Compare against
uplika vs zernio
zernio is the closest to us in shape: usage-based per connected account, free for the first two, and a hosted MCP server that accepts OAuth. It is also listed in the official MCP registry. Its own pages count its channels as 14, 15 and 16 in different places and its tool count as 280+ or 496, so we cite the documentation figure and note the disagreement rather than picking one.
What publishes today
Threads, Instagram, YouTube, Facebook, Bluesky, Telegram. Naver Blog publishes through the uplika Chrome extension in your own browser. TikTok is waiting on platform review: its real limits are listed so you can build against them now, and publishing there is refused rather than dropped quietly. We list fewer channels than the products below. If you need one we do not have, they cover more.
How they describe themselves
