If you spend a lot of time working in HubSpot, you've probably run into that frustrating moment: you make a change, hit save, refresh the page... and nothing. Your updates aren’t showing up! This usually happens because HubSpot (to keep things fast) serves pages from its cache — which means your edits don’t always appear right away. And while a hard refresh (Ctrl+Shift+R or Cmd+Shift+R) can clear your browser cache, it won’t always get around HubSpot’s own caching layer.
That’s where the cachebuster trick comes in. By adding ?hsCacheBuster=1234 (with any random number) to your URL, you’re essentially nudging HubSpot to skip the cache and give you the most up‑to‑date version of your page.
Normally, though, typing that in by hand every time is a chore. Who has time for that, right?
Well, I've got a super simple, one‑click solution for you: The HubSpot CacheBuster Bookmarklet!
It's a tiny piece of JavaScript magic that lives in your browser's bookmarks bar. When you click it on any HubSpot page, it does two things:
?hsCacheBuster=1234).Because the URL is technically "new" each time, your browser has to go fetch the latest version from HubSpot, completely bypassing any old cached content. No more staring at outdated pages!
It's incredibly easy to install. Just drag the button below directly into your browser's bookmarks bar. That's it!
Drag below button to your bookmarks bar:
Whenever you're on a HubSpot page and suspect you're seeing a cached version, just click your new "Clear HubSpot Cache" bookmarklet. The page will instantly reload with the freshest content.
Give it a try and let me know what you think! It's been a huge time-saver for me, and I hope it helps you too.
Important Note for Blog: While this CacheBuster works great for most HubSpot pages, there's a small exception for blog Topic (/topic/) and Author (/author/) pages. You might find that updates take a bit longer to propagate, even after using the bookmarklet. Just something to keep in mind if you're not seeing instant changes there!
