    Let's goo! That's awesome! Finally a decent API with a generous free tier. Thank you for that.

    Quick question, are you using the official Meta API on your side?

    • aamatte 2 days ago ago

      thanks! yes, we use the official Meta API

    Congrats, this is a strong primitive for modern SaaS, especially in LATAM.

    Building software today increasingly means integrating dozens of external services rather than building systems end to end. Email, auth, analytics, billing, AI tooling, and observability each come with their own accounts, configs, SDKs, and API keys.

    This composability is powerful, but increasingly inefficient.

    It makes me wonder when we’ll see a platform that bundles these services with unified accounts, billing, auth, and configuration by default, instead of having to configure and manage each one independently.

      Thanks! Agreed on the composability pain. That's part of why we bundle inbox, observability, workflows, etc, together.

    This is really really cool, and thank you for the free tier as well.

    Always been a bit put off using WhatsApp as I've seen the pain some devs have had to go through to integrate it, this looks smooth.

    Excited to have a play around with this.

    • aamatte 2 days ago ago

      thanks! and yeah, the integration pain is exactly why I built this.

      let me know what you think once you try it!

        Documentation and sandbox is good, however is the facebook account a hard requirement to getting a number and templates setup? I've paid the $6 for a number however I don't have (or want) a facebook account, so seems I'm a bit stuck.

    Do you have support for whatsapp group management?

  • francofantini 2 days ago ago

    I've been using Kapso for the last couple of months, and it’s flawless.

    Love it. Any plans for other integrations like instagram/linkedin?

    • aamatte 2 days ago ago

      Thanks! For now we're focused on going deeper on WhatsApp. There's still a lot to build. But other channels aren't off the table eventually.

    Hey aamatte, why do you charge 95% less than Twilio?

    • aamatte 2 days ago ago

      Twilio priced WhatsApp messages like SMS: $0.005 per message.

      That made sense for SMS where you send one message and you're done.

      But WhatsApp conversations don't work that way. People send bursts of short messages instead of one long one.

      A typical conversation can easily hit 30-50 messages. Building AI agents with that pricing gets expensive fast.

      At Twilio's rates, 100k messages would cost you $500.

      Our Pro plan is $25/month and includes 100k messages.
