UniPost vs Zernio — Embedded publishing without the connected-account tax

Zernio's public pricing is pay per connected social account. UniPost self-serve plans are based on product tier and monthly post capacity, so embedded apps with many low-volume users can avoid account-meter pricing.

TL;DR — Which should you choose?

Choose UniPost if:

You are building an app where your own users connect social accounts

You want self-serve pricing based on product tier and monthly post capacity, not connected-account count

Your users are low- or medium-volume, so Growth can be more predictable than paying per connected account

You want branded OAuth through Hosted Connect — UniPost ships this on Growth ($59/mo)

Choose Zernio if:

You need 15 platforms and use ones UniPost doesn't have yet (Reddit, WhatsApp, Telegram, Discord, Snapchat, Google Business)

You need Ads management as a first-class feature

You want unlimited posts and every feature bundled with each connected account

Your connected-account count is low enough that per-account billing is predictable

MCP Comparison

Built for the AI agent era

Both UniPost and Zernio ship a native MCP server so Claude, GPT, or any MCP-compatible agent can post on behalf of your users — no custom integration code.

// Claude Desktop config

// Claude Desktop config { "mcpServers": { "unipost": { "url": "https://mcp.unipost.dev/sse", "headers": { "Authorization": "Bearer up_live_xxx" } } } }

What this means:

AI agents can list connected accounts
AI agents can publish posts
AI agents can read analytics
No custom integration code needed

Zernio also ships an MCP server. Compare the rest of the stack — pricing, free tier, bundled features — to decide which one fits.

Frequently asked questions

Can I use UniPost if I'm already using Zernio?

Yes. You can run both in parallel during migration. UniPost's Free plan gives you 100 posts/month to test the API and dashboard, while paid plans are organized around product stage and monthly post capacity.

What's the real-money difference for an embedded app?

If your app has 100 end users and each connects 2 social accounts, that is 200 connected accounts. Under Zernio's current graduated account pricing, 200 full-month accounts is $418/mo. If the same app fits under 7,500 posts/mo and Growth features, UniPost Growth is $59/mo.

Does UniPost support all the platforms Zernio supports?

UniPost supports 9 platforms (X, Instagram, Facebook, Threads, TikTok, YouTube, LinkedIn, Pinterest, Bluesky). Zernio advertises 15. If you need a network beyond UniPost's nine, check our roadmap or contact us.

Both have MCP — what's the difference?

Both ship MCP support. The deciding factor is usually packaging: UniPost self-serve plans are not priced per connected social account, while Zernio's public pricing uses an account meter.

Does UniPost have a free plan?

Yes — the Free plan includes 100 posts/month, no credit card, and no time limit. Paid plans do not include a separate time-limited trial.

Does UniPost support white-label OAuth?

Yes — UniPost ships white-label (Native mode) on the Growth tier ($59/mo) so your users see your app name on the OAuth screen. Zernio's public docs describe standard OAuth flows; verify directly with Zernio if branded OAuth is a requirement.

How long does migration take?

Most developers complete the switch in under an hour. The main change is the endpoint URL and field names.
