Paste two versions of TypeScript code to compare additions, removals and edited lines with TypeScript syntax highlighting. The diff runs locally in your browser.

Texto original

Texto modificado

TypeScript syntax locked

This page automatically highlights TypeScript tokens, so you do not need to pick a language before comparing files.

Private local compare

The diff runs in your browser. Source code, API payloads and configuration files are not uploaded to a server.

Split or unified review

Use split view for side-by-side review, unified view for compact patches, and hide unchanged lines for large files.

Compare TypeScript files online

This TypeScript diff checker is built for developers who need a fast, private way to compare code and configuration changes. Paste two versions, run the comparison, and review additions, removals and inline edits with TypeScript syntax highlighting already enabled.

  1. Paste or upload the original TypeScript file on the left.

  2. Paste or upload the changed TypeScript file on the right.

  3. Compare the result in split or unified view, then hide unchanged lines when you only need the edited regions.

Private browser-based TypeScript comparison

The diff runs locally in your browser, which keeps source code, API responses, secrets and configuration files on your device. One recent session may be stored in your browser storage for restore, and you can clear it from the tool at any time.

Common TypeScript diff workflows

Compare interfaces, types and React component changes.

Review API contract updates before merging.

Check strictness, generic and import edits.

TypeScript syntax highlighting

Highlighting is locked to TypeScript on this page, so the language selector stays out of the way. The parser focuses on tokens such as types, interfaces, generics, imports while the diff engine highlights the actual text changes.

.ts, .tsx, .mts, .cts

TypeScript diff checker FAQ

What is a TypeScript diff checker?

A TypeScript diff checker compares two versions of TypeScript content and highlights added, removed and edited lines. This page locks syntax highlighting to TypeScript, so language tokens are easier to scan while reviewing changes.

Does this TypeScript diff tool upload my code?

No. The comparison runs in your browser. Your TypeScript files are not uploaded to a server when you click Compare.

Which TypeScript file types can I compare?

You can paste or upload plain-text files such as .ts, .tsx, .mts, .cts. Any text file can be compared, but this page highlights TypeScript syntax automatically.

Can I compare large TypeScript files?

Yes. Large comparisons run in a background worker so the browser stays responsive. Very large files may still take a few seconds on your device.
