Zernio vs Ayrshare
Zernio is an API for 16 social platforms plus ads, an inbox, SMS and WhatsApp. Ayrshare is a posting API for 14 networks billed per social profile. We make a third option, yeetpost, so we list it in the last column and say where it is narrower.

| Image cards | Not mentioned on the pages we read. | Not mentioned on the pages we read. | draw_card writes an image card for a post itself, in the connection's saved look: your colors, fonts and logo, with the post's own numbers on it (POST /posts/{postId}/card). render_image is the path where the agent writes the HTML. |
#Which one to pick
Zernio suits you if you need a platform we do not have, or ads, an inbox, SMS or WhatsApp in the same API.
Ayrshare suits you if you build a SaaS or agency product on many end customers, and a profile holding all 14 networks suits how you bill.
yeetpost suits you if an agent runs a brand on LinkedIn, X, Bluesky, Discord, Telegram or Mastodon and you want a saved voice, image cards drawn from a saved look and queues behind a hosted MCP server. It is narrower than both of the others on platforms, and we say so in the table.
