Zernio is the marketing infrastructure 200,000 developers build products on. We absorb the integrations, platform approvals and maintenance behind every channel, all on official APIs, so you can start building today. One API covers 16 social platforms, ads on 7 networks, WhatsApp, iMessage, and phone numbers with calls and SMS that you buy inside Zernio. Use the REST API in your code, or let your coding agent do the same through our MCP server and CLI.
Hey everyone! Excited to be back on Product Hunt with Zernio :)
When we first launched here in March, Zernio was a social media API. Developers came to us so they didn’t have to build and maintain an integration for every platform, and social is still the biggest part of what we do.
Then you kept asking for more. Since then we’ve added ads across 7 platforms, WhatsApp, iMessage, and phone numbers with calls and SMS, all on the same API. Today 200,000 developers build on Zernio, and we’re finally ready to grow from a social media API into marketing infrastructure that you and your agents build on.
Connect our MCP server, and your agent can post, run ads, text and call. We have plenty of ideas for what comes next, but we’d love to hear yours.
Use this launch to tell us what you still can’t build on Zernio. Thank you all for the support!

Who hunted Zernio?
Zernio was hunted by fmerian. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
