Help us make O2S the best framework for composable self-service solutions!
Just to make it more clear what Open Self Service is...
Think of it like a composable frontend for customer portals, just as headless / composable storefront for e-commerce.
Instead of integrating with e-commerce platforms (like commercetools, Adobe Commerce, or SAP Commerce Cloud), O2S is built for customer service portals - we focus on connecting CRMs, ERPs, PIMs as well as more standard headless services like CMSs or search engines.
We handle API integration through our node/Nest.js based API Harmonization Server, acting as a backend-for-frontend layer. This approach decouples the frontend from backend APIs, prevents vendor lock-in, and simplifies API orchestration.
On the frontend side, O2S provides a fast, CMS-managed, Next.js-based app with pre-built but fully customizable UI components, built on shadcn/ui.
All of this is open source.
If this sounds interesting - head to our Github. We’d love to get your feedback!
