Publish Now vs Zernio
Zernio meters every social account you OAuth in. At 50 accounts that's about $168/mo, and their unlimited-posts tier still caps how many accounts you can connect. Publish Now is $5/mo plus credits. Accounts are free. You pay for the posts you actually ship.

TL;DR
Zernio charges per connected account. At 50 accounts you're paying ~$168/mo and they cap your unlimited posts. Publish Now charges $5/mo + credits. Accounts are free, you pay for what you actually do.

}'The reasons people search
Per-account pricing is a tax that scales with every customer you onboard, not with the value you deliver
The $49/mo tier markets unlimited posts but still caps the number of accounts you can connect, which is a weird tradeoff to explain to your team
Multi-tenant SaaS math turns ugly fast when every end-user account is a billable line item on your invoice
Engagement automation (comments, DMs, follows) isn't on the roadmap, so the per-account meter is the whole product
The 99.97% uptime claim is a vendor number, not a public incident history you can audit
Pricing model: Per connected account
Cost at 5 accounts: ~$19/mo (Starter, 120 posts/mo cap)
Cost at 10 accounts: ~$49/mo (Unlimited posts tier)
Cost at 20 accounts: ~$78/mo
Cost at 50 accounts: ~$168/mo
Pricing model: Flat $5/mo + credits
Cost at 5 accounts: $5/mo + credits
Cost at 10 accounts: $5/mo + credits
Cost at 20 accounts: $5/mo + credits
Cost at 50 accounts: $5/mo + credits
Zernio covers 15 platforms in one API (we ship 3), publishes a 99.97% uptime claim, and ships a clean MCP server for AI agents.

| MCP server (AI agents) | Yes | Yes |
| Table stakes in 2026, not a differentiator. | ||
| Account caps | Yes, even on the unlimited-posts tier | None |

The shape of the product, not just the pitch.
Zernio meters every social account you OAuth in. Publish Now is $5/mo plus credits, and connected accounts are not a billable axis. Connect 5 accounts or 500. The bill follows the work you ship, not the OAuth tokens you store.
Zernio's $49/mo tier markets unlimited posts but still caps how many accounts you connect. Publish Now does not cap accounts. The variable your product needs to scale freely is usually account count, not post count.
Onboarding the 50th customer should not move your COGS line item. Publish Now is built so the bill stays decoupled from end-user account count, with per-tenant credit isolation and rate-limit handling designed for that workload.
Posting is the first job. Comments, DMs, follows, and likes are next, on the same JSON shape and the same credit pool. Zernio is a posting API; Publish Now is the platform engagement runs through.
Queues, retries, calendar primitives, and per-tenant rate budgets are built in. The same payload that posts now also posts later. Scheduling is not bolted on as an afterthought.
Post to X, Instagram, and YouTube with one payload. Per-platform overrides live on the same body, not separate API calls. Your product code stays small as you add platforms.
Run the same scale-up against both and you stop second-guessing the bill.
| Scale | Zernio | Publish Now | Delta |
|---|---|---|---|
| 5 accounts | ~$19/mo (Starter, 120 posts/mo) | $5/mo + credits | Flat from here to 500 accounts |
| 10 accounts | ~$49/mo (Unlimited tier, accounts still capped) | $5/mo + credits | - |
| 20 accounts | ~$78/mo | $5/mo + credits | - |
| 50 accounts | ~$168/mo | $5/mo + credits | The number to fixate on |
| 100 accounts | ~$300+/mo (linear extrapolation) | $5/mo + credits | - |
You need one of Zernio's 15 platforms today that Publish Now does not yet ship. We cover X, Instagram, and YouTube. Check our platform list before assuming.
You're comfortable trusting their published 99.97% uptime number as a vendor claim, without a public incident history you can audit.
You're posting fewer than 120 posts per month from a small, fixed account count where the per-account math never compounds against you.
You expect to pass 20 connected accounts. That's where Zernio's per-account meter starts shaping your unit economics, and Publish Now's flat $5/mo doesn't.
You want a flat bill you can put in your own pricing-page math. Onboarding more end-user accounts should not move your COGS line item.
You don't want the unlimited-posts-but-capped-accounts tradeoff. The variable you need to scale freely is account count, not post count.
Switching from Zernio
Swapping from Zernio is a low-risk, math-on-your-side move. The OAuth flow is similar, the JSON shape concept is similar, and the per-account meter goes away.
