experimentalwe recommend trying it on experimental workloads, not production projects or real data.
how it works
- syncup uploads your working directory into a fresh Vercel Sandbox, and keeps it in sync as you edit.
- runinside the sandbox it detects your framework, installs dependencies, and starts your dev server.
- sharethat running dev server is proxied out to a public url anyone can open.
- resumestop it and the sandbox saves a snapshot; the next
up .restores it, files and installed deps in place, instead of starting over.
that last step is Vercel Sandbox persistence, now generally available.
