Bonfire Terminal vs Mastra: FAQ
Is Mastra private?
Mastra is private when self-hosted, being open source and running in your own app; its cloud is vendor-managed and speech depends on chosen providers. Bonfire Terminal is local-first with on-device Whisper, keeping data and your BYO provider key on-device.
Is Bonfire Terminal cheaper than Mastra?
Mastra is free to self-host but bills pay-per-token and offers paid cloud, plus developer time. Bonfire Terminal is a one-time perpetual license, with LLM usage through your own key at raw provider cost, no markup or subscription.
Can Bonfire Terminal replace Mastra?
For end users, yes; for developers building custom agents in TypeScript, not directly. Mastra is a framework. Bonfire Terminal is a ready sovereign agent, so if you want the finished experience rather than the toolkit, it replaces the need.
What can Bonfire Terminal do that Mastra can't?
Bonfire Terminal ships Telegram and WhatsApp bridges, local Whisper speech, and local media processing as a finished agent. Mastra is a framework whose speech is configurable via external providers and offers no built-in messaging bridges.
How do I switch from Mastra to Bonfire Terminal?
If you built an agent with Mastra to serve yourself, install Bonfire Terminal and add any provider key. Bonfire handles orchestration internally, so you use it directly rather than maintaining framework code.
Does Bonfire Terminal work offline vs Mastra?
Mastra is partially offline-capable depending on your provider setup. Bonfire Terminal is local-first, running its agent, on-device Whisper speech, and media processing locally, so its core features keep working offline when configured with a local model.
