Self-hosted vs cloud
AI voice agents: how to choose

Both run the same VEXYL platform. The question is who operates it and where your call audio lives. Use this guide to pick, and switch later if your needs change.

Self-hosted VEXYL Cloud
Who operates it Your team, on your servers or VPC VEXYL
Where audio and transcripts live Only on your infrastructure VEXYL-run infrastructure
Setup Single binary or Docker, plus your SIP trunk and keys Point a SIP trunk at us, add the widget; we map DIDs to bots
Telephony Direct to your Asterisk / FreePBX, SIP trunk or PSTN gateway SIP trunk from your PBX by static IP, Opus or G.711
Model keys Yours, paid directly to providers Arranged with VEXYL
Cost shape Licence by concurrent calls; free up to 4 Talk to sales

Choose Self-hosted when

  • Patient, financial or government data must not leave your network.
  • You have an ops team and existing Asterisk or FreePBX.
  • You want the lowest marginal cost per minute at volume.

Choose VEXYL Cloud when

  • You want to go live without running servers.
  • You have a PBX with a static IP and just need the AI side handled.
  • You want VEXYL to own uptime and upgrades.

Frequently Asked Questions

Is self-hosted voice AI cheaper than cloud?

At volume it usually is, because you pay model providers directly and avoid per-minute platform fees. A live VEXYL hospital deployment runs at about Rs 0.83 per minute all-in.

Can I start on VEXYL Cloud and move to self-hosted later?

Yes. It is the same platform, so bots, prompts and tools carry over; you repoint your SIP trunk.

What do I need to self-host?

A Linux server, a SIP trunk or Asterisk / FreePBX, and API keys for your chosen STT, LLM and TTS providers. Follow the binary or Docker quick start in the docs.
