Changelog 2026.01

2026.01

Monaco Code Editor

We’ve upgraded the script editor to use the Monaco editor (the same editor that powers VS Code) for code blocks and Playwright scripts. This greatly improves the experience when writing JavaScript.

Alongside this, the autocomplete system has been overhauled to provide context-aware suggestions for Loadster’s scripting APIs including bot, http, crypto, and more, with inline documentation pulled from the scripting manual.

Playwright Dataset Variables

Playwright Test scripts can now access dataset variables through the @loadster/bot helper library. This means you can parameterize your Playwright scripts with real test data from your datasets, just like you’ve always been able to with Browser Bot and Protocol scripts.

import bot from '@loadster/bot';

const [username, password] = bot.getVariable('credentials');

You can also access bot metadata like bot.getIteration(), bot.getBotNumber(), and bot.getTime() for relative timing. It’s a small API with a lot of power behind it.

Live Feedback for Playwright & Code Blocks

Previously, when a Playwright script was executing you wouldn’t see any progress in the Timeline until the entire script finished. Now you’ll see a live tile with a spinner as soon as each Playwright Test case starts, and a screenshot as soon as it finishes. No more staring at a blank timeline wondering if anything is happening!

The same improvement applies to commands inside code blocks in Browser Bot scripts, so you get real-time feedback as each command executes.

Monitoring Summary Emails

Weekly monitoring summary emails now include much more detail about each monitor’s performance over the past week. It’s a great way to keep a pulse on your site’s health without having to log in.

Fuel Plans

Loadster’s pricing has been simplified around Fuel Plans, making it easier to find the right plan for your testing needs. A new Usage page gives you a clearer picture of your fuel consumption and usage history.
