Deprecation Timeline

Vercel has announced the official sunset of the now.json configuration file format. Support will be completely removed on March 31st, 2026, giving users over a year to migrate their projects.

Migration Path

Migrating existing projects is straightforward—no complex refactoring required:

• Rename your now.json file to vercel.json
• No content changes are necessary; the configuration syntax remains compatible
• The new filename aligns Vercel's tooling with its current branding and platform evolution

Advanced Configuration

For teams with more complex deployment needs, Vercel offers vercel.ts as a modern alternative that enables programmatic project configuration, providing greater flexibility for sophisticated setups.

Action Items

• Review your projects for any now.json files
• Plan migration to vercel.json before the March 31, 2026 deadline
• Consult the Vercel configuration documentation for detailed setup guidance
