Prototype performance is slow.

I have a prototype that is not excessive in size. It is not performing well for me or my client. I’ve seen this is a problem elsewhere and seems to be a Figma issue for many others.

Hey ​@PixelMac, thanks for reaching out! 

Let’s try to narrow down what might be happening. First, a few quick questions:

  • Are you seeing any specific error messages?

  • Is this happening in the browser, the desktop app, or both?

  • Does it only affect this particular prototype, or are other prototypes also slow?

  • If possible, does the issue persist when switching networks (for example, testing on a mobile hotspot)?

A few troubleshooting steps that often help:

  • Clear browser cache, sometimes stored offline data can cause performance issues. 
  • Restart the app/browser, force-quit Figma (or your browser) completely and reopen it in a fresh window.

 

Here’s our general troubleshooting checklist as well: https://help.figma.com/hc/en-us/articles/360040523973-Troubleshooting-checklist

 

Let me know how it goes!

No error messages. Just lag. It’s happening in browser and app, for multiple users. I haven’t tried other prototypes.
