Ayrshare vs Zernio
If you're embedding social posting into a product (an AI platform, a multi-tenant SaaS, or an agency platform), here's the side-by-side. Zernio wins on sticker price at low volume. Ayrshare wins on everything your product needs next, and on total cost the moment your customers post to more than a couple of networks.
Ayrshare
The reliable API infrastructure choiceThe full social lifecycle in one integration: publishing to 13+ networks, History API, analytics, DMs, ads, and a hosted MCP server, with documented compliance. Billed per social profile, so your cost doesn't climb when customers add networks. And when you're betting your product on a vendor, maturity matters: 4+ years at 30M+ daily API calls, with 24/7 engineering-backed support when something breaks. 1-month free trial.
Zernio
THE NEWER LOW-VOLUME OPTIONA new startup covering a wide network list: free up to 2 accounts, 15 networks including WhatsApp and Discord today, and paid ads across six networks. Entry price is lower, with the trade-off in lifecycle depth, documented compliance, and track record.

Per profile vs. per connection
Ayrshare bills per social profile (brand): one profile can connect every network and still counts as a single billing unit, regardless of how many networks it posts to, so adding a network costs $0 more. Zernio bills per connection: every network a brand posts to is a separate billing unit, plus per-request X charges. As your customers add networks, the two models pull apart.
What each Ayrshare plan includes, in social accounts. Ayrshare bills per social profile (brand), and each profile can connect all 13 networks, so every plan bundles a block of social accounts at a flat price. Here's each plan at full capacity next to what those same social accounts cost on Zernio's per-account pricing.

The bottom line. Zernio is cheaper for a single brand. But Ayrshare's flat per-profile price means the more networks your brands use, the less you pay per account, undercutting Zernio's $3 tier from the Launch plan up. Zernio's number also leaves out per-request X and WhatsApp fees, plus capabilities it doesn't ship at all (History API, Validation, X BYOK, RSS auto-posting).
Which one is right for you?
Pick Ayrshare when
You're building a product that needs the whole social lifecycle, beyond a single posting endpoint.
You're training AI on a brand's voice: the History API gives you past posts with no cold-start.
Compliance is a sign-off requirement: Validation API, OAuth built for platform policy, documented X BYOK.
You're scaling a multi-tenant SaaS or agency and your customers post to several networks each.
You're weighing total cost, not sticker price: per-profile billing that scales with your revenue and drops per identity at volume, not per-post fees that balloon when an agent posts at scale.
You want a proven vendor: 4+ years in production with 24/7 engineering-backed support.
Pick Zernio when
You're posting at low volume to a few accounts and want the smallest upfront cost to start
You need WhatsApp or Discord now (WhatsApp coming to Ayrshare; Discord is Zernio-only).
You want broad cross-network paid ads across six ad networks.
You prefer the simplest possible billing: per connected account, nothing bundled.

Moving from Zernio is mostly endpoint mapping
Both are REST APIs with comparable shapes, so the work is mapping endpoints, switching webhook URLs, and re-running OAuth for your end users. Typically 1–2 sprints to production cutover. We'll hand your team a one-page endpoint diff and stay with you on Slack through the OAuth and validation cutover. No ticket queue.
Common questions
For a single brand at low volume, yes. Zernio's per-connection pricing starts lower. But Ayrshare bills per social profile (brand) at a flat rate, so the more networks each brand uses, the less you pay per account. From the Launch plan up, Ayrshare comes in cheaper, and Zernio's sticker price leaves out per-request X and WhatsApp fees.
Ayrshare publishes to 13 major networks today, with WhatsApp coming soon. Zernio lists 15, the extras being WhatsApp and Discord. For everything beyond posting (History API, Validation API, analytics, and documented X BYOK), Ayrshare covers ground Zernio doesn't.
Ayrshare has run in production for 4+ years at 30M+ API calls per day, with a 99.99% Enterprise SLA, published per-profile rate limits, and 24/7 engineering-backed support. Zernio is a newer startup citing a 99.97% SLA and ~2.3M posts delivered in total.
History API (pull 200–500 past posts per profile), Validation API for pre-publish checks, documented X BYOK, RSS auto-posting, a hosted MCP server with a Claude Code plugin, and a full management dashboard, all in one integration billed per social profile.
Both ship an MCP server. Ayrshare's is hosted, with a Claude Code plugin, 27 tools, Profile-Key auth, and X BYOK, plus a History API that gives agents real past posts to learn a brand's voice with no cold-start. Zernio markets 280+ tools.
Mostly. Both are REST APIs with comparable shapes, so migration is largely mapping endpoints, switching webhook URLs, and re-running OAuth for your end users, typically 1–2 sprints. We'll hand your team a one-page endpoint diff and stay with you on Slack through the cutover.
When the lowest entry price matters most and you're at low volume, when you need WhatsApp or Discord today, when you want broad cross-network paid ads across six networks, or when you prefer the simplest possible per-connection billing with nothing bundled.
