TinaCMS connects visual editing with content stored in files and Git. A replacement should be tested with an editor who does not use the command line.
Create a sample page with an image, structured fields, and a rich-text section. Ask the editor to fix a sentence, preview it, submit it for review, and roll it back after publication. Inspect the resulting file diff, Git history, media path, and whether a developer can merge a simultaneous code change without conflict. Repeat with an unpublished draft.
Tina's editor guide describes the preview and save workflow. Define who owns publishing and schema changes before migrating; an attractive editor is not enough if changes bypass the review process you rely on.
