Test failures just got easier to understand.

We've refined when screenshots are captured (before or after actions, depending on their nature) and introduced visual bounding boxes that highlight exactly which element the runner interacted with.

What this means for you:

★ No more guessing what went wrong.

★ Bounding boxes, which are configurable in advanced settings, show you the runner's decision-making process, making debugging significantly clearer and faster.

We've rolled out new Browserless locations, fully owned and operated by Thunders.

This means complete control over infrastructure, scaling, and maintenance, delivering tangible improvements where they matter most.

What this means for you:

★ More stable test execution

★ Faster response times

★ Reduced costs through optimized infrastructure

We've simplified IP whitelisting by reducing the number of addresses per location, while keeping legacy locations active to ensure a smooth transition for teams with existing configurations.

Christmas comes early this year, and our gift to you is a feature you’ve been asking and waiting for.

Hot Reload is here to make you save time and money.

You can now resume execution exactly where the last successful step stopped, no reset, no wasted time:

• Accelerate test creation
• Save time and money by running only what’s necessary
• Debug efficiently by testing your fix immediately.

Hot Reload pushes Thunders toward a smarter, more scalable, and high-performance testing experience.

We replaced the previous multi-step onboarding wizard with a single continuous flow, making it faster and simpler to set up a new organization.

This provides you with a clear, central location to configure and manage all your organization’s preferences.

The “Steps to Actions” module, which converts test steps into browser-executable actions, has been significantly optimized.

• Tests now run up to 3× faster, reducing feedback loops.
• The success rate on our test set has increased from 68% to 79%, improving reliability
• Execution demonstrates greater stability and consistency, ensuring predictable automated test runs.

You can now view the source files and prompts used to generate each Test Plan. This provides full transparency into the test generation process, making it easier to understand, verify, and refine test plans.

We’ve updated the Bug Report system to align with the project’s language, ensuring consistency and clarity.

This was implemented to help clients receive and interpret reports in the language of their project, making collaboration smoother and reducing the risk of misunderstandings.
