New AI-Powered Custom Metrics

Release Date: June 16th 2025

To help you quickly and easily create metrics and collect bespoke data about your site, we’ve created a new way of creating custom metrics.

Previously, this was only possible via Custom Extractions (which would require knowledge of RegEx), or had to be set up by our team. Now, however, you can easily set up these custom metrics, assisted by AI to create the code based on your specification. As with Custom Extractions, you can create up to 25 custom metrics per project, and you’ll find the option for this in step 4 of the project setup.

Accessibility Legacy Report Removal

Release Date: June 10th 2025

While adding total instances to the accessibility errors report, we identified a couple of legacy reports that were no longer required following updates to Level A Parsing and Time and Media. We have now deprecated these reports, which may slightly affect the overall Level A health score, and those for Parsing and Time and Media categories.

Screenshot and Lighthouse Viewer

Release Date: June 5th 2025

We’ve added a setting for site speed projects that allows you to view the Lighthouse screenshot and an embedded version of the Lighthouse Viewer within Lumar.

The new setting is available in Step 1 of the crawl setup, and also in the advanced settings in Step 4, in the Report Setup section.

Please note that enabling this feature will use an additional 1 credit per URL crawled. We therefore encourage you to use this feature on smaller crawls, rather than a full site crawl.

Once enabled, you can view the Lighthouse Viewer and Screenshot for a URL in the Page Details View. From a Lumar report, click on an Example URL to access the Page Details View. You can then choose Lighthouse Viewer from the left-hand navigation.

New Crawl Archiving Policy

Release Date: June 3rd 2025

To maintain the performance of our platform as the number of customers and crawls grows, we’ve made some changes to our crawl archive policy.

As before, all crawls will be automatically archived after 60 days. In addition, we will now retain the latest 7 crawls in a project and automatically archive any older crawls, even if they were run within 60 days. This means the change will only impact hourly and daily crawls.

For example, if you are running a daily crawl, you will have a week’s worth of crawls in your project after 7 days. When the next crawl runs on day 8, the oldest crawl will be automatically archived, and this process will continue on each subsequent day.

Trend data from these crawls will still be available to view in Lumar reports and dashboards. You can also unarchive any crawl to access the details whenever you need. Unarchived crawls will be automatically archived again after 7 days.

If you have any concerns with the new policy, please get in touch with our support team at support@lumar.io.
