Split-tgz is now the default CLI archive deployment behavior
By Steven Van ·
Plain --archive=tgz now gets the faster uploads that split-tgz offered, and the separate split-tgz flag is deprecated.
The separate split-tgz archive option for the Vercel CLI is deprecated. Vercel has made its behaviour the default for tgz, after confirming it is stable.
Archive deployments are meant for large projects with thousands of files deployed from the CLI. vercel deploy --archive=split-tgz was released earlier as its own option, with up to 30% faster uploads and no file upload size limits. Those benefits now come with plain --archive=tgz, so nothing needs to change in the command.
The CLI docs add a caveat: archiving can make some deployments slower, because it negates the caching of source files that speeds up later uploads.
