I am experiencing slow website loading even when accessing webflow.com itself! , thought the problem was with my CMS site but it is related to webflow! I tested through GT Metrix and webflow.com and got a C and a bad performance and speed!

This Problem is super frustrating and seeing nobody talking about it!

The Problem Appears and Disappears so sometimes the website loads fast and sometimes super slow!

webflow.com is bloated and not well optimized IMHO and the impact of many many scripts is significant.

Hi, @A_E

Super slow loading is most often caused by large images, heavy animations, and unnecessary scripts. Optimizing media, simplifying interactions, and limiting third-party tools typically resolves the issue quickly.

  1. Optimize Heavy Images & Hero Content

Large or unoptimized images delay Largest Contentful Paint (LCP) and increase Speed Index.

Recommended actions:

  • Export images at correct display size (Figma/Canva).

  • Compress before upload.

  • Use WebP format.

2.Defer JavaScript (Reduce Blocking Time)

Scripts placed in the block rendering and increase Total Blocking Time (TBT).

Move custom scripts to Before tag and add defer:

3.Load Non-Critical CSS Asynchronously

Non-critical CSS (styles not visible on the first screen) should not block rendering.

Keep only essential above-the-fold styles as critical CSS.

4.Limit Third-Party Scripts & Embeds

Third-party tools (chat widgets, analytics, social feeds) often increase TBT and slow FCP.

  • Remove unused apps

  • Load only where needed (

5.Optimize Font Usage

Multiple fonts or many font weights increase render time and block text rendering

.Using font-display ensures text remains visible while fonts load.

Add this inside your custom CSS:

@font-face { font-family: 'CustomFont'; src: url('/fonts/customfont.woff2') format('woff2'); font-display: swap; }

Addressing these areas should lead to faster load times and a smoother experience across devices.

Alternatively , if you’d prefer not to improve performance issues manually, a third-party performance analysis tool like https://webflow.com/apps/detail/website-speedy can help identify heavy assets or scripts that may be affecting load and responsiveness.
