Vercel has improved its developer experience by introducing updates for projects that apply to all users on Hobby, Pro, and Enterprise plans. The updates include a new project-level Git system, which allows users to connect multiple GitHub, GitLab, or Bitbucket repositories to individual projects. This feature mainly affects larger teams and agencies. Additionally, Vercel has updated the project creation flow to allow for searching existing repositories, reducing page loads and deployment time. The platform also offers a template library that can be accessed during project creation, featuring advanced templates like Next.js Commerce and Virtual Event Starter Kit.
