Summary
On July 3, 2026, Vercel added FUSE support to Vercel Sandbox, its isolated environment for running untrusted or AI-generated code, letting workloads mount remote storage such as S3 buckets, network filesystems, or any FUSE-compatible driver as a regular path inside a running sandbox.
What changed
Vercel Sandbox now supports FUSE (Filesystem in Userspace), letting users mount remote storage such as S3 buckets, network filesystems, or any FUSE-compatible driver as a normal path inside a running sandbox without copying data in first.
Why it matters
It lets agent platforms stream large datasets directly from object storage, share state across sandboxes through a common filesystem, or run POSIX-expecting tools against remote sources without inflating startup time or storage, which is useful for coding agents that need large repos or datasets on demand. It deepens Vercel Sandbox's role as execution infrastructure for AI SDK agents.
