May Sale, AI-Assisted Debugging, and much more

Hello!

Since our December update, our team has been heads-down turning your feedback into features. Below is a quick tour of some of the bigger new features in Wallaby, Quokka, and Console Ninja so far in 2025. There's a lot to cover, and much more to come during the rest of the year.

Has your license lapsed? Or do you simply want to renew early? Now is a great time to do so, during our May sale. This discount is only available until May 21st @ 00:00 UTC. Use the links below to take advantage of this offer:

If you already have a personal license, you can renew early via your Wallaby Account and you will receive the same discount (or better, depending on your license type).

Copilot Agent Tools + MCP Server

AI agents are only as smart as the context they're fed. Our Copilot Agent tools and MCP server pump Wallaby and Console Ninja's rich runtime data (e.g. values, errors, coverage maps, execution paths) straight into Copilot Chat, Cursor, Windsurf, RooCode and other AI Agents. The result? Agents that really understand your codebase and can fix or write tests that make sense first time.

Interactive Runtime Value Graphs

Interactive Runtime Value Graphs let you explore complex data structures visually, right in your editor. The graph layout adapts well to various data shapes, and you can interactively collapse or expand branches and nodes to focus on the parts that matter. This new feature is available in Wallaby, Quokka, and Console Ninja.

Value Peek for Wallaby and Quokka

Simply hover any variable; Wallaby and Quokka then rerun only the affected code to show the fresh value inline with no noise, and no context switching. Value Peek can be toggled on or off to fit with your workflow.

Quokka Snippets

Need a quick boilerplate for file operations, a date formatting skeleton, or your favorite “FizzBuzz” kata? Quokka's new Snippets feature lives in one tidy file and can be launched when you create a new Quokka file. Pick a snippet and you're coding with autolog already switched on.

Bun Runtime Support for Quokka

Quokka now supports running your code using Bun as its runtime, a fast and modern alternative to Node. If you already use Bun in one or more of your project.json scripts, Quokka will prompt you to use Bun to run your code. You may also configure Quokka to use Bun by default in your Quokka settings.

More Updates and What's Next

There are more features we've added since our last update which we've not covered above. Check out our What's New Updates (Wallaby, Quokka) for more details.

Over the next few months, we're continuing to work on:

  • Deeper AI-assisted workflows in Wallaby and Console Ninja, powering smarter fix-it suggestions and context-aware test generation.
  • Statistical Insights for Wallaby that help identify where and why your tests are failing.
  • Comment directives for Quokka, so you can start a run or tweak settings right inside your code.


As always, thank you for being a part of our community. If you have any feedback or suggestions, please don't hesitate to reach out.

Happy Coding! 🧑‍💻
