LWC vs LWC OPEN SOURCE (OOS)

LWC (Lightning Web Components) and LWC OSS (Open Source) are both versions of the Lightning Web Component framework used for building client-side applications and UI components in the Salesforce platform. 

However, there are some differences between the two:

1. LWC is the standard version of the Lightning Web Component framework provided by Salesforce and is used within their ecosystem. 

LWC OSS, on the other hand, is an open-source version of the framework that can be used outside of the Salesforce environment.

2. LWC provides features and integrations with other Salesforce technologies, such as the Lightning Design System and Salesforce Apex, 

which are not available in LWC OSS.

3. LWC provides a higher level of security than LWC OSS, as it is built to comply with Salesforce's security standards and undergoes regular security assessments.

4. LWC OSS has fewer limitations in terms of customizations and can be used with any web stack or tooling.

while LWC is more tightly integrated with the Salesforce ecosystem and requires certain configurations to work with other Salesforce technologies.

In summary, LWC and LWC OSS are both versions of the Lightning Web Component framework.

But LWC is mainly used within the Salesforce ecosystem and provides more integrations with Salesforce technologies.

While LWC OSS is more flexible and can be used outside of the Salesforce environment.
