Sublay

Add user accounts, content, and community features through one backend

Meet Sublay

Sublay provides backend infrastructure for applications built around users and their interactions. Projects start with sign-in and profiles, then add bundles for content, comments, reactions, files, spaces, messaging, notifications, and other common features. Developers keep control of their interface while using predefined services for the underlying data and behavior.

The platform includes permissions, moderation, reporting, and search capabilities, with SDKs for React, React Native, Expo, browser JavaScript, and Node, plus a REST API. Its SDKs are open source. Sublay is aimed at products such as marketplaces, team tools, learning platforms, or communities that need a connected user system without building each supporting service independently.
