Zernio vs Blotato: the facts side by side, and a third option

Both are APIs that publish to several social networks. Here is what each one bills, what it costs for an agency, its free plan, MCP server and refund — each cell read on the vendor's own page, with the link and the date — next to PostWire, which also writes each network's post.

Short answer. For 10 clients on 5 networks: Zernio $168 — per account, Blotato $499 — Agency, PostWire $29 (Pro). PostWire is priced per business, has a free plan with the API and the MCP server, and writes a native post for each network from one idea.

Where PostWire is ahead

  • The lowest bill of the three for an agency. 10 clients on 5 networks: $29 a month on PostWire Pro, every network included. Zernio: $168; Blotato: $499.
  • Per business, not per account. 10 businesses on 5 networks are $29 a month, and a sixth network costs nothing. Zernio bills each connected account — first 2 free, then $6, $3 and $1 each — so the same 50 accounts are $168.
  • A free plan with the API and MCP in it. 1 business, 20 posts a month, no card, no time limit. Blotato has no free plan, and its 7-day trial excludes the API: generating a key ends the trial and starts the paid Starter.
  • It writes the posts. One request returns a native version for each network from one idea. On Zernio you send the text for each post.
  • Every network's post written automatically, from one idea, in one request — from the dashboard, REST, n8n or MCP. On Blotato you ask its chat for each rewrite.
  • A 14-day refund on every paid plan. Zernio's usage-based billing has no refunds.
  • An image or a short video from your words, with no credits. "Make an image from this post" and "Make a video from this post" turn the caption into an image card (1080×1350 or 1080×1920) or an 8–12 s vertical video, on every plan. Blotato's visuals and video spend AI credits (1,250 a month on Starter).
