Replyke

Replyke is an embeddable community infrastructure platform that enables product teams to add rich social features directly inside their applications. It provides the building blocks for modern in-app communities, including comments, reactions, voting, activity feeds, and notifications, without requiring teams to build and maintain these systems from scratch. The primary goal of Replyke is to help SaaS products, marketplaces, and platforms increase engagement and retention by making user interaction a native part of the product experience.

Replyke offers a modular set of components that can be integrated selectively, such as threaded comments, upvotes/downvotes, mentions, and user-to-user interactions. It supports real-time updates so that feeds, comment threads, and notification panels stay in sync across devices and sessions. The platform typically exposes a clean API and prebuilt UI elements, allowing developers to customize styling, permissions, and behavior to match their existing product. Replyke also centralizes community data, making it easier to track activity, moderate content, and enforce rules at scale.
