Editorial interest 79/100 Selection signal · not a rating of the site

Quartz offers an invite-only cloud computer where coding agents can work on tasks and return pull requests for review.

Landing page captured for the 2026-10-16 issue.

For: Developers who delegate coding tasks to AI agents
Worth noticing: Its onboarding separates GitHub identity from repository access; the page says agent credentials stay in an encrypted vault on the machine.

Field notes

The onboarding separates GitHub identity from repository access, and the page says agent credentials stay in an encrypted vault on the machine rather than Quartz servers. Each task gets an isolated sandbox and branch; follow-ups are described as resuming the same agent session and working copy. Quartz is marked private alpha and invite-only, so the displayed workflow is product evidence from its homepage, not independent confirmation of service operation.
