Hi, 

Odoo looks awesome because of its modularity, ease of use and Python. Though I am wondering if I can start small with the one or other e-commerce project, even for smaller shops, so it should definitely not be the enterprise version.

Are there any other options than odoo online? As far as I understand the community edition does not support ecomerce or not all of its features.

From the technical side, I would like the frontend to be a PWA (Progressive Web App) with quite some freedom on customization, maybe I even need a complete custom front-end built from scratch. Does any odoo non-enterprise option support a REST API on the backend in this direction?

Thanks for any help.
