Review code alerts

Last updated: March 20, 2026

Available with any of the following subscriptions, except where noted:

HubSpot's code alerts dashboard gives you a centralized view of technical issues detected across your HubSpot website — including pages, blog posts, templates, and stylesheets. Instead of discovering problems one page at a time, you can see everything in one place and take action quickly or send more information to your development or IT team.

If you're a developer, learn more about debugging HubSpot CMS code.

This dashboard can be useful for:

  • Reviewing the overall health of your website's content and code.

  • Identifying pages that may be loading slowly or not rendering correctly.

  • Flagging issues to your web team or developer for follow-up.

Below, learn more about code alerts.

Please note: code alerts are related to technical issues in your website's code and structure. They don't flag content quality issues like broken links, outdated copy, or SEO problems. For more information about troubleshooting those, check out HubSpot's SEO recommendations tool.

Access code alerts

If you're logged in to your HubSpot account, you can access the code alerts tool from any of your published pages:

  • On a published page, click the HubSpot sprocket icon in the top-right of the page.

  • Select View Code Alerts.

Alternatively, you can navigate to it directly using this link.

Reviewing alerts

For each issue detected across your site, the dashboard will display the name of the asset and its type, the type of issue, a description of the issue, and the date of when the asset was last checked. A row will be included for each individual issue, so a page with several issues would appear multiple times in the list.

To take action on an error or view more details, you hover over the row, then click Actions. Depending on the asset type and error, you can select from options including:

  • Open in design manager: open the asset in the design manager.

  • Open debug info: open the affected page with ?hsDebug=true, which will provide more information about the error.
  • Show syntax error: open a dialog box containing more information about syntax errors.

Asset types and errors

The tables below provide an overview of the types of assets and errors that you can find on the code alerts dashboard.
