Bonfire Terminal vs Leon: FAQ
Is Leon private?
Leon is fully private when self-hosted, running on-device with local Whisper and no training on your data. Bonfire Terminal matches this local-first stance, keeping everything on the machine, and adds it as a finished product rather than a project to configure.
Is Bonfire Terminal cheaper than Leon?
Leon is free and open-source. Bonfire Terminal is a one-time perpetual license, so it costs more upfront, but there is no subscription and your LLM key is billed at provider cost with no markup, keeping any cloud usage as cheap as possible.
Can Bonfire Terminal replace Leon?
Yes, for most personal-assistant needs. Both are on-device assistants with local voice. Bonfire Terminal adds media processing and messaging bridges and ships as a ready product, while Leon appeals to those who want to build and extend an open-source assistant.
What can Bonfire Terminal do that Leon can't?
Bonfire Terminal adds local media processing and Telegram and WhatsApp bridges, and it is a maintained packaged product. Leon offers local Whisper voice but no messaging bridges or media pipeline out of the box, so Bonfire covers a broader workflow.
How do I switch from Leon to Bonfire Terminal?
Install Bonfire Terminal and add your own LLM key at cost to replace Leon's model configuration. You keep local voice via Whisper and gain media processing and messaging. Keep Leon if you enjoy customizing an open-source assistant with your own skills.
Does Bonfire Terminal work offline vs Leon?
Leon offers partial offline use, running local Whisper and local models without the network. Bonfire Terminal likewise runs its agent, local Whisper, and media processing on-device, needing a connection only when your chosen cloud LLM is called.
