Overview

AICO is a voice- and chat-agent runtime. It orchestrates conversations over phone (SIP), WhatsApp, SMS, an embeddable web widget, and native clients through a graph-based flow executor that calls swappable STT, TTS, and LLM providers.

Stack

Layer	Implementation
Frontend	Svelte 5 · Vite · XYFlow (flow builder)
Backend	Bun · TypeScript · Elysia · Drizzle ORM
Database	PostgreSQL + pgvector
Cache	Valkey 8
Media	LiveKit (WebRTC + SIP) + LiveKit Egress (recording)
Agent worker	Python · LiveKit Agents SDK · Silero VAD · multilingual turn detector
Speech (self-hosted)	Multi-engine STT / TTS services with a per-model catalog (CPU / CUDA / ROCm builds)
LLM (self-hosted)	vLLM inference plane with a per-model catalog; Ollama supported
Auth	Logto (OAuth2 / OIDC)
Embeddings	embeddinggemma (768-dim)
Client surfaces	Embeddable web widget, browser extension, Android (Wear OS + wearable scanner), desktop
Observability	OpenTelemetry export (optional)

Deployment shapes

AICO ships the same application in three shapes:

Cloud (multi-tenant SaaS) — Kubernetes charts, GitOps-managed.
Dedicated instance — the full platform on a single host as a self-contained container bundle, on our infrastructure or yours (on-prem). Includes a guided update script and restore runbook.
Customer Kubernetes — the same charts with partner-supplied values for customers who run their own clusters.

All shapes are generated from one manifest pipeline, so a dedicated instance runs the same services and versions as the cloud product.
