An alternative to Vapi, hosted in Switzerland

Vapi is a developer platform for voice AI agents built around the integration of many model providers. SwissAI takes a different route: the models are included, each agent gets a SIP URI, and everything runs in Switzerland. Which one fits depends on what you are building.

Where the two differ

Models: Vapi lets you combine LLM, transcription and voice providers of your choice. SwissAI includes speech recognition, a language model and text-to-speech, selectable per agent, with no separate provider accounts.
Telephony: on SwissAI every agent has a SIP URI; you connect a PBX by IP address, register a number you already own, or request a Swiss or European geographic number from the dashboard.
Hosting: SwissAI runs in Switzerland; calls, transcripts and logs stay there. Vapi's public site does not state a hosting region.
Pricing: SwissAI plans include minutes and bill extra minutes per second at one rate that covers models and telephony. No per-seat fees.
Scope: SwissAI is a dashboard-first product with HTTP tools, a chat API, WebRTC clients and WhatsApp; Vapi exposes a broader programmable surface for teams building their own stack.

When SwissAI is the better fit

You need the data to stay in Switzerland or in Europe.
You have a PBX or a SIP trunk and want to route calls to an agent without building telephony.
You want one bill per minute rather than several provider accounts.
You serve several customers and want each one with its own agents, tools and price list.

When Vapi may fit better

You want to pick and swap specific model providers yourself.
You are building a custom voice application in code rather than configuring agents in a dashboard.

Moving an agent over

An agent on SwissAI is a prompt, a language, the models and a list of HTTP tools. If your current tools are HTTP endpoints with a JSON schema, they can be described in the Tools section as they are. The 30-day trial with 100 minutes lets you compare on your own calls.
