Developer Experience

What makes LWC Lens different

Purpose-built for the way Salesforce developers actually debug. No configuration, no connected app, no permission set to deploy.

Hover to identify

Move your cursor over any element on a Lightning page and LWC Lens instantly highlights the component it belongs to. No clicks, no toggles.

Full component tree

Navigate the entire hierarchy of the current page. See exactly which parent wraps which child, with one-click jumps between nodes.

Copy component paths

One click copies the component selector to your clipboard. Paste it straight into a bug ticket, a Slack thread, or your next debugging session.

Built for everyday debugging

Lightweight, keyboard-friendly, and out of the way when you do not need it.

Standard + custom LWCs

Detects both Salesforce-shipped base components and your own c-namespaced LWCs on the same page. Works on managed packages too.

Zero setup

Install from the Chrome Web Store, open any Salesforce page, and it just works. No org-side install, no admin approval.

Sandbox and production

Works on any org type — developer sandbox, UAT, staging, production. No URL whitelisting required.

Free forever

No subscription, no feature gate, no upsell. One of the many tools the Tucario team uses daily, now shared with the community.

Why it exists

Every Salesforce developer has had the same moment: you need to change the behaviour of a page section, but you cannot figure out which LWC owns that chunk of the DOM. You inspect the element, see a dozen nested c- components, and lose ten minutes tracing it manually. LWC Lens was built by Tucario engineers because that moment happened to us too many times. It surfaces the answer in the one place you already are — the browser — without asking you to install anything in Salesforce.
