Cloud Computer
Explore your Nebula Device's full computing environment — persistent filesystem, code execution, browser control, and live server hosting for your agents.
Your Nebula Device is a full cloud computer — not a sandboxed or restricted environment. It has a real filesystem, a code execution environment, a browser agents can control, and the ability to host live servers.
Filesystem
Agents have access to a persistent filesystem on your Device at /home/sprite. Files written here survive between conversations and sessions.
What agents can do with the filesystem:
Read and write files in any format — text, CSV, JSON, images, audio, video, and more.
Create, move, rename, and delete files and folders.
Search file contents and find files by name or pattern.
Store outputs from code runs, downloaded data, and generated artifacts.
Files you share in chat are automatically available in the filesystem. The filesystem is shared between you and all of your agents — files an agent writes are files you can download, and files you upload are immediately available to any agent.
Code execution
Agents can run code directly on your Device in a real programming environment with network access and the ability to install packages.
Supported languages and environments:
pandas, numpy, matplotlib, scikit-learn, httpx, and more pre-installed.
Full shell access for scripting, CLI tools, and system commands.
ESM imports and top-level await support.
pip, npm, and other package managers work normally.
This enables data analysis on real files, building and running projects end-to-end, generating charts and reports, and deploying custom tools your agents can use in future conversations.
Server hosting
Agents can start and run live servers on your Device — web servers, APIs, databases, or any process that listens on a port. Nebula automatically exposes these via a public URL so you (or anyone you share the link with) can access them directly.
Use cases:
An agent builds a web app or dashboard and gives you a URL to view and interact with it in real time.
Spin up a local API server that other agents or external services can call.
Run a database on your Device and keep it live between sessions for agents to query on demand.
Launch a staging version of a site or tool for you to review before deploying elsewhere.
Servers keep running as long as your Device is on — which is always.
Computer use
Agents can control a full browser on your Device, enabling them to interact with websites and web apps the same way a human would.
Click buttons, fill out forms, and submit data on any web page.
Take screenshots of any page for review or documentation.
Run multi-step browser workflows — log in, navigate to a report, download a file, and more.
This is especially useful for tasks that don't have an API — if a human can do it in a browser, an agent can too.
Hardware specs
Your Device runs on dedicated hardware sized for real workloads:
| Resource | Spec |
