Changelog 2026.04

Page Performance Scoring

Loadster’s Browser Bots and Playwright Bots now calculate a single page performance score from Core Web Vitals and other page timing metrics, and surface it in a few different places:

• In the Page Timings tab when you run a script in the editor, alongside the individual metrics.
• In monitoring, where the score is tracked over time and can be used with thresholds and trending, just like any other metric.
• In the free website speed test, so you can get an instant page performance score for any URL.

This score is similar to a Lighthouse score (calculated in almost the same way) and makes it easier to spot regressions and track performance improvements over time, without having to interpret each individual metric on its own.

Two-Factor Authentication (TOTP)

You can now turn on TOTP-based two-factor authentication (2FA) for your Loadster account. It’s optional and works with any standard authenticator app (Google Authenticator, 1Password, Authy, and so on). This is handy if your team has security or compliance requirements around account access, or if you just want your account to be more secure beyond the normal security best practices like choosing a secure and unique password.

Set Variables From Browser Script Code Blocks

Browser scripts can now set page variables from inside a code block, making it easy to pull values from a dataset (or compute them on the fly) and use them in Evaluate Blocks.

The following takes a value from a bot’s dataset variable and sets it as a value on the page currently loaded in the browser.

browser.setVariable("apiToken", bot.getVariable("API_TOKEN"));

Variables set this way become available to on-page JavaScript running in an Evaluate Block or in on-page JavaScript executed with browser.eval(...).

Playwright Recording & Test Generator Improvements

The Loadster Recorder browser extension now supports recording Playwright scripts! This is in addition to the Browser Bot and Protocol Bot scripts it previously supported.

Protocol Bot TTFB by URL

Protocol Bots now report Time to First Byte (TTFB) per URL in the test report, alongside the other response time metrics. The “Average TTFB by URL” view has been fixed up too, so you can see exactly which URLs are slow to start responding under load.

Protocol Script Inspectors

The tooltip inspectors in the protocol script editor have a cleaner layout and a couple of small bug fixes, making it easier to inspect requests and responses while editing a script.

Other Improvements & Bug Fixes

• Made traces more resilient when the page is no longer available, so you’ll get a useful trace and screenshot even when something has gone wrong on the page.
• Added clearer messaging around “Upgrade Required” for cloud regions in trial accounts, as well as password length requirements.
• Adjusted the maximum project limit and made it no longer count deleted projects.
• Fixed a few loading indicators that were stuck on or weren’t appearing when they should.
