Best fit
Best for developers who browse open-source repositories, review PRs, and triage issues on GitHub in Chrome or Firefox.
On-screen walkthrough
How this looks on a real webpage.
Instead of switching tabs and rebuilding context, highlight the exact passage that slowed you down and press your shortcut (default: Ctrl+Shift+X or Cmd+Shift+X on macOS, fully customizable in settings).
1. Highlighted on page (GitHub Pull Request Diff — Worker Cache Middleware)
+ headers.set('Cache-Control', 'public, max-age=3600, s-maxage=86400') + headers.set('Vary', 'Accept, Authorization')
Ctrl+Shift+X“Is setting `public` alongside `Vary: Authorization` safe on shared CDN caches?”
2. Vezz me on-screen answer overlay
**Watch out:** Under HTTP caching specs (RFC 9111), a response to a request containing an `Authorization` header must NOT be stored by a shared CDN cache unless explicit shared-cache directives (`public` / `s-maxage`) are present—which you just added! However, varying on `Authorization` across thousands of unique bearer tokens destroys CDN cache hit ratios and can risk edge misconfiguration leaks if a proxy strips `Vary`. If the response is user-specific, use `Cache-Control: private, no-store` instead.
3. Suggested follow-up questions in thread
- “What should the header be if we only want to vary on `Accept: text/markdown` for public pages?”
- “Write a concise PR review comment explaining this risk to the author.”
Step-by-step workflow
How to run this workflow in place.
Press your shortcut (no clash with GitHub hotkeys)
GitHub uses single-key shortcuts (`t`, `s`, `l`, `b`), so Vezz me's default `Ctrl+Shift+X` / `Cmd+Shift+X` chord (or your own custom shortcut configured in settings) triggers cleanly every time.
Copy review notes straight into your PR comment
Use one-click copy to paste edge-case questions or explanations into your GitHub review.

Frequently asked questions
Common questions about platform guide — github.
Does Vezz me require connecting my GitHub account via OAuth?
No. Vezz me never asks for GitHub OAuth access or repo tokens. It works purely on the text you highlight inside your browser tab.
Does it break GitHub's split diff layout?
No. Unlike sidebar extensions that steal 400px of horizontal width and crush split diffs, Vezz me opens a compact floating overlay that you can drag anywhere or dismiss with one click.
