Should you buy it? If unlimited email accounts on paid plans is your top priority and you can absorb the cost and learning curve, Instantly.ai delivers real value. But before you commit, read the section below.
A different approach: Bonfire Terminal
Instantly.ai runs in the vendor's cloud — your data is processed on their servers, and you pay every month for as long as you use it. Bonfire Terminal is a different kind of tool: an AI agent that runs as a desktop app on your own machine. No cloud, no API credits, and nothing you type leaves your computer.
To be straight with you: it is not a drop-in replacement for Instantly.ai, and we are not going to pretend it is — they do different jobs. It is worth a look if the cloud-subscription model itself is what you want out of, or if you want an AI agent that works privately and offline. If Instantly.ai is doing its job for you, keep it.
