Compare against
uplika vs Postiz
Postiz is the only one here you can run yourself. It is AGPL-3.0 and the project states there is currently no feature difference between the hosted and self-hosted versions, though the cloud plans cap connected channels and self-hosting does not. Its MCP server exposes nine tools and offers both an API key endpoint and an OAuth one.
What publishes today
Threads. The other channels are listed with their real limits so you can build against them now, but they are waiting on platform review and publishing to one is refused rather than dropped quietly. If you need a channel live this week, the products below cover more surface than we do today.
