Dev asks for sandbox provider supporting N concurrent sandboxes with dynamically mountable disks

zeeg · x · 2026-10-17

Developer zeeg asks on X whether any sandbox provider supports: N concurrently running sandboxes with disks that can be mounted onto another sandbox (at least 32 at a time), without knowing mount points before startup, and with the ability to vary them throughout the sandbox lifecycle. He wants a parent sandbox plus N children (concurrency capped below N) where children write to a disk point the parent reads — an "N writers, 1 reader" semi-persistent disk setup.
