Bonfire Terminal vs Vapi: FAQ
Is Vapi private?
Vapi states it does not train on user data and offers no key markup, but it is cloud-hosted, so voice runs on its infrastructure. Bonfire Terminal keeps everything on-device with nothing leaving the machine, scoring 93/100 for sovereignty.
Is Bonfire Terminal cheaper than Vapi?
Vapi charges from about $0.05 per minute with no key markup, cheap per call. Bonfire Terminal is a one-time perpetual license, so for steady personal use it avoids per-minute charges entirely after the single purchase.
Can Bonfire Terminal replace Vapi?
Not for building phone voice agents. Vapi is a cloud voice platform for telephony at scale. Bonfire Terminal is a personal sovereign terminal, so it replaces private AI tasks, not a per-minute voice-calling service.
What can Bonfire Terminal do that Vapi can't?
Bonfire Terminal runs offline, keeps data on-device, transcribes with local Whisper at no per-minute cost, processes media locally, and bridges Telegram and WhatsApp. Vapi is a cloud voice service, though it also offers Whisper as one option.
How do I switch from Vapi to Bonfire Terminal?
Switch if you wanted private AI rather than phone bots. Install Bonfire Terminal, bring the same OpenAI, Anthropic, or Google key with no markup, and run on-device with local Whisper instead of Vapi's cloud voice.
Does Bonfire Terminal work offline vs Vapi?
Bonfire Terminal works offline with local Whisper and models. Vapi has no offline capability because it is cloud-hosted, so its voice agents require connectivity while Bonfire runs entirely on your device.
