Overview
Product summary
Review the store description, core capabilities, and common use cases.
Pesticide for Chrome - Simple is a minimal Chrome extension for frontend developers.
With one click, it outlines every element on the page, helping you see how elements are structured, spaced, and nested.
This tool is designed to make layout debugging faster and easier by showing the visual boundaries of all elements, just like browser devtools, but more direct and distraction-free.
No setup, no configuration. Just click to toggle outlines on or off.
Whether you're inspecting box models, fixing margins and paddings, or simply understanding page structure, this extension saves time during development.
