You may want to disable Speed Insights in your project if you find you no longer need it. You can disable Speed Insights from within the project settings in the Vercel dashboard. If you are unsure if a project has Speed Insights enabled, see Identifying if Speed Insights is enabled.
If no data has been collected yet then you will see an Awaiting Data popup. From here you can click the Disable Speed Insights button:
If data points have been collected, click on the ellipsis on the top-right of the Speed Insights page and select Disable Speed Insights:
When you disable Speed Insights in the middle of your billing cycle, it will not be removed instantly. Instead it will stop collecting new data points but will continue to show already collected data until the end of the cycle, see the prorating docs for more information.
If you have many projects on your Vercel account and are not sure which of them has Speed Insights enabled, you can see this from the dashboard without needing to check each project separately. The different circles in the right corner of each project card will show the Speed Insights status.
If the project uses a supported framework but Speed Insights is not enabled, then the circle will look like the below:
If Speed Insights is enabled but no data points have been collected yet then it will show an empty circle, like the below:
If Speed Insights is enabled and data points have been collected then the circle will be coloured with a number inside, similar to the below image:
