JSEval

Notice: Conclusion of the JSEval Experimental Plugin

Date: August 10, 2026

Subject: End of the JSEval experiment and next steps

We have officially concluded our JSEval experiment. We gained valuable insights into how developers interact with this tool. Based on our findings, there is no value in continuing JS Eval in its current form, given the evolving patterns of how developers engage with AI agents.

Consequently, the JSEval experimental plugin has been removed from the JetBrains Marketplace.

What’s next?

While the plugin is being retired, the underlying technology is not. We are actively researching how to reuse the technology behind JSEval to support agentic debugging turns, enabling more efficient, agentic debugging workflows directly inside WebStorm.

We value your feedback
