MIST

Free browser games, a game library and friends — launched from one bookmark.

On a computer or Chromebook

Show your bookmarks bar: Ctrl + Shift + B (⌘ + Shift + B on Mac).
Drag this button up onto the bookmarks bar:

Then go to any normal website and click Mist in your bookmarks bar.

Can't drag? Add it by hand

Copy the code below.
Create a new bookmark (right-click the bookmarks bar → Add page…).
Name it Mist and paste the code into the URL box.

javascript:(()=>{let w=open('about:blank','_blank');if(!w)return alert('Allow pop-ups for this site, then click the bookmark again.');let d=w.document;d.write('<title>Mist</title><body id="el-blank" style="margin:0;background:#1b1b1b;color:#ccc;font:15px sans-serif;padding:24px">Loading…</body>');d.close();fetch('https://raw.githubusercontent.com/th3nu8/EaglercraftLauncher/main/loader.js?'+Date.now()).then(r=>{if(!r.ok)throw 'HTTP '+r.status;return r.text()}).then(c=>{let s=d.createElement('script');s.textContent=c;d.body.appendChild(s)}).catch(e=>{d.body.textContent='Could not load the launcher ('+e+'). This site may block it, so try the bookmark on a different page.'})})()

Good to know

If nothing happens, allow pop-ups for the site you're on and click it again.
Some sites (Google, GitHub) block bookmarklets. Try it on a simpler page.
Bookmarklets don't run on the browser's new-tab page.
