Boilerplate-free voice agents.

Define a prompt, register Python functions as tools, deploy — across four voice-agent backends. minmo handles JSON-Schema generation, local tool hosting and tunneling, and each provider's REST API, so you write the assistant, not the plumbing.

Why minmo

Zero boilerplate: One decorator turns a typed Python function into a real, reachable tool. One deploy() call ships it.
Provider-agnostic: The same VoiceAgent API works across AssemblyAI, Hume, and ElevenLabs — three backends that don't share a wire protocol.
Fail fast, explain: Typed errors and a plain-language "info" string on every deploy() result: what happened, what to do next.
Test without spending: simulate() runs your tool logic against any OpenAI-compatible LLM — no live voice session, no burned minutes.
