Thoughts:<p>I like the look. Very clean. I like how fast it's responding; better than archive.org (though, obviously, they have different scaling problems).<p>"Your own internet archive" might be overselling it, as other commenters have pointed out; the "Your" feels a bit misleading. I think "Save a copy of any webpage." gives a better impression, which you use on the site itself.<p>The "Archive!" link probably shouldn't work if there's nothing in the URL box. It just gives me an archive link that errors. Example: [1]<p>Using it on news.YC as a test gave me errors with the CSS & JS [2]. This might be due to the fact that HN uses query parameters in their CSS and JS, which repeat in the tesoro URL, which you may not be parsing correctly.<p>Maybe have something in addition to an email link for submitting error reports like the above, just cause I'd be more likely to file a GitHub issue (even if the repo is empty) than send a stranger an email.<p>As other commenters have pointed out, archive.is also does this, and their longevity helps me feel confident that they'll still be around. Perhaps, if you wish to differentiate, offer some way for me to "own" the copy of the page, like downloading it or emailing it to myself or sharing it with another site (like Google Docs or Imgur) to leverage redundancy, or something like that. Just a thought.<p>All in all, nice Show HN.<p>EDIT: You also may want to adjust the header to work properly on mobile devices. Still though, nice job. Sorry if I'm sounding critical.<p>[1] <a href="https://archive.tesoro.io/320b55cc9b78e271c94716ee23554da8" rel="nofollow">https://archive.tesoro.io/320b55cc9b78e271c94716ee23554da8</a><p>[2] <a href="https://archive.tesoro.io/a7bf03e247224bc3b4e5a7c1f2ad42b1" rel="nofollow">https://archive.tesoro.io/a7bf03e247224bc3b4e5a7c1f2ad42b1</a>
