Show HN: Kapso – WhatsApp for developers
Show HN: Kapso – WhatsApp for developers Hey HN, I'm Andres. I've been building Kapso as a solo founder, and just crossed 4,000 developers, all organic.<p>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.<p>But it’s not happening… And I'd bet it's because the DX is painful.<p>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.<p>That’s why I built Kapso. What you get:<p>- Working WhatsApp API + inbox in 2 minutes, not days - Full observability: every webhook parsed, every message tracked, actual debugging tools - Multi-tenant platform: generate a setup link, customer connects their Meta account, done - Workflow builder for deterministic automations and AI Agents - WhatsApp Flows: build mini apps inside WhatsApp using AI + serverless functions - Docs that work for humans and LLMs<p>We're up to 95% cheaper than Twilio, with a generous free tier (2,000 messages per month).<p>We also open source several tools: a TypeScript client for the WhatsApp Cloud API, a reference WhatsApp Inbox implementation, and a voice AI agent for WhatsApp.<p>GitHub: <a href="https://github.com/gokapso/" rel="nofollow">https://github.com/gokapso/</a><p>Happy to answer questions!<p><a href="https://kapso.ai/" rel="nofollow">https://kapso.ai/</a>
