Competitor figures are drawn from each vendor's public pricing pages and product docs as of August 2026 — verify current terms directly with the vendor before relying on them.
Every platform on this page is a managed SaaS you route live calls through. Talkr is the only one that can run entirely inside your own infrastructure — no third party sits in the call path unless you want one there.
Vapi, Retell, and Bland all add a markup on top of the LLM/STT/TTS costs you'd pay anyway. Talkr's cost is the provider costs plus your own infrastructure — nothing layered on top.
Swap LLM, STT, TTS, and telephony provider independently, per organization, with your own keys. Most platforms here lock you to their own orchestration layer or a curated shortlist.
Seven native telephony providers — including self-hosted Asterisk/ARI — is unusually wide for a platform this size. Most competitors integrate two or three.
Build and edit a live agent by talking to Claude, Codex, or Cursor — and separately, let the agent itself call out to any MCP server mid-call. Not documented as available on any other platform in this table.
If you're comparing voice-agent platforms and need to run inside your own infrastructure, choose your own model and speech providers, or stop paying a per-minute markup on top of provider costs — that's exactly the gap Talkr fills. If what you actually need is a full contact-center replacement — IVR, automatic call distribution, agent-assist — Cognigy and PolyAI solve a different, heavier problem than a voice-agent platform does.
