Embed the Lag Check

Put a free Lag Check on your forum, blog or help page. Visitors get a score and a bufferbloat grade in about 30 seconds, and a link to the full result with fixes on The Net Fix.

Copy this snippet

<iframe src="https://thenetfix.com/embed/lag-check" title="Net Fix Lag Check" width="100%" height="300" style="max-width:480px;border:0" loading="lazy"></iframe>

It works from 320 px wide. A height of 300 px fits the result on a phone.

What the widget does

  • Runs the same speed and lag test as the Lag Check, against Cloudflare's network.
  • Loads no ads, analytics or tracking scripts, and The Net Fix sets no cookies on your visitors.
  • Stores nothing. The full result link carries the numbers in the link itself, never an IP address.

Who it's for

Game communities, Discord and forum moderators, help desks and anyone who writes guides about lag or Wi-Fi. When someone asks "why is my ping so bad?", they can run the test right on your page instead of being sent elsewhere first, and come back with a grade you can both read. A poor bufferbloat grade usually points to the router queue, which the bufferbloat guide fixes step by step.

Common questions

Is the Lag Check widget free to embed?

Yes. Copy the snippet and paste it into any page that allows an iframe, such as a forum post, blog, help centre or community guide. There is no sign-up and no key, and the widget runs the same test as the full Lag Check.

Does the widget track my visitors?

No. It loads no ads, analytics or tracking scripts, and The Net Fix sets no cookies on your visitors. It stores nothing: the full result link carries the numbers in the link itself, never an IP address.

What size should the embed be?

It works from 320 px wide, and a height of 300 px fits the result on a phone. The snippet sets a full width with a 480 px maximum, which suits most forum and blog columns without any extra styling.

What do my visitors see when the test finishes?

A score and a bufferbloat grade, which shows how much lag rises while the line is busy. A link opens the full result on The Net Fix, with the fixes that match what the test found, such as Smart Queue settings or a Wi-Fi change.
