Text Diff API
Compare two pieces of text and get a precise, structured diff. Choose line, word or character granularity for a full edit script (equal, inserted, deleted) with addition and deletion counts, get a compact inline word diff, or render a standard unified diff (patch) with configurable context lines and file labels — ready to feed into patch tooling or a code-review UI. Built on a Longest-Common-Subsequence algorithm for accurate, minimal diffs. Every endpoint works by GET or JSON POST and runs entirely server-side with no third-party upstream, so responses are instant and the service is always available. Ideal for code review and version tooling, CMS and document editors, change tracking, plagiarism highlighting and content audits.
