Infra for User-Powered Products

Sublay provides backend infrastructure designed for user-powered products, addressing recurring engineering challenges such as content modeling, threaded discussions, permission management, ranking pipelines, search indexing, notification systems, social graphs, and moderation queues. It offers a modular approach through pre-modeled bundles, allowing developers to select and deploy only the components needed for their application. These bundles include features such as hierarchical comments with nested replies and moderation, reactions and votes with multiple reaction types, nested spaces and communities with roles and membership approvals, notifications for over 14 event types, feeds with advanced filtering and personalized sorting, real-time 1:1 and group chat, follows and connections supporting both one-way and mutual relationships, AI-powered vector search with an integrated answer endpoint, and event management with RSVP tracking and visibility controls.

Each bundle integrates directly with Sublay's core content model, where every piece of content—such as posts, articles, products, videos, or listings—is treated as an entity. Developers can define new entities from scratch or map existing records using foreign IDs, enabling seamless integration without requiring data migrations or schema changes. The platform's infrastructure layer includes a relational Postgres database with support for custom tables and columns, hosted file storage with CDN delivery and automatic resizing, built-in authentication supporting email, OAuth, and JWT sessions (with the option to bring your own authentication), and beta support for push notifications via APNs, FCM, and Web Push.

Sublay is built for developers aiming to accelerate the development of interactive applications such as learning platforms, marketplaces, or SaaS tools, allowing them to focus on their core product rather than foundational infrastructure. It provides SDKs for multiple platforms, including TypeScript, React, React Native, Node.js, and JavaScript, and is open source. The platform offers a free start option, making it accessible for projects at various stages.
