Every sandbox is its own island
Its own VM and kernel. Nothing leaks between them.
Or open a shell in the browser
See every sandbox and open a terminal in any of them.
Questions
Anything else, ask when you join the waitlist.
Is it safe to run code I don't trust?
Yes. Each sandbox runs in its own virtual machine with its own kernel, so a bad package or a broken script can't see your other sandboxes or anyone else's.
What can code inside a sandbox reach?
The public internet, so pip install and git clone work. It
can't reach other sandboxes, the machine it runs on, private networks or outbound mail
on port 25.
How long can a sandbox run?
Five minutes by default and up to 24 hours. Call setTimeout to give it
more time while it runs. When the time is up, it's deleted with its files.
Which languages can I use?
Anything that runs on Linux can run inside a sandbox. To control sandboxes there is a TypeScript SDK today, plus a REST API for creating and deleting them.
