Ordered by the requirements met, strengths preserved, explicit trade-offs and research coverage. Sponsorship does not enter the order.
- 01
ElevenLabs Agents
Hosted platform for building voice and chat agents, with telephony, SDKs and a choice of LLM.
From FreeWhy it's on this listMulti-agent · YesAn orchestrator agent routes a live conversation to specialist agents on natural-language conditions, and transfers can be nested; the transcript carries across.Evidence ↗
Where it improves on HeyRik
- +Agent permissions · YesTool use is gated per MCP server and per tool: always ask, fine-grained (auto-approved, requires approval, disabled), or no approval at all.Evidence ↗
- +Model choice · YesYou pick the model per agent, plus a backup cascade; LLM usage is billed on top of the plan and varies by model.Evidence ↗
Trade-offs against HeyRik
No disadvantages found in the criteria researched so far.
35/35 researched criteria - 02
Synthflow
Enterprise voice AI platform with in-house telephony for inbound and outbound call automation.
From FreeWhy it's on this listMulti-agent · YesSubflows act as specialised agents that a parent flow triggers for individual tasks.Evidence ↗
Where it improves on HeyRik
- +Agent permissions · YesFlow logic, approved knowledge sources, end-call reasons and handoff triggers bound what an agent may say or do.Evidence ↗
- +In your editor · PartialNo Synthflow editor extension; Claude, Claude Code and Cowork can drive the workspace over MCP from where a developer already works.Evidence ↗
Trade-offs against HeyRik
No disadvantages found in the criteria researched so far.
35/35 researched criteria - 03
Vapi
Developer platform for building, testing and deploying voice AI agents that make and receive phone calls.
From $0.05/minuteWhy it's on this listMulti-agent · YesSquads route one conversation across several specialised assistants with context-preserving handoffs.Evidence ↗
Where it improves on HeyRik
- +Model choice · YesYou choose transcriber, LLM and voice independently and can swap any of them.Evidence ↗
- +In your editor · PartialNo agent runtime in the editor; `vapi mcp setup` teaches Cursor, Windsurf and VSCode the Vapi API so you can build from the IDE.Evidence ↗
Trade-offs against HeyRik
- −Opt out of training · PartialThe privacy policy reserves call content for model training and names no toggle; the $1,000/month ZDR add-on is the only documented way to stop it being kept at all.Evidence ↗
35/35 researched criteria - 04
Retell AI
Platform for building, testing and deploying AI voice and chat agents on phone, web and SMS, billed per minute.
From $0.07/minuteWhy it's on this listMulti-agent · YesAgent Transfer (agent swap) hands a live call from one AI agent to another with full transcript inherited; subagent nodes attach tool-using agents inside a flow.Evidence ↗
Where it improves on HeyRik
- +Model choice · YesYou pick the LLM per agent from a published menu of 20+ models, each with its own per-minute rate, plus a fast tier and a custom-LLM escape hatch.Evidence ↗
- +In your editor · PartialRetell's own MCP server lets Cursor, Claude Desktop, Claude Code and Codex-style clients create, publish and inspect agents; the agent itself never runs in an editor.Evidence ↗
Trade-offs against HeyRik
- −Opt out of training · NoThe privacy policy lists training its AI models among the uses of collected data, and its 'Your Choices' section offers only account deletion, cookie preferences, marketing opt-out and sale/sharing opt-out, with no training opt-out.Evidence ↗
34/35 researched criteria · 1 not established - 05
AudioCodes Live Hub
Self-service SaaS for building voice AI agents and connecting them to SIP trunks, Teams, WhatsApp and WebRTC.
From $0.05/minuteWhy it's on this listMulti-agent · YesSpecialised agents exchange messages and split a call between them, with four documented orchestration modes and per-agent model choice.Evidence ↗
Where it improves on HeyRik
- +Model choice · YesYou choose the LLM per agent and may substitute any supported provider with your own key, and equally bring a third-party conversational AI platform instead.Evidence ↗
- +On the command line · PartialAudioCodes ships no CLI of its own; the only terminal path is registering its MCP server with Claude Code, whose binary does the work.Evidence ↗
Trade-offs against HeyRik
- −Opt out of training · PartialAudioCodes never trains on customer data, but data you route to third-party AI providers falls under their policies and you must configure that yourself.Evidence ↗
33/35 researched criteria · 2 not established - 06
Cartesia
Real-time speech models and a managed runtime for production phone and web voice agents.
From FreeWhy it's on this listModel choice · YesYou pick the agent's LLM and can swap it in the Playground or API; Cartesia owns the speech models and manages the LLM integration.Evidence ↗
Where it improves on HeyRik
- +In your editor · PartialNo native IDE extension; the documented editor surface is the Cartesia MCP server used from Cursor or Claude Code.Evidence ↗
- +On the command line · YesA `cartesia` CLI creates, deploys and manages agents, and can chat with agent logic locally.Evidence ↗
Trade-offs against HeyRik
- −Done-for-you service · NoSelf-serve software: you build and deploy the agent yourself; sales contact exists for Enterprise terms, not for building it for you.Evidence ↗
- −Opt out of training · PartialOpt-out is by request form for selected categories of content; Enterprise plans can additionally enable Zero Data Retention for TTS and STT inference.Evidence ↗
