How it works GitHub Run for free

Your agents keep
working — even when
your machine doesn't.

An isolated cloud environment for every feature. Run coding agents in parallel — one session per fix — free on your own machine, Cloud the moment your machine can't carry it.

Every session is a full workspace.

Terminals, code, files and live previews — arranged in layouts you define once. This one is real: switch layouts, click views.

What did shipping
this thing cost?

Codespaces bills per seat. Agent tools bill per token in an undifferentiated pile. We attribute every cent — agent + infra — to the feature itself.
