24 alternatives to Zernio
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 requires a developer app, a WhatsApp Business Account inside Business Manager, business verification (2-14 days), phone number OTP, webhook configuration with a two-step subscription, and token management for tokens that die every 60 days. Miss one step and messages vanish with no…

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 Aria▲163I 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…

Hi HN, I built this out of frustration of the evergrowing list of AI models and features to try and to fit my workflow. The visual approach clicks for me so i went with it, it provides more freedom and control of the outcome, because predictable results and increased productivity is what I’m after when using conversational AI. The app is packed with features, my most used are prompt library, voice input and text search, narration is useful too. The app is local-first and works right in the browser, no sign up needed and it's absolutely free to try. BYOAK – bring your own API Keys. Let me…

Amber▲133Hi HN! Excited to share early access to Amber. I’ve tried every all-in-one messenger out there (Beeper included) but they always fell short. No real folders, no AI, clunky UI, no CRM features… As a founder who speaks with hundreds of people every quarter, I needed something better. So I decided to rebuild the entire experience from ground up. Thoughts from one of our users: "The app I've been searching for for a looong time." Check it out for free today! Demo: https://www.loom.com/share/8b5bc80b9893436b9190ae41fc3f0f50 Features: - All messages (Whatsapp, Telegram,…

Post for Me▲17Building integrations for TikTok, X, Facebook, Instagram, YouTube, and LinkedIn got frustrating with how different every platform is with auth setup, rate limits, and media requirements. So we built Post for Me: one REST API that handles scheduling and publishing posts for TikTok, Facebook, Instagram, X, YouTube, LinkedIn, Pinterest, Bluesky, and Threads. It's built for developers. You bring your own app credentials from the social platform, so you're in control of your data. There's no limitations on account connections, and pricing is based on usage (not some arbitrary limitations). We…

I wrote this over the last couple of weeks using Rails 3, Twilio and a variety of Gems, putting in about 2 hours per day. I'd love any feedback from the HN community on any aspects of the site (design, API construction, documentation, marketing, pricing which is TBD). On a related note: I have to say that I'm really flying with Rails 3. Typically I roll with Django, but have been super impressed with the Rails 3. Feels really clean, and there are some Gems that make the more mundane parts of the webapp construction fun and agile: Haml/Sass, blueprint, Fancy-buttons, Devise. I'll probably…

PostFast▲29I wanted to free my time for working out and my family, so I built a social media scheduler that doesn't break all the time. It has cross-posting across all major social media platforms. The platform is built with NestJS, Kafka, Redis for the backend, Nextjs for the landing, and React with Vite for the frontend private part. I'd love to get your thoughts on what more inside would save you time from going to all those different platforms one by one.
