We built our own cloud agents runtime. Here's what we learned
posthog.com
PostHog built a cloud “agents runtime” that runs coding agents in cloud sandboxes and uses Temporal to keep agent state, snapshots, and credentials alive even when a VM dies mid-run.
Why it matters
PostHog describes the shared runtime behind its Desktop, Slack, self-driving, and web agents. It’s built around Temporal workflows, VM sandboxes, snapshots, fresh credentials, and resumable run logs—plus hard-won lessons for queued follow-ups and surviving sandbox loss.
