# Loadium Updates – A Completely Rebuilt Loadium

September 5, 2026

Loadium has been rebuilt from the ground up. Over the past year we redesigned the entire product and rewrote the interface on a new technology stack, while replacing every backend service behind it.

Every screen has been rebuilt, from login to the admin panel. Your tests, reports, files, and account settings have all been migrated, and every test type works as before.

### What's new:

* Completely new interface, designed and built from scratch.
* Reorganized navigation and sidebar for faster access to tests, reports, and settings.
* Consistent dark and light modes across every screen.
* Improved layouts on smaller displays.
* New Test Initialize screen showing progress while your test starts up.
* Search, rename, and favorite your tests from the Tests page.
* Sticky column headings when scrolling long test lists.
* Engine size selection is now a separate step, with a warning if you continue without a matching engine.

### Why We Rebuilt

The previous foundation had reached its limits. Rebuilding it gives you a faster and more consistent interface today, and lets us add capabilities that were not possible before. The first of those is multi-company accounts, covered in a separate release note.

Our documentation has been updated to match the new interface. If something does not work the way you expect, let us know.

### Improvements

* Added a pie chart to the Errors tab on the Responses page.
* Added search and dynamic filtering to the Errors by Label table.
* Individual metrics can now be shown or hidden in the Error Distribution chart.
* Time range filtering on the Responses page now updates response counts dynamically on the Success and All tabs.
* The All, Success, and Errors filter on Request Stats now applies to the charts below it.
* Time range filtering now behaves consistently across every report screen.
* Active filters stay visible as you move between report pages.
* Charts on the Compare screen can be expanded to full size.
* Labels on the Compare screen can now be searched and removed in bulk.

### Bug Fixes

* Fixed mismatched values between the chart and the table on the Compare screen.
* Fixed Received and Sent Byte metrics displaying in the wrong unit on the Timeline Report.
* Fixed incorrect data shown on the Error and Success tabs of Request Stats.
* Fixed sorting on the Request Stats page while a time range filter is active.
* Fixed a mismatch between the overall average response time and the value shown on the chart.
* Fixed unreadable chart tooltips in dark mode.
* Fixed an issue where test runtime was displayed incorrectly.
* Fixed an error when loading a test with no data into Compare.
* Aligned Locust reports on the Responses page with JMeter reports.
* Fixed an issue where uploading a JMX file overrode the test name and existing test configuration.
* The missing CSV warning now persists through the Run Test step and points to the fix.
* Fixed the "JMeter Settings" heading appearing when Gatling is the selected test type.
* Fixed User Per Engine configuration not applying on the Test Edit screen.
* Fixed overflow at the bottom of the Test Helper panel.
* Fixed inconsistent time zones and layout on the Test Schedule tab.
