## Meaning

Built-in debugging and development tools included in web browsers and IDEs that allow developers to inspect, test, and troubleshoot code in real time.

Devtools is short for developer tools and refers to a set of integrated features that help programmers write, test, and debug code more efficiently. In web development, browser devtools like Chrome DevTools, Firefox Developer Tools, and Safari Web Inspector are essential for inspecting HTML elements, viewing CSS styles, monitoring network requests, and running JavaScript in the console. In software development more broadly, IDEs and text editors also include their own devtools for profiling, debugging, and analyzing application performance. Understanding how to use devtools effectively is a critical skill for modern developers, as it saves time during the development cycle and helps identify issues that would otherwise be difficult to find.

## When you hear it

The frontend team used devtools to identify why the API call was failing on production.

## Examples

- **in a standup:** "I spent an hour in devtools yesterday debugging the layout issue on mobile devices."
- **in a code review:** "You can verify this behavior by opening devtools and checking the Network tab to see the request payload."
- **in a team meeting:** "New developers should get familiar with devtools early because it's essential for frontend development."

## What native speakers say

- "Open devtools to inspect the element"
- "I found the bug using Chrome DevTools"
- "DevTools shows the network waterfall"

## Common mistakes

- ✗ "I need to devtools this bug." → ✓ "I need to use devtools to debug this issue." (Devtools is a noun, not a verb. You cannot devtools something; you use devtools to debug.)
- ✗ "DevTools are only for JavaScript." → ✓ "DevTools include HTML, CSS, JavaScript inspection, and network monitoring tools." (Devtools has many features beyond JavaScript, including DOM inspection, CSS debugging, and performance profiling.)
- ✗ "We devtools the application." → ✓ "We open devtools to troubleshoot the application." (Devtools is not used as a transitive verb; use phrases like open, access, or launch devtools.)

## Be careful

Devtools is a noun referring to tools, not a verb. Do not use it as a verb meaning to debug or develop.
