Vercel Sandbox Persistence Is Now GA — Filesystem State Auto-Saved and Restored Between Sessions

Vercel Blog·medium signal

Vercel Sandboxes now automatically save and restore filesystem state between sessions with no manual snapshot management. Each sandbox gets durable storage, making stateful AI agent workflows and development environments persistent by default. For builders using Vercel's AI SDK or hosting agent-based applications, this removes the biggest friction point: agents no longer lose context between invocations.
