- (2023-02-22) Igor Akkerman: Appears to compare the HTML code line by line, as if you put two text editors side by side. Expectation was a smart DOM comparison. Also didn't regognize inserted lines. Downloading the HTML and comparing using any text compare tool did a far better job for me.
- (2021-02-17) Georgii Trofymov: Didn't work for me. For every page I wanted to compare it showed the alert "this page is not supported"
- (2021-02-09) Scott Silliman: I couldn't this to work. all I get is an alert with chinese text in it and a checkbox asking whether to disable further alerts from this extension. when trying to open or diff. perhaps this works, but some instructions please?? totally willing to re-rate if I had instructions.
- (2019-11-20) chris clark: didn't work for me, every page I attempted to use had the message "This page is not supported."
- (2019-05-05) MONO CHROME: Великолепно! Работает на отлично! Удобно!
- (2018-09-24) Ch Ho: It does exactly what it says on the tin: it compares the html in two different tabs, or the current tab with the same page on a test server (regular expression string substitution). The differences are shown side-by-side, like Meld does. I really appreciate that it is self-contained, and doesn't send data to a server owned by the extension developer to do the processing. Wishlist: reloading the same page and alerting when the contents change, and being able to ignore certain strings (like security tokens that change on every reload).
- (2018-01-28) Daniel Moore: Works as described and useful. Wishlist: compare multiple servers at once; add headers (like Host) to request for subset of servers.
- (2017-07-08) y sugano: If you often check the co-worker/out source worker's codes, this extention will be useful tool.
- (2017-06-28) Yutaka Tanino: Very useful for all web developers. You can quickly check differences of web sites' html source.
- (2017-02-08) zyass tak: HTMLソースレベルで差分を比較できるので、 更新の見落としを防げて便利です。
