WishKit

WishKit is a feature request board that lives inside your product. On Apple platforms (iOS, macOS, visionOS, watchOS, tvOS) it renders as native SwiftUI through an open-source Swift SDK. On websites and web apps it renders inline through a two-line web SDK. Users post ideas, vote on existing ones and comment, and the votes show you what to build next. You manage everything on a kanban board in the WishKit dashboard. Premium adds automatic emails to every voter when a request ships, in-app chat for iOS, replies to App Store reviews and capturing requests from X. Pricing is flat, with no per-user or per-seat fees, and there is a free plan.
