Build AI chatbots, automate customer support workflows, and connect live agents across web, WhatsApp, email, and voice with a no-code visual designer.

Tiledesk is an open-source platform for building AI agents that handle customer support, appointment booking, email processing, and more, without writing code. It's built for businesses that want to automate conversations at scale while keeping humans in the loop when it matters.
The core of the platform is a visual flow builder where you design conversation logic using prompt chains, LLM calls, and conditional routing. You can create multiple specialized agents (one for sales, another for support, another for onboarding) and chain them together so a conversation moves between them based on intent or topic. It's a practical alternative to other chatbot platforms that force you to choose between simple bots and full custom development.
Key capabilities:
Compared to tools like Botpress or Hexabot, Tiledesk leans heavily into the enterprise self-hosting angle. You can run the entire stack behind your own firewall, control your vector store, and connect open-source models, which matters for regulated industries like healthcare, finance, and public sector.
The platform is GDPR-compliant and Italy-based. It supports SSO, integrates with existing live agent consoles and VoIP systems, and includes an MQTT-based real-time debugger for testing automations. A 14-day free trial is available without a credit card.
Messaging Infrastructure for Developers. One API for SMS, WhatsApp, and RCS across 190+ countries.
