Before you choose
Start with access and cost
Check whether a platform has a free plan, a free trial or a paid entry price. LiveKit Agents lists a free plan with paid service from $50 per month, while Vapi lists a free plan and pricing from $29 per month.
Amazon Lex lists a free plan with pricing from $0.00. Hume AI lists a free plan with paid service from $3 per month. Avaamo lists pricing on request and a 30-day trial.
Choose where it runs
Compare the deployment options you need: web, API, self-hosted, iOS, Android or macOS. A platform may support one route or several, so match this field to your product and operations.
Check chat and voice channels
The comparison includes voice channel and chat channels. Review both when a service must handle spoken conversations as well as text interactions.
Review AI and language needs
Use the generative AI and languages fields to check whether a platform fits the responses and locales you plan to support. Keep these requirements separate from channel and deployment choices.
Consider source and handoff
If you need to read or change the code, check the tool's licence and hosting model. Pipecat is listed as open source, while the list also records self-hosted availability.
Human handoff shows whether a service can pass a conversation to a person. Check that field when support teams need a live escalation path.
