yeetpost vs Zernio
Zernio is the closest thing to a competitor we have, and on some things they are ahead. Here is the whole table, including the rows we lose.
#Head to head
Their column is what their own public pages said on 29 August 2026: zernio.com/pricing, docs.zernio.com/mcp, docs.zernio.com/sdks and their homepage. Where we could not find an answer, the row says so rather than guessing.
| yeetpost | Zernio | |
|---|---|---|
| Platforms | 6: LinkedIn, X, Bluesky, Discord, Telegram, Mastodon. | 16 social platforms plus 7 ad networks. |
| Sandbox and test keys | Yes. A sandbox connection that validates and never publishes, and yp_test_ keys that cannot reach a live account. | None documented. Every integration test publishes for real. |
| Per-item results | One response carries a result per connection, so a partial failure is visible in the call that caused it. | One post object per request, polled for status. |
| Delivery log | A public webhook delivery log endpoint: every attempt, its status code and its response. | Not documented as a public endpoint. |
| Idempotency | Idempotency-Key. The same key replays the stored response verbatim, a different body on the same key is a 409, and errors are stored too. | x-request-id with a 5 minute retry window, plus a content-hash dedup that 409s identical content for 24 hours. |
| MCP tools | 5, all always visible. | 496, of which roughly 50 stay visible and the rest are found with search_tools. |
| CLI | Ten commands in the Node package, JSON on stdout by default, but that CLI ships in [email protected] and is not on npm yet. The published 1.x package posts with a single yeetpost <connection> <text> call. Use the MCP server or the REST API today. | @zernio/cli, 371 commands across 47 groups. JSON output by default. |
| SDKs | 2: Node and Python, hand written, zero dependencies. | 8: Node, Python, Go, Ruby, Java, PHP, .NET, Rust. |
| Multi-tenancy | Not yet. Profiles, connect URLs and profile-scoped keys are specced and on the roadmap. | Yes, and it is their strongest feature: profiles, hosted connect URLs, headless mode, scoped keys, an account.connected webhook. |
| Price per connected account | 2 free, then $5 (3-10), $2.50 (11-100), $1 (101+). | 2 free, then $6 (3-10), $3 (11-100), $1 (101+). |
| X posts | 2 cents a post, 25 cents when the text contains a link. | X's own rates passed through with no markup: $0.015 a post, $0.200 with a URL, $0.005 a read. |
| Support | In-app support threads, answered in the product, with email on reply. | A founder email address, plus Telegram, X, LinkedIn and GitHub. No SLA. |
The short version: they are wider, we are more exact. Six platforms that each pass a real post in CI before every deploy, per-connection results in the response that caused them, and a sandbox to develop against, against sixteen platforms, eight SDKs and a multi-tenancy model we do not have yet.
#What it costs
Both bills are graduated per connected account, and both charge separately for X, because X charges for the API. Move the sliders.
yeetpost
$62.80
per month
- Connected accounts
- $45.00
- X posts
- $17.80
Zernio
$68.10
per month
- Connected accounts
- $54.00
- X posts
- $14.10
yeetpost is $5.30 a month cheaper at these numbers, $63.60 a year.
Assumptions. Both ladders are graduated, so every account is billed at the rate of the band it falls in and the first two are free on both. yeetpost bills a flat 2 cents per X post and 25 cents when the text contains a link; Zernio passes X's rates through at $0.015 and $0.200. The link share applies only to the X posts you enter, rounded to the nearest post. Posts to every other platform are free on yeetpost and are not counted here for Zernio either. Reads and analytics, ad spend, phone numbers and WhatsApp are out of scope, and so is anything either of us charges in a currency conversion or a tax. The numbers come from our pricing page and from zernio.com/pricing as read on 29 August 2026. If theirs has moved since, theirs is the one to trust.
#Where Zernio is better
Four things, and none of them are close. Breadth: sixteen platforms against our six. If you need Instagram, TikTok, YouTube, Facebook or Pinterest today, we do not have them and no amount of API design makes up for that. Ads: they publish to seven ad networks and we do not touch ads at all. Analytics: they pull per-post metrics; we tell you a post went out and stop there. Multi-tenancy: profiles, hosted connect URLs, headless white-label connect and per-profile keys are a real product that we have specced and not built. If you are embedding posting inside your own SaaS for your own customers, they can do it now and we cannot.
They also have eight SDKs to our two, a longer changelog, and a status page fed by their own monitoring. We think our two SDKs are nicer to read. That is a taste argument, not a feature.
#Which one to pick
Pick Zernio if you need a platform we do not have, if you sell to your own customers and need tenant separation this quarter, or if ads and analytics are part of the job.
Pick yeetpost if you are wiring an agent or a deploy pipeline to the accounts we do support and you want the parts that make automation safe: five MCP tools an agent holds in context instead of 496 behind a search, a sandbox and test keys so CI never publishes by accident, a result per connection in the response that caused it, a delivery log for every webhook attempt, real Idempotency-Key semantics instead of a content hash that 409s a legitimate repeat post, and a cheaper first paid account.
