Add an SPFX webpart without being a tenant admin?

[barlage]

I am an admin of a SharePoint communication site and I'm wondering if there is any way for me to add/create an SPFX webpart without having tenant admin permissions? Please share a tutorial if this is possible. Thanks!

Yes, it is possible using the SharePoint "site collection" level app catalog. Try this:

1. Ask your tenant administrator to create a site (site collection) and grant you "Site Collection Administrator (SCA)" permissions
2. Ask your tenant administrator to enable site collection level app catalog by following this article: Use the SharePoint site collection app catalog 
3. Then you can develop the SPFx solutions on your computer & deploy the solutions on site collection app catalog for adding and testing web parts.

Check these documentation for SPFx and development environment setup:

1. Overview of the SharePoint Framework 
2. Set up your SharePoint Framework development environment 
3. Build your first SharePoint client-side web part
