Bonfire Terminal vs Heym: FAQ
Is Heym private?
When self-hosted, Heym is open source and fully private, though its hybrid architecture may reach cloud providers depending on configuration. Bonfire Terminal is local-first out of the box, keeping prompts, speech, and media processing on-device without any setup work required.
Is Bonfire Terminal cheaper than Heym?
Heym is free to self-host as open source. Bonfire Terminal is a one-time perpetual license with bring-your-own-key billing at cost. Heym's software is free but you host and maintain it; Bonfire trades one payment for a supported, finished product.
Can Bonfire Terminal replace Heym?
For most users, yes. Bonfire Terminal gives you working agent capabilities without framework engineering. Heym suits developers who want to construct and customize agents themselves, whereas Bonfire delivers a turnkey on-device agent with speech and media built in.
What can Bonfire Terminal do that Heym can't?
Bonfire Terminal ships local Whisper speech recognition, local media processing, WhatsApp and Telegram bridges, and a one-time license as a complete product. Heym is a framework you build on and does not include packaged local speech or media features.
How do I switch from Heym to Bonfire Terminal?
Reuse your existing OpenAI or Anthropic keys, since both tools support them. Instead of maintaining Heym's framework code, install Bonfire Terminal, connect your key at cost, and your agent runs on-device immediately with no deployment overhead.
Does Bonfire Terminal work offline vs Heym?
Bonfire Terminal runs fully offline with a local model across agent, speech, and media tasks. Heym offers only partial offline capability and depends on chosen providers and hosting, so it commonly relies on cloud connectivity in practice.
