Bonfire Terminal vs Sider
Sider is a cloud-hosted LLM chat UI with about 4M users, freemium from free to $8-$25/mo, using OpenAI, Anthropic and Google with an unstated data policy and API markup. Bonfire Terminal is a sovereign on-device agent instead: it keeps chats local, passes your own key through at cost with no markup, and licenses once.

Bonfire Terminal vs Sider: FAQ
Is Sider private?
Sider's data policy is unstated in the available data, and it is cloud-hosted, so your chats pass through its servers. Bonfire Terminal removes that uncertainty by running on your device, so your conversations never leave your machine.
Is Bonfire Terminal cheaper than Sider?
Sider charges a recurring subscription of $8-$25/mo and applies markup on API usage. Bonfire Terminal is a one-time perpetual license and passes your own key through at cost with no markup, avoiding both the subscription and the added margin.
Can Bonfire Terminal replace Sider?
For multi-model chat and agent tasks, yes, since Bonfire also supports whichever key you bring across providers. Sider offers a handy in-browser sidebar UI; Bonfire trades that browser convenience for full on-device privacy and no subscription or markup.
What can Bonfire Terminal do that Sider can't?
Bonfire Terminal runs offline on-device, transcribes with local Whisper, processes media locally, bridges to Telegram and WhatsApp, and passes your key at cost with no markup. Sider is cloud-only with an unstated data policy, API markup, and no offline mode.
How do I switch from Sider to Bonfire Terminal?
Install Bonfire Terminal and add your preferred OpenAI, Anthropic or Google key. Because Bonfire runs locally, there is nothing to export; you simply move your chat and agent tasks onto your device at cost with no markup.
Does Bonfire Terminal work offline vs Sider?
Yes for local features. Bonfire Terminal's on-device speech and media processing run without internet, and only external model calls need connectivity. Sider is cloud-hosted with no offline capability, so it cannot chat while disconnected.
