Nautilo (by AgentSea)

Nautilo is a self-hosted, multi-user AI "Genie" harness from AgentSea, aimed at small teams and operators who want to run their own agent workspace instead of renting one. It provides a platform where users can interact with their Genies and collaborate across desktop, mobile, and web, with the full stack shipped as open source under the MIT license. The launch matters because most agent products today lock a single user into a single vendor chat window, and Nautilo is trying to make agents a shared surface that a whole organization can operate on its own infrastructure. Each person gets their own Genie, described on the site as a customizable agent with a personality, memory, face, and voice, that can write, research, browse, coordinate coding agents, or help make a film. The design is built around Rooms where people and their Genies share one conversation, so a colleague's Genie can join a thread, take on a document, and bring an answer back without the usual @-mention choreography. Operators can start locally with Docker, deploy on Railway or Docker Compose, and connect through native Mac, iPhone, and Android clients or a web client tied to their server. Nautilo is built by the team at Kentauros AI, which develops the AgentSea stack. According to the company's org chart, the co-founders are Daniel Jeffries, President and co-founder, Mariya Davydova, Chief Operating Officer and co-founder, and Patrick Barker, Chief Technology Officer and co-founder . Jeffries, who announced the launch, is also the managing director of the AI Infrastructure Alliance and previously held a senior role at Stability AI, which gives some context for why this group is pushing an openly licensed, self-hostable alternative rather than a hosted SaaS.
