Zernio (formerly Late) alternative: pay per business, get each post written
Zernio — Late until its rebrand — is a developer-first API with SDKs in eight languages and messaging and ads on top. It prices per connected account, which gets expensive when one business is on five networks. PostWire prices per business and writes each network's post for you.
Short answer. For an agency with 10 clients on 5 networks, Zernio's per-account pricing comes to $168 a month; PostWire's is $29. If you need its SDKs, X, WhatsApp, SMS or ads APIs, Zernio does far more than PostWire.
Every Zernio price and feature here was read on Zernio's own pages on Sept 26, 2026, with the link next to it. If they changed since, their page wins.

| Refund or guarantee | 14 days on paid plans | No refunds (usage-based billing) |
What Zernio does better
- Developer tooling: SDKs in eight languages and a CLI. PostWire has a REST API with an OpenAPI spec and no SDK.
- More than social posting: WhatsApp, SMS, phone numbers and ads APIs. PostWire only writes and publishes posts.
- More networks, including X, Reddit and LinkedIn company Pages. PostWire has none of those yet.
- Verified n8n nodes, plus Make and Zapier. PostWire's n8n node is not verified yet and there is no Zapier app.
When to pick which
Pick Zernio if…
- You're a developer who wants typed SDKs, a CLI and white-label OAuth for your own users.
- You need X, Reddit, WhatsApp, SMS or ads from the same vendor.
- You connect only a few accounts, where the first two free and $6 each stay cheap.
Pick PostWire if…
- Each business is on several networks, so per-account pricing multiplies: 10 businesses × 5 networks is $29 here.
- You want each network's post written from one idea instead of writing five versions yourself.
- You want TikTok and Meta through apps that are already approved, with no app review on your side.
10 businesses on 5 networks each: the monthly bill
An agency or a freelancer with ten clients, each on five networks, about 20 posts per client a month. That is 50 connected accounts, which is where the pricing unit decides the bill.
| Tool | How it's counted | Per month |
|---|---|---|
| PostWire Pro | 10 businesses fit in Pro (10 businesses, 2,000 posts a month; 10 × 20 posts × 5 networks = 1,000) | $29 |
| Zernio (per account) | 50 accounts: first 2 free, then 8 × $6 + 40 × $3 | $168 |
Monthly billing in USD, before tax. Source: zernio.com/pricing.md, read on Sept 26, 2026; PostWire's prices come from the code that bills you.
What “a different post per network” means
Zernio publishes the text you send it. PostWire writes each network's version first — a hook for TikTok, a searchable title and tags for YouTube, a longer first-person post for LinkedIn — and then publishes them.
