DIVE vs Chrome DevTools

DevTools is a debugger. DIVE is a design surface that emits structured diffs and ships them to AI agents.

Chrome DevTools is the universal default, free, built-in, every web developer knows it. DIVE is what you reach for when DevTools' lack of persistence, lack of visual controls, and lack of agent handoff start to bite.

Pick DIVE when

You want edits that persist across reloads and sessions.
You want real visual controls (sliders, colour pickers, motion, effects) instead of typed CSS strings.
You want to ship the diff to an AI agent or to engineering as a structured spec.
You're a designer or QA without a strong CSS background.

Pick Chrome DevTools when

You're debugging behaviour, not visuals.
You need DevTools' Network / Performance / Application panels.

The honest take
