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 listAgent 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 ↗
Where it improves on Leaping AI
- +Open source · PartialThe CLI and the client SDKs are public on GitHub and take contributions; the agent platform and the speech models themselves are proprietary and hosted.Evidence ↗
- +How it meters · YesA monthly plan buys included call minutes and concurrency; overage is per minute, texts are per message, and LLM plus telephony are billed on top at usage.Evidence ↗
Trade-offs against Leaping AI
- −Audit log · PartialOCSF-schema logs over 100 administrative endpoints, pullable into a SIEM, but gated on Enterprise tier plus an API key holding audit_log_read.Evidence ↗
- −Data residency · PartialUS by default; EU, India and Singapore exist as separate Enterprise workspaces with their own accounts, API hosts and reduced model choice, and processing may still leave the region.Evidence ↗
35/35 researched criteria - 02
PolyAI
Enterprise platform for building voice and chat agents that resolve customer calls, priced per minute.
Why it's on this listOpen source · PartialThe ADK CLI and Python package are Apache-2.0 in PolyAI's public repository; the platform, Agent Studio and the Raven model are proprietary.Evidence ↗
Where it improves on Leaping AI
- +How it meters · YesMetered by conversation volume, not seats: the MSA credits two CX Tokens per call minute and one per chat, with call time rounded up to 30-second increments.Evidence ↗
- +Free tier · YesSelf-serve sign-up at Agent Studio needs no sales call, and trial use is free of charge but evaluation-only, with limits set at PolyAI's discretion.Evidence ↗
Trade-offs against Leaping AI
- −Self-hosted · NoRuns only as PolyAI-hosted SaaS on AWS with region-specific workspaces; no on-premise or customer-cloud deployment appears anywhere in the vendor's docs or security pages.Evidence ↗
- −Audit log · PartialPermission-change audit logging is stated for Enterprise accounts only; every published version and change is separately kept as project history.Evidence ↗
35/35 researched criteria - 03
AudioCodes Live Hub
Self-service cloud platform for building voice AI agents and connecting them to real telephony channels.
From $0.05/minuteWhy it's on this listHow it meters · YesBilling is metered per minute per consumed service, so a bot connection, speech service, voice channel and LLM tokens are each charged separately rather than by seat.Evidence ↗
Where it improves on Leaping AI
- +API access · YesA documented REST API under /api/v1/ configures the platform and reads back calls, recordings, transcripts and campaigns, with OAuth 2.0 client-credentials authentication.Evidence ↗
- +Bring your own key · YesYou may supply your own keys for both inference and speech: custom LLM providers are configured with your API key, and STT/TTS accounts can be brought in the same way.Evidence ↗
Trade-offs against Leaping AI
- −Claude · PartialClaude models are supported only as bring-your-own custom models configured with your own Anthropic API key; the pre-deployed model list carries OpenAI and Google models only.Evidence ↗
- −Self-hosted · NoLive Hub is a vendor-operated SaaS running in AudioCodes' own Azure deployments; the only customer choice is which of four regions holds the data, not whose infrastructure runs it.Evidence ↗
33/35 researched criteria · 2 not established - 04
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 listOpen source · PartialThe CLI and SDKs are MIT-licensed on Vapi's GitHub; the platform and its orchestration models are closed and hosted.Evidence ↗
Where it improves on Leaping AI
- +How it meters · YesPer call minute for Vapi hosting, plus model provider cost passed through at cost, plus $10 per concurrent line per month.Evidence ↗
- +Free tier · YesSelf-serve signup with a $5 credit grant and no card; it is a grant against usage, not a standing free tier.Evidence ↗
Trade-offs against Leaping AI
- −Audit log · PartialThe dashboard keeps org-wide API, call and webhook logs and assistant version history; no member-action audit trail is documented.Evidence ↗
- −Data residency · PartialUS is the default region; the EU region is frozen to existing accounts and new EU residency is enterprise-only, so regional control comes from your own buckets and models.Evidence ↗
- −Certifications · PartialSOC 2 Type II and a HIPAA BAA sit in the Scale contract, and the plan table shows SOC2 only in that column; HIPAA mode is a $2,000/month add-on on either plan.Evidence ↗
35/35 researched criteria - 05
Cartesia
Real-time speech models and a managed runtime for production phone and web voice agents.
From FreeWhy it's on this listOpen source · PartialThe official JS/TS and Python client SDKs are public repositories on Cartesia's GitHub; the Sonic and Ink models and the agent runtime are not.Evidence ↗
Where it improves on Leaping AI
- +How it meters · YesTwo meters: credits for the models (about 1 credit per TTS character, 3 credits per second of Ink-2 audio) and per-minute US dollars for agent calls.Evidence ↗
- +Free tier · YesA $0/month plan with 20K credits and $1 of prepaid agent usage, signed up for without a call.Evidence ↗
Trade-offs against Leaping AI
- −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 ↗
- −Audit log · PartialDeployment logs, call logs and transcripts are recorded per agent; no administrative audit trail of account actions is documented.Evidence ↗
- −Data residency · PartialBy default api.cartesia.ai routes to the nearest endpoint; pinned regional deployments (US, EU, UK, India, Australia) are Enterprise-only.Evidence ↗
35/35 researched criteria - 06
Deepgram Voice Agent API
One WebSocket API that runs speech-to-text, LLM orchestration and text-to-speech for real-time voice agents.
From $0.05/minuteWhy it's on this listOpen source · PartialThe client SDKs are MIT-licensed on Deepgram's own GitHub, and the browser agent packages ship on npm; the Voice Agent runtime, the STT and TTS models and the self-hosted containers are proprietary and license-server validated.Evidence ↗
Where it improves on Leaping AI
- +How it meters · YesMetered per minute of WebSocket connection time, one rate covering STT, LLM and TTS together; the tier depends on which LLM you pick and whether you bring your own LLM or TTS. Billing is true per-second, not rounded up.Evidence ↗
- +API access · YesThe product is the API: one WebSocket at /v1/agent/converse, with official SDKs for JavaScript, .NET, Python, Go and Java, all marked GA.Evidence ↗
Trade-offs against Leaping AI
- −Done-for-you service · NoSelf-serve software you build against: you sign up, get an API key and write the client. Enterprise brings an account representative and a contract, not a team that builds and runs the agent for you.Evidence ↗
- −Audit log · PartialPer-request logs (90 days in console, longer via the Usage API, with per-request USD cost) plus per-session message observability; no administrative-action audit trail is documented.Evidence ↗
- −Data residency · PartialEU and AU endpoints both serve the agent WebSocket, and Deepgram runs listen and speak in-region; managed LLM traffic is routed in-region only for OpenAI and Google in the EU, and on the AU endpoint the think step is processed outside Australia. Dedicated adds a customer-chosen AWS region.Evidence ↗

Comparable first. We consider listings in the same category as Leaping AI and alternatives previously researched for this page.
Requirements first. We prioritise your selected needs, then shared strengths, fewer documented trade-offs, more complete research and finally alphabetical order.
Unknown remains unknown. Missing evidence is never converted into a benefit or a trade-off. Every improvement shown above comes from the same sourced criterion as the listing.
Independent order. Payment does not affect selection or ranking. Paid placements are labelled Advertisement.
