Bonfire Terminal vs PromethAI Backend
PromethAI Backend is an open-source, hybrid RAG knowledge backend, free as OSS and fully private when self-hosted, with pay-per-token billing and no markup across OpenAI or any provider. Bonfire Terminal is a finished sovereign on-device agent rather than a backend, with BYO-key billing at cost and a one-time perpetual license.

Bonfire Terminal vs PromethAI Backend: FAQ
Is PromethAI Backend private?
Self-hosted, PromethAI Backend is open source and fully private, though its hybrid architecture can reach cloud providers. Bonfire Terminal is local-first by default, keeping prompts, documents, speech, and media on-device so nothing leaves your machine automatically.
Is Bonfire Terminal cheaper than PromethAI Backend?
PromethAI Backend is free open source with pay-per-token usage and no markup. Bonfire Terminal is a one-time perpetual license with BYO-key billing at cost. Both avoid markup; Bonfire gives you a finished product rather than a backend you must build on.
Can Bonfire Terminal replace PromethAI Backend?
For end users, yes. Bonfire Terminal delivers working RAG-style knowledge on-device without engineering. PromethAI Backend is developer infrastructure you integrate into an application, so it suits builders rather than direct personal use like Bonfire.
What can Bonfire Terminal do that PromethAI Backend can't?
Bonfire Terminal ships local Whisper speech recognition, local media processing, Telegram and WhatsApp bridges, and a one-time license as a complete product. PromethAI Backend is a RAG backend and does not package these user-facing speech, media, or messaging features.
How do I switch from PromethAI Backend to Bonfire Terminal?
Reuse your OpenAI key, since both support it. Rather than integrating a backend, install Bonfire Terminal, connect your key at cost, and use a finished on-device knowledge agent with speech and media under a single perpetual license.
Does Bonfire Terminal work offline vs PromethAI Backend?
Bonfire Terminal runs fully offline with a local model across knowledge, speech, and media tasks. PromethAI Backend offers only partial offline capability and depends on chosen providers, so it commonly needs cloud connectivity to operate.
