#Honest table
Zernio's column is what their own public pages said on 2026-10-29: zernio.com/pricing, docs.zernio.com/quickstart. Where we could not find an answer, the cell says so rather than guessing. If their site has moved since, theirs is the one to trust.

| Price | Per connected account per month: 2 free, then $5 (3 to 10), $2.50 (11 to 100), $1 (101 and up). Posts are unlimited.

| Brand voice | Saved on each connection with set_voice. The agent reads it with get_brand before it writes, so posts come out on brand without a new brief. | Not mentioned on the pages we read. |
| Image cards | 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. | Not mentioned on the pages we read. |
| Queues | Posting slots per connection, with a timezone. A post with queue takes the next open slot. | Unlimited posts, threads, first comment, queue and calendar on every account. |
| Agencies and end customers | Profiles, one per end customer, with hosted connect URLs and API keys scoped to one profile. | Profiles, hosted connect URLs, headless mode and scoped keys. |
#Who should switch, and who should stay
Stay on Zernio if you need a platform yeetpost does not have live yet. Platforms: 16 against our 6, plus 8 ad networks. Inbox and messaging: DMs, comments, reviews, SMS and WhatsApp. Eight published SDKs and a much larger docs and changelog surface.
Switch to yeetpost if your accounts are on LinkedIn, X, Bluesky, Discord, Telegram or Mastodon, an agent writes the posts, and you want them on brand with a card drawn from the brand's own look. The price also drops when the accounts are few: one brand on all six live platforms is 6 connected accounts, 2 free and 4 at $5, so $20 a month. X posts are billed on top at X's own rates.
#Migrating
A single post, before and after. Create a key on the API page and connect each account once in the dashboard; you then post by connection slug.
Zernio
curl -X POST https://zernio.com/api/v1/posts \
-H "Authorization: Bearer $ZERNIO_API_KEY" \
-H "Content-Type: application/json" \
-d '{"content": "Hello world", "scheduledFor": "2026-12-01T10:00:00",
"platforms": [{"platform": "linkedin", "accountId": "ACCOUNT_ID"}]}'yeetpost
curl -X POST https://api.yeetpost.com/api/v2/posts \
-H "x-api-key: $YEETPOST_API_KEY" \
-H "content-type: application/json" \
-d '{"text": "Hello world", "scheduledFor": "2026-12-01T10:00:00",
"timezone": "Europe/Helsinki", "connectionSlugs": ["linkedin"]}'- content becomes text, and the platforms array of platform and accountId pairs becomes connectionSlugs. You post to a connection by its slug, not by an account _id.
- A scheduledFor without an offset is read in the timezone you send alongside it, as on Zernio.
- Ads, the inbox, SMS, WhatsApp and every platform outside our six have no equivalent here yet.
#What yeetpost does differently
The difference we care about most is not an endpoint. It is what happens when an agent runs a brand's social for a month. The voice and look live on the connection, so the agent does not have to be told again, and an image card is drawn by draw_card in the brand's own look instead of a stock picture. The whole thing sits behind a hosted MCP server with 37 tools that an agent signs in to with OAuth. We did not find a voice saved per connection or HTML image cards on Zernio's pricing or MCP pages.
Below is the same Herizon post sent as plain text and sent with the card the agent rendered. The card is a real one, drawn from the look saved on the connection.
Seven events at Herizon this week, 26 Oct to 1 Nov. Co-work session on Monday at 10:00, the Finnish for work conversation circle on Tuesday at Oodi, mentor meetup on Thursday and a CV clinic on Friday. Everything is listed at portal.herizon.io.
