Turn a raw patch into a clean review link.

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.

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

Raw shared diffs are stored in a private Cloudflare R2 bucket under a random 96-bit URL slug. Each request checks the stored expiration time, so links stop working after 24 hours. An R2 lifecycle rule deletes the expired objects afterward.

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.

Terminal uploads can include a GitHub repository and full base commit SHA. When a reviewer expands collapsed context, their browser fetches the base file directly from GitHub and applies the shared patch locally. Public repositories work anonymously; private repositories use the reviewer’s locally saved GitHub token. core.quotepath=off keeps non-ASCII file paths literal in the patch so their context stays expandable.

BASE_SHA=$(git rev-parse HEAD)
git -c core.quotepath=off diff --full-index --binary "$BASE_SHA" |
  curl -T- \
    -H "X-Diffdump-GitHub-Repo: org/repository" \
    -H "X-Diffdump-Base-Sha: $BASE_SHA" \
