dograh-hq/dograh is an open-source voice agent platform that hit GitHub trending on 2026-05-17 with +236 stars in 24 hours (1,508 total). The framing is direct: 'open-source alternative to Vapi.' Build voice AI agents through a drag-and-drop workflow builder, deploy on your own infrastructure in roughly 2 minutes, and own the full code path end-to-end. The bet is that the voice-agent vertical follows the same self-hostable pattern that played out in chat agents — vendor-managed platforms first, then open-source equivalents once the architecture stabilizes. dograh fits the moment cleanly: voice-agent infrastructure is maturing, the operator playbook for production voice calls is becoming legible, and teams that don't want to route customer-facing calls through a hosted SaaS now have a credible self-hosted option.
dograh is an open-source voice agent platform from dograh-hq, positioned explicitly as the self-hostable alternative to Vapi. It crossed 1,508 GitHub stars on 2026-05-17 with +236 stars in 24 hours — landing on the trending board alongside the agent-runtime category surge of the same day. The pitch is direct: drag-and-drop voice workflow builder, 2-minute deploy, 100% open source.
dograh ships a visual workflow builder for designing voice agent call flows — conditional branching, telephony integration, transcription, response generation. The output is a deployable voice-agent runtime that handles concurrent calls and can be hosted on standard cloud infrastructure. The mental model maps closely to Vapi’s hosted platform, which makes the migration path obvious for teams already operating on Vapi who want to repatriate the workload.
Voice agents are the vertical where the open-source vs hosted-platform tension is sharpest right now. Customer-facing calls have stricter compliance, latency, and data-residency requirements than text chat — and many enterprise buyers are reluctant to route those calls through a multi-tenant SaaS. dograh’s 2026-05-17 trending position suggests the open-source self-hosted option is finding real demand. As a category, voice agents are following the same trajectory text chat did 18 months earlier.
