Zernio

What it does

Zernio provides a single API for publishing, inbox, analytics, ads, and account management across 15 platforms, including social networks (Twitter/X, Instagram, TikTok, LinkedIn, Facebook, YouTube, Threads, Reddit, Pinterest, Bluesky, Snapchat, Google Business) and messaging apps (WhatsApp, Telegram, Discord). It also supports ad networks (Meta Ads, Google Ads, LinkedIn Ads, TikTok Ads, Pinterest Ads, X Ads). The API is available via REST, SDKs (Node.js example shown), CLI, and a hosted MCP server with 280+ tools for AI agents. Key capabilities include: connecting accounts via hosted OAuth (no developer apps needed), creating posts that go to multiple platforms in one call, purchasing WhatsApp phone numbers (with KYC handled), unified analytics, boosting posts to ads, webhooks for event notifications, and a unified inbox for DMs and comments.

Who it is for

Zernio targets developers and AI agent builders who need to integrate social media and messaging features into their products. The website lists customers like ClickUp, RE/MAX, Warner Music Group, and several SaaS founders (e.g., HeyMark, Vibiz, purplepalm.ai, captureflow.ai). Testimonials come from web developers, founders of coaching apps, ad-attribution SaaS, and developers using Claude Copilot. The product is positioned for those who want to avoid maintaining custom integrations for each platform, with claims that custom integrations take 8-12 months while Zernio takes under an hour.

Why it matters

Managing multiple platform APIs is time-consuming and complex. Zernio abstracts away the need to create developer apps, handle OAuth flows, manage quotas, and deal with platform-specific quirks. It offers a unified interface for publishing, messaging, analytics, and ads, which can accelerate product development. The inclusion of an MCP server makes it particularly relevant for AI agents, allowing them to interact with social media in plain language. The product is SOC 2 and GDPR compliant, and claims to be white-label friendly (no Zernio branding shown to end users).

Launch signal

Zernio has been featured on Product Hunt with a 5.0 rating from 2 reviews and 560 followers. The website shows a live counter of 521,814 posts and 11,441 accounts connected this week (as of the time of scraping). The product has undergone a rebrand from getlate.dev to zernio.com. It is bootstrapped, founded by Miquel Palet. The website includes case studies from customers HeyMark and Vibiz.

Brand and naming

Zernio is a coined name that sounds modern and tech-forward, but it lacks inherent meaning or connection to social media or APIs, making it less intuitive. The domain zernio.com is short and memorable, though the name itself may require brand-building to gain recognition. The tagline and website clearly position it as a unified API for social media and messaging, targeting developers and AI agents, which is a strong, differentiated value proposition.
