Vercel Sandbox snapshot creation is now up to 10x faster
Vercel Sandbox snapshot creation is now up to 10x faster, with a median time to snapshot under 0.4 seconds, down from 4.4 seconds. Snapshot restore speed improved 50% at p50, from 500ms to 250ms, via a new indexing approach in the Vercel Hive Snapshot (VHS) format.
Why it matters
Faster snapshots and restores reduce wait time when Sandbox sessions start and stop, which matters for builders running persistent sandboxes. The change applies automatically to new snapshots, while existing snapshots keep the previous format.
Who should care
Developers and teams using Vercel Sandbox for persistent or automated sandbox sessions.
What you can do
Review the Vercel Sandbox snapshots documentation and test session stop and resume times in your own workflows, noting that only new snapshots use the new format.
