---|
| Where it runs | A server app you host, or Postiz Cloud | Your machine (binds 127.0.0.1) or your own server |
| License | AGPL-3.0 | MIT |
| AI agent access | MCP server and public API | MCP-native; an agent can never approve its own post |
| Approval before publishing | No built-in approve step found | On by default |
| Platforms | 30+ (vendor figure) | 11 live, 4 in beta |
| Maturity | Mature, large community | Young, with rough edges |
If breadth and polish matter most today, Postiz is the safer pick, and we are happy to say so on our own site.

Mixpost or Postiz: which should I use?
Postiz covers far more platforms in its free, open-source version.
