DiffsHub handles massive GitHub diffs without lag

DiffsHub is a high-performance code viewer that renders million-line GitHub diffs instantly without browser lag. By simply swapping "github.com" for "diffshub.com" in any URL, developers access a virtualized interface optimized for large-scale reviews.

// ANALYSIS

GitHub's native diff viewer often fails on massive PRs, forcing developers to resort to local checkouts for complex reviews. DiffsHub bridges this gap with a virtualized rendering engine that maintains responsiveness even during comparisons as large as the Linux kernel.

–Leverages open-source Pierre "CodeView" technology for smooth, lag-free scrolling.
–Low-friction URL manipulation allows for instant transitions from GitHub to DiffsHub.
–Eliminates "Too Many Changes" errors that frequently block web-based reviews.
–Local-first architecture prioritizes speed and reliability for complex refactors.
–Companion browser extension enables one-click access to high-performance diffs.
