Alternatives
Free and open-source social media tools, compared honestly
If you want a free or self-hosted way to plan social media, you have real options. Here is a fair look at where each one fits, including where pendpost is not the right pick. The short version: for a broad dashboard across many platforms, look at Postiz or Mixpost; for an AI agent that drafts and schedules while you approve, that is what pendpost is for.
| Tool | License | Free to run | Self-host | Local-first | AI agent / MCP | Approval gate |
|---|---|---|---|---|---|---|
| pendpost | MIT | Free | Yes (local-first, always-on on a server) | Yes (127.0.0.1) | MCP-native | Yes, fail-closed |
| Postiz | AGPL-3.0 | Free self-host; paid cloud | Yes, or cloud | No (server/cloud app) | Yes (MCP server) | No built-in approve step |
| Mixpost | Open core + paid Pro | Free (Lite); paid Pro | Yes | No (self-hosted server) | Yes (Pro) | Team approvals (Pro) |
| Buffer | Proprietary | Free plan with limits | No | No (hosted SaaS) | Yes (hosted MCP server) | Team plan |
| Hootsuite | Proprietary | Paid (free trial) | No | No (hosted SaaS) | Yes (hosted MCP servers) | Advanced and Enterprise plans |
| Metricool | Proprietary | Free plan with limits | No | No (hosted SaaS) | Yes (hosted MCP server) | Advanced and Custom plans |

When each one wins
Postiz is the strongest pick if you want one dashboard that reaches a very wide set of platforms, with the option of a hosted plan if you would rather not self-host. It also ships an MCP server. It is AGPL-3.0, which is worth knowing if you intend to embed or modify it inside a closed product.
Mixpost suits a team that wants a self-hosted, Buffer-style dashboard and is happy on a paid Pro tier for the advanced features.
Buffer and Hootsuite are the right answer when you want a polished, hosted product with nothing to install. They hold your accounts and your data, and you pay for the convenience. Buffer has a free plan; Hootsuite offers a trial.
Metricool is the pick when analytics lead: competitor tracking, ads reporting and client reports, with scheduling built in and a free plan.
Every tool here now ships an MCP server (Mixpost in its Pro edition), so an AI agent can drive any of them. What differs is where the agent's posts land. In the tools we checked, an agent can schedule posts directly, and an approval step, where one exists, sits on a paid plan.
pendpost wins on a narrower axis: you want an AI agent to do the drafting and scheduling, you want a human to approve before anything publishes, and you want it all running on your own machine under a permissive MIT license. It is MCP-native, local-first (binds 127.0.0.1, nothing phones home), and adds anti-ban circuit breakers and a caption brand-lint. It does not try to match the platform breadth of a big dashboard, and it is young.
