We looked for open-source platforms that build voice agents with speech, language models, and phone integration like Vapi. We verified each project's license, recent activity, stars, and self-hosting in its repository. See our methodology for the full criteria.
LiveKit is an open-source framework and cloud platform for voice and video AI agents, with a unified interface to speech, language, and text-to-speech providers, SIP telephony, turn detection, and interruption handling. LiveKit Cloud includes 1,000 free agent minutes per month.
Dograh is a BSD-2-Clause self-hostable voice agent platform with a visual workflow builder, an MCP server, several telephony providers, and on-premises or air-gapped deployment. You bring your own speech and language models.
LiveKit is Apache-2.0. Dograh is BSD-2-Clause.
Both had commits within days of this update.
Vapi is a proprietary platform priced per minute, with calls and transcripts hosted by Vapi. Open-source platforms can keep call data in your infrastructure, but you assemble speech and model providers.
LiveKit is an Apache-2.0 open-source real-time media server and agents framework for building voice and video AI agents, with telephony, observability, and SDKs. The self-hosted framework is free, and LiveKit Cloud includes a free allowance of agent minutes per month. It targets real-time media, which is more than most chatbots need.
Pricing: Free to self-host; LiveKit Cloud has a free tier and paid plans.
Dograh is a BSD-2-Clause voice agent platform where you choose your own speech-to-text, LLM, and text-to-speech models, with a visual workflow builder. It can be self-hosted, used as a managed cloud, or deployed in your own VPC.
Pricing: Free to self-host; the managed cloud is paid.
