> Review large Git diffs while tracking what you have inspected

seendiff is a local code-diff viewer with separate indicators for content that has been seen and explicitly reviewed. It opens a browser interface from a Git repository and can compare against a chosen branch, tag, or commit. Keyboard controls, search, a minimap, and side-by-side or unified views help reviewers navigate large changes.

Review progress persists across closing the window and common history changes such as rebasing or amending. A walkthrough mode lets a coding agent explain its work directly alongside the diff, giving a human reviewer more context. The project is free and open source, requires Git and Python 3.10 or later, and runs through localhost. Automatic visibility tracking records that a block appeared on screen, not that it was understood.
