Support for now.json will be removed on March 31, 2026
By Steven Van ·
now.json support ends March 31, 2026; existing files just need renaming to vercel.json.
Vercel will drop support for the legacy now.json configuration file on March 31, 2026. Projects still using it can migrate by renaming the file to vercel.json, since no other content changes are needed. For programmatic configuration, Vercel points to vercel.ts as an alternative; more detail is in the project configuration documentation.
Vercel
The platform for frontend developers — deploy, preview, and scale web apps and AI agents with zero config.
