TinaCMS is a headless CMS that allows content to be stored in files such as Markdown, MDX, JSON, and more, while staying in-sync with the user's Git repository. The platform aims to provide a seamless experience for both developers and marketers by integrating Visual Editing capabilities, making it easier for users to work on branches and collaborate. With Vercel Preview Deployments, TinaCMS allows users to click-to-edit content without leaving the page, providing a more efficient workflow that balances developer productivity with marketer's needs. The integration also enables incremental static regeneration, server-side rendering, and version control for content, making it an attractive option for large documentation and marketing sites.
