I just tried using LWC on my local, but not able to use <lightning-input />. Is it available for open source? Is there any way to bring prebuilt lightning web components with lightning namespace to local?

Currently no - none of the platform base component are available for off platform usage. Salesforce is targeting to open Source them in late July (#safeharbor) but their api / shape may also be slightly different than the known one due to missing Salesforce Service - will we see

For the 2nd Question - the only way as of today to use existing base components outside the platform would be via Lightning Out which is a different approach. I would wait those couple of months to see how its evolve with the LWC Framework

  • Or you can just write them by yourself, some of them are pretty easy to reproduce/reverse engineer (like lightning-input, button etc) Jun 16, 2019 at 11:26

Yes, in a way they are available, checkout this npm to use base lightning component in your OSS LWC. Base Lightning Components
