I've published Smart Node under the AGPL-3.0 licence. It runs a crew of AI agents for the front office of a small business: answering messages, following up on leads, booking appointments, keeping the paperwork in order. Anything that commits the business, a quote, a booking, a message to a client, waits for the owner's approval.
It runs on a machine you control, so customer data stays with you. Models are reached through one gateway: Claude, GPT, Gemini, or a model server of your own. It ships with 50 ready crews and 95 roles in 17 departments, and needs Debian or Ubuntu with 2 GB of memory.
