Bonfire Terminal vs Comet
Comet is an open-source ML and LLM observability platform built on a hybrid model, self-hosted for privacy or run as paid cloud. Bonfire Terminal takes a different road: everything stays on your device, you bring your own LLM key at cost with zero markup, and you pay once for a perpetual license.

Bonfire Terminal vs Comet: FAQ
Is Comet private?
Comet can be private when self-hosted, where it runs on your own infrastructure and does not train on your data. Its cloud tier is hybrid, so some data leaves your environment. Bonfire Terminal is local-first by design, keeping everything on your device with no cloud round-trip.
Is Bonfire Terminal cheaper than Comet?
Comet is free when self-hosted but charges a subscription for its cloud tier. Bonfire Terminal is a one-time perpetual license with no recurring fee, and you supply your own LLM key at provider cost with no markup, so ongoing spend stays predictable.
Can Bonfire Terminal replace Comet?
Not directly. Comet specializes in experiment tracking and LLM observability, while Bonfire Terminal is an on-device AI agent and terminal. If your need is a private, key-owned assistant rather than model monitoring, Bonfire fits; for pipeline telemetry, Comet remains purpose-built.
What can Bonfire Terminal do that Comet can't?
Bonfire Terminal runs fully on-device with local Whisper speech recognition, local media processing, and Telegram and WhatsApp bridges. Comet is an observability platform without messaging bridges or on-device voice, so Bonfire covers a private personal-agent workflow Comet does not target.
How do I switch from Comet to Bonfire Terminal?
Because the two serve different purposes, switching means adopting Bonfire Terminal for on-device agent work rather than porting dashboards. Install Bonfire, add your own LLM key at cost, and connect Telegram or WhatsApp. Keep Comet if you still need ML observability alongside it.
Does Bonfire Terminal work offline vs Comet?
Comet offers only partial offline capability and leans on hosted services for full function. Bonfire Terminal is built local-first, so its agent and local media processing run on-device without a connection, needing the network only when your chosen cloud LLM is called.
