Bonfire Terminal vs Letta: FAQ
Is Letta private?
Letta is private when self-hosted, being open source with local-model support; its cloud is vendor-managed. Bonfire Terminal is local-first as a finished agent, keeping your data and BYO provider key on your own device by default.
Is Bonfire Terminal cheaper than Letta?
Letta is free to self-host with subscription cloud pricing. Bonfire Terminal is a one-time perpetual license with no recurring fees, and any LLM usage runs through your own key at raw provider cost with no markup added.
Can Bonfire Terminal replace Letta?
For users wanting a working agent rather than a framework, yes. Letta specializes in stateful memory for agents you build. Bonfire Terminal ships as a complete sovereign agent you use immediately, without assembling memory infrastructure yourself.
What can Bonfire Terminal do that Letta can't?
Bonfire Terminal ships Telegram and WhatsApp bridges, local Whisper speech, and local media processing as a finished agent. Letta is a memory-focused framework and offers no built-in messaging bridges, speech engine, or media handling.
How do I switch from Letta to Bonfire Terminal?
If you built a stateful agent with Letta to serve yourself, install Bonfire Terminal and add any provider key or local model. Bonfire handles orchestration internally, so you use it directly rather than maintaining framework code.
Does Bonfire Terminal work offline vs Letta?
Letta is partially offline-capable with local models. Bonfire Terminal is likewise local-first, running its agent, Whisper speech, and media processing on-device, so its core features keep working offline when configured with a local model.
