Vercel Sandbox creation now returns a ready sandbox
Vercel published a changelog entry titled "Vercel Sandbox creation now returns a ready sandbox." The entry states that Sandbox creation now returns a ready sandbox, meaning the create call resolves with a sandbox that is ready rather than one that is still being prepared. The changelog is attributed to Vercel and is dated 2026-10-08T06:00:00.000Z. The supplied source text does not include additional specifics beyond the title and the statement that creation now returns a ready sandbox. It does not describe API signatures, SDK versions, configuration options, timeouts, regional availability, pricing, or migration steps, and none of those details should be assumed from this excerpt. The only source-grounded change is the behavior of the Sandbox creation call: it now returns a ready sandbox.
Developers calling Vercel Sandbox creation now receive a ready sandbox from the create call, per the changelog.
