Kapso alternatives: four WhatsApp APIs for developers
The main alternatives to Kapso for the official WhatsApp API are Nodium, 360dialog, Twilio and Meta's Cloud API used directly. Nodium is the closest in pricing model — plans by connected numbers and messages — billed in euros, hosted in the European Union, and without the inbox and AI agents that Kapso includes.
Why teams look for an alternative
- They only need the API: no team inbox, no AI agents.
- Their customers are in Europe and they want prices in euros and data hosted in the European Union.
- They want a free plan with every feature, to build before they pay.
The alternatives
