# Lightning Web Components (LWC) support
The Salesforce Platform now allows developers to build Lightning components using [Salesforce Lightning Web Components (LWC)](https://developer.salesforce.com/docs/component-library/documentation/en/lwc/lwc.get_started_introduction).

However, due to security and technical constraints, a custom Lightning web component can't access a Lightning web component or module in a custom [namespace](https://developer.salesforce.com/docs/component-library/documentation/en/lwc/lwc.create_components_namespace).
In addition, the Salesforce platform doesn't support the integration of [third-party Web components](https://developer.salesforce.com/docs/component-library/documentation/en/lwc/security_locker_custom_elements).

Although we look forward to creating more LWC and phasing out our older Aura components in the Coveo for Salesforce package, at this time, we will continue to enhance and support our existing [Coveo Lightning Aura components](https://docs.coveo.com/en/1209/) that leverage the Salesforce Lightning [Aura component](https://developer.salesforce.com/docs/atlas.en-us.lightning.meta/lightning/intro_components.htm) framework.

Since many of our customers wrap our components into [custom Lightning components](https://docs.coveo.com/en/1193/) to enable flexibility for customizations, like [adding custom context](https://docs.coveo.com/en/3290#adding-context-with-custom-code), creating new components as LWC isn't an option because the cross-namespace limitation would block them from wrapping the new Coveo for Salesforce components.
Once Salesforce addresses these limitations, we will re-evaluate our plans for LWC development in the Coveo for Salesforce package.

As an alternative, we've introduced the [Coveo Quantic](https://docs.coveo.com/en/quantic/latest/) package.
It's released as an [unlocked package](https://developer.salesforce.com/docs/atlas.en-us.sfdx_dev.meta/sfdx_dev/sfdx_dev_unlocked_pkg_install_pkg.htm).
As such, it's not subject to cross-namespace limitations.
It's a library for assembling powerful and responsive Coveo for Salesforce search interfaces.
Its components are self-encapsulated, composable, and lightweight.
