Share a Git diff

Turn a raw patch into a clean review link.

Diffdump turns a unified Git diff into an unlisted browser view with syntax highlighting, file navigation, and split or unified layouts. Share links use random URLs, accept patches up to 2 MiB, and expire after 24 hours.

Create a share link

Share a diff from the browser

  1. Open Diffdump and select the diff.patch tab.
  2. Paste a UTF-8 unified diff into the editor.
  3. Create the link, review the rendered patch, and send the URL to your reviewer.

Share a diff from the terminal

Send the working-tree patch with one command. Diffdump returns the new share URL as plain text.

git diff | curl -T- https://diffdump.com/d

On macOS, append | xargs open to open the returned URL immediately.

git diff | curl -T- https://diffdump.com/d | xargs open

What is stored?

Raw shared diffs are stored in a private Cloudflare R2 bucket under a random 96-bit URL slug. Diffdump enforces the 24-hour expiry when the link is read, and the storage lifecycle removes expired objects.

Links are unlisted rather than access-controlled: anyone who has the URL can open the diff. Remove credentials, private keys, and other secrets before sharing.

What can be shared?

  • Working-tree or staged changes from a Git repository.
  • A commit exported as a unified patch.
  • Multi-file .diff and .patch content up to 2 MiB.
  • Agent-generated code changes that need human review.
