Relayfast is a software tool designed for small SaaS teams that frequently ship product updates. Its primary function is to manage the entire product update loop, from publishing changelogs to collecting feature requests and notifying users. The platform allows teams to write a single update and distribute it across multiple channels, including a hosted changelog, RSS feed, subscriber email, and an in-app widget. This centralized approach replaces the need for separate tools for each distribution channel. Key features include a rich editor for creating changelog posts with categories, media, and previews. Teams can send email updates only to verified subscribers, with clear unsubscribe options. The in-app widget can be embedded into the application, allowing active users to see launches where they already work. Widget targeting controls let administrators choose where the widget appears and which updates open by default. Feedback collection is integrated, turning reactions, votes, and feature requests into visible feedback attached to the same product history, rather than a scattered support queue. Typical use cases involve a workflow where a team drafts a release note once. When a feature requested by users is shipped, RelayFast helps close the loop by automatically publishing the update to the changelog, emailing subscribers, and showing an in-app announcement. This ensures users see what changed without relying on manual notifications. The tool is intended for teams that ship often and want every release to be visible to customers, with feedback remaining attached to the product’s history. Technical details include a hosted page for the changelog, RSS feed generation, email subscriber management, and a JavaScript widget for embedding into web applications. No specific programming language or framework requirements are mentioned, but the widget appears to integrate via a simple code snippet. The platform does not require users to maintain separate release notes or notification systems, as it consolidates these functions into a single loop.
