Work / Self-hosted WhatsApp gateway
Automation and AI
One-time codes and messages, sent from our own servers.
We run an open-source WhatsApp gateway on our own infrastructure and connect it to Anni, so customers get their sign-in code on WhatsApp in seconds. Multi-session, signed webhooks, an API, and n8n nodes for automations. We did not write it. We chose it, branded it and operate it.
