Changelog 2025.09

Playwright Test Support Beta

The Playwright testing feature is progressing nicely! This will enable the use of ordinary Playwright Test JS scripts for load testing and/or site monitoring, as an alternative or in addition to Browser Bots and Protocol Bots.

We look forward to a general release soon, but for now if you’d like to join the beta please contact help@loadster.com.

Improvements & Bug Fixes

• Added a section to the JSON exported test report with high-level metrics broken down by bot group.
• Fixed confusing date formatting on test reports with certain combinations of date preferences and timezones.
• Fixed a race condition that sometimes caused test reports to incorrectly show the test duration as 0:00:00.
• Improved multibyte character support in names of scripts, projects, etc.

Further Reading

Playwright Test support has been steadily progressing through experimental and early access phases, and this beta milestone brought it closer to general availability.

The JSON export improvements are particularly useful if you’re integrating Loadster into your CI/CD pipeline. With the Loadster CLI, you can trigger load tests from your build process and then parse the exported JSON report programmatically to check for regressions or threshold violations. Having bot group metrics in the export makes it easier to write automated checks that are specific to different parts of your scenario.
