Overview

What Is feros

High-level introduction to feros and where it fits.

What Is feros

feros is an open-source, self-hostable voice agent infrastructure stack.

It combines:

  • A Python control plane (studio/api) for agent config, integrations, settings, and evaluations
  • A Rust telephony gateway (voice/server) for inbound call/websocket session setup
  • A Rust runtime engine (voice/engine) for real-time STT -> LLM -> TTS orchestration
  • A web dashboard (studio/web) for builder workflows, testing, calls, and operations

Why Teams Use feros

  • Avoid per-minute managed-platform lock-in
  • Keep architecture fully self-hostable
  • Replace provider components (STT, LLM, TTS, telephony) without rewriting the full stack
