Zernio

What it does

Build social media features at scale. Zernio provides a single API for publishing, inbox, analytics, and account management across 14 platforms, so you can ship product instead of wasting time with platform APIs.

Unified social media & messaging API: post, schedule, message and engage across 16 platforms with one REST call. Free up to 2 accounts, then usage-based per account. MCP server for AI agents.

Using an AI agent? Copy a setup prompt and it connects over MCP. One integration covers social, messaging, voice, and ads. Platform changes, token rotations, and rate limits are ours to absorb. const { data : post } = await zernio.posts.createPost({ body : { content : 'Launch day!' , mediaItems : [{ type : 'video' , url : videoUrl }], platforms : [ { platform : 'instagram' , accountId : 'acc_xxx' }, { platform : 'linkedin' , accountId : 'acc_yyy' }, { platform : 'tiktok' , accountId : 'acc_zzz' }, ], publishNow : true , }, }); Launch day! Post, schedule, reply to comments and DMs, pull the analytics. Sixteen networks, one API. Post, schedule, reply to comments and DMs, pull the analytics.…from zernio.com

In the maker’s words, at launch

Hey HN, I'm Pau. We've been building Zernio for the past 9 months and we just crossed $1M in ARR (bootstrapped). Zernio is a unified API for social platforms. One API for Instagram, TikTok, YouTube, LinkedIn, X, and 9 others. Today we're adding WhatsApp. We've spent 3 weeks just getting a test message to send. Meta…

  Kapso – WhatsApp for developersDec 2025 · kapso.ai · ▲48

  Hey HN, I'm Andres. I've been building Kapso as a solo founder, and just crossed 4,000 developers, all organic. WhatsApp has 3B+ users and 98% open rates. You'd expect developers to be building tons of stuff on it, especially when the US is the fastest-growing market in WhatsApp usage. But it’s not happening… And I'd bet it's because the DX is painful. Every team needs to build the same features again and again. Meta fires webhooks for everything. There's valuable data in there for debugging, but no way to make sense of it without building your own tooling. That’s why I built Kapso. What you…

  Hello AriaApr 2026 · helloaria.io · ▲163

  I built HelloAria because every task manager I tried required too many steps to do something simple. The core idea: say "remind me to review the PR tomorrow at 10" and it creates the task, sets the reminder, and files it. No forms, no manual input. It works on iOS natively and also through WhatsApp, Telegram, and email — so you can capture tasks from wherever you already are. Tech stack: Swift/SwiftUI on the client, with NLP handling the intent parsing and entity extraction from natural language input. Looking for feedback from the HN community. What would make this actually useful for…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
