What is on it
Browser
A real browser it drives. Fill in forms, click through dashboards, pull what has no API.
Files
A shared folder you both read and write. Deliverables land here.
Terminal
A full shell. Run code, install packages, drive command-line tools.
Search
Search the web and fetch pages, without opening a browser.
Apps & webserver
Host a live web app at a URL you can visit.
Storage
A managed Postgres database for anything that has to persist.
It keeps working when you stop
The computer is not your laptop, so nothing depends on your laptop staying awake. Close the lid and the agent keeps going: a long build finishes, a routine fires at 3am, a browser session works through a queue. The sandbox sleeps when idle and wakes on demand. Work that must survive a restart goes in the agent’s repo, its files, or storage.Two computers, one job
Some work lives on your machine instead: a repo you have checked out, a dev server onlocalhost, a tool only installed locally. Portal is the bridge. The agent reads what it needs from your machine, then moves the work up to its own computer and carries on.
Sizes
How much machine an agent gets, and how it asks for more.
Network controls
What the computer can reach on the internet, and how that is governed.
