SingleFileの拡張機能版を試しました．
ウェブ閲覧中には便利ですが，ヘッドレスでも使いたいのでCLI版を試してみました．
いくつかの選択肢がありますが，今回は地番お手軽そうなDocker Hubのイメージで試してみました．

同じページを一旦ローカルに保存して試してみました．
保存したパスをrootにしてhttpdを起動
$ python3 -m http.server --bind 172.17.0.1 --directory ~/Downloads/
SingleFileで保存
$ time docker run singlefile http://172.17.0.1:8000/gildas-lormeau_SingleFile_%20Web%20Extension%20for%20Firefox_Chrome_MS%20Edge%20and%20CLI%20tool%20to%20save%20a%20faithful%20copy%20of%20an%20entire%20web%20page%20in%20a%20single%20HTML%20file.html > /tmp/sample.html real 0m47.339s user 0m0.059s sys 0m0.110s
思ったより変わらなかったです．
