Zernio is marketing infrastructure for products and agents: one API for social, ads, messaging and calls.
Instead of building an integration for every channel, each with its own API, auth and review process, you integrate once, on official platform APIs, and most teams launch the same day.
Social, ads, unified inbox, SMS, RCS, iMessage, WhatsApp, calls and numbers in 57 countries. A hosted MCP server lets agents connect accounts, run campaigns, send messages and place calls on their own.
This is the 4th launch from Zernio. View more
Zernio
Launching today
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.

Congrats to the team on the launch! I’ve been using it for the last 4–5 months and have found it super easy to onboard and use. Such an awesome team! Thanks, guys, for building such an amazing product.
@ankur_khandelwel thanks so much for the kind words, Ankur. Really happy to hear you're having great experience with Zernio!
Whether you're vibe coding, no coding or just coding Zernio is a massive time saver.
@mattblake_uk Love this! Thank you for support, Matt 🙌
Zernio is one amazing product that solves a lot of problems for small time developers like us.. Superb support, easy to use features and a really simple pricing model..
Absolutely love it!
@dkspeaks this means a lot, thank you!
Cracked team that are constantly shipping good stuff! Congrats with the launch guys 🙌
Do you handle US A2P 10DLC registration for the numbers, or is that on the developer? That's usually the slowest part of getting SMS live, and it's where agent-sent texts get filtered without anyone noticing.
@lancelot_d_souza1 Zernio handles it. You send the business and campaign details in one API call, and Zernio files the 10DLC registration and tracks it through approval
Been using Zernio since July, and the best compliment I can give is that I barely open it.
I work in batches: make a week’s worth of content, hand it to Claude Code, and it schedules everything across platforms through the API. When the agent gets stuck, it asks your MCP docs instead of me (the best support ticket is the one I never see). Posting to every platform by hand used to be a pain of my existence (slightly exaggerated, but only slightly). Now it’s not a task. Not a tab I keep open. Just plumbing that works.
Congrats on the launch!
the phone numbers with calls and SMS bought inside Zernio is the part I'd stress test first. we build voice agents at Dial and the actual hard part of telephony was never the API shape, it was the carrier-side stuff - A2P 10DLC registration for SMS, STIR/SHAKEN attestation so your calls don't get flagged as spam, and the week-plus approval lag when a carrier decides your use case looks sketchy. does Zernio absorb that compliance layer too, or is "buy a number inside Zernio" still handing the user a number that can get silently throttled by a carrier for reasons outside your API
