Your own super agent. Your people and their Genies. You own the intelligence.

Meet your Genie. Give her a personality, memory, face, and voice. Write, research, and make things together. Bring your people and their Genies into the same Room. Your server. Your models. Your rules. Open source. MIT licensed.

Get started

Your first Nautilo. From an empty server to something you made together.

Try it locally on your Mac →

Meet your Genie, make her yours, and create your first document together. Follow the illustrated guide.

You'll need Docker Desktop and a model API key. Nautilo is in alpha.

For your team: Deploy to your datacenter or VPS →

Already have a server? Download Desktop for Mac → · Download Mobile →

Bring your people. Bring their Genies.

Bring your people and their Genies into the same Room. Pull an idea apart, write the first draft, send a Genie off to research the missing piece. Give yours a personality you want to spend time with.

Then grab the controls. Rewrite the paragraph. Move the lettering. You shouldn’t need a better prompt to move a word three inches to the left.

And keep the keys to your own house. You choose the models, run the server, and decide who gets access. Sharing a Room shouldn’t mean handing over your whole life.

This monorepo contains the applications and shared packages that make Nautilo work. Follow the links straight to the part you want to understand or change.

Applications

Application	Role
Workbench	The shared browser UI, also used inside Desktop.
Desktop	Electron client, local workstation integration, and packaging.
Mobile	The React Native / Expo mobile client.
CLI	Server deployment and administration from the terminal.

For deployment and maintenance, see deploy, the Compose driver, packaging, and operations. The application bridge explains how Genies interact with application surfaces.

Develop from source

The checkout pins Bun 1.4.4 and Node 24.22.1. Install Docker for local PostgreSQL and Logto infrastructure. Desktop preparation may also need Rust for its native helper.

git clone https://github.com/agentsea/nautilo.git
cd nautilo
bun install --frozen-lockfile
bun run dev-stack --instance my-nautilo-dev

Choose an unused instance name for a fresh environment. Keep that terminal running, then follow the source development guide to claim the instance, configure a model, and connect a client. That guide also covers existing instances, isolated clones, and Desktop profiles.

Before submitting a code change, run the checks appropriate to it. The standard repository checkpoint is:

bun run lint
bun run typecheck
bun run test:unit
bun run lint:unused

See the testing guide for focused checks and integration requirements. Coding assistants should read AGENTS.md and README.ai before editing.

Help build it

There is an enormous amount left to invent. Bring the thing you understand better than anyone: the ugly workflow you've fought for years, the design detail that keeps bothering you, the bug you refused to walk away from. We want that judgment in the project.

Small corrections are welcome. For larger changes, start with the problem and agree on the design before building. A mountain of generated code won't make a confused idea clearer. A well-understood problem gives us somewhere to go.
