Dograh pitches open-source self-hostable Vapi alternative

Hot take: this is really an infrastructure control story, not just a nicer UI for voice bots.

• –The strongest angle is provider flexibility: teams can swap telephony, transcription, model, and speech providers without surrendering the whole stack.
• –Built-in tracing and recordings matter because voice systems fail across many hops, and Dograh is leaning into observability as a product feature.
• –Self-hosting plus open source makes it more attractive for teams that care about data control, latency, and deployment constraints.
• –The drag-and-drop workflow builder lowers the barrier to entry, but the long-term appeal will depend on how robust the runtime and integrations are versus hosted incumbents.
