element-source traces DOM nodes to code

This is one of those small utilities that can quietly reshape debugging workflows: instead of poking around DevTools manually, you can ask the page where a UI piece came from and land on the exact source.

• –It turns the browser into a code-aware surface, which is a big win for AI agents that need precise context before editing
• –The multi-framework support matters more than it sounds; source tracing is most useful when it works across the whole frontend stack, not just one ecosystem
• –The project’s real value is in compressing the UI-to-code loop, which should save time on brittle DOM sleuthing and handoff friction
• –The React Grab connection suggests a broader agent workflow, not just a debugging helper
• –Because it exposes file path, line, component name, and stack, it’s useful both for humans and for automation that needs structured source metadata
