Compare two blocks of text and see exactly what changed. Switch between line-level and word-level granularity, side-by-side or unified layout, with added and removed line counts.
Compare configs, Terraform plans, YAML manifests, or any text. See additions, deletions, and unchanged lines with line numbers.
Word-level diffing is the setting people forget exists, and it is the one that matters for prose, config values, and long single-line content like minified JSON or a connection string. Line diff on a one-line change tells you the line changed; word diff tells you which token changed.
One trick: to diff two JSON payloads meaningfully, sort both key sets first in the JSON Formatter. Otherwise key ordering differences produce a diff that is technically correct and completely unreadable.
