Downgrading your Webflow plan should not affect the custom code you have added to your site. The added code will remain intact, and the features implemented using the code should still be accessible.
When you add custom code to your Webflow site, it becomes part of the site's design and functionality. It is not directly tied to your Webflow plan. So, even if you downgrade your plan, the custom code will still be present and functional on your site.
However, it's important to note that certain features and functionality may be limited by the plan you are on. For example, some advanced interactions or CMS functionality may be exclusive to higher plans and will not be accessible if you downgrade.
If you have implemented specific features using the code that are dependent on features of a higher plan, those features may not be functional if you downgrade to a plan that does not include them. For example, if you used custom code to implement dynamic filtering and downgraded to a plan that does not include dynamic filtering functionality, that specific feature may not work as expected.
In summary, downgrading your Webflow plan should not affect the custom code you have added to your site, but certain features and functionality may be limited depending on the plan you are on. It's important to review the plan features and limitations before making any changes to ensure that the desired functionality will continue to work as expected.
