https://github.com/pt-nakul-sharma/linkio-rails

LinkIO is a self-hosted deep linking solution for mobile applications, an open source alternative to Branch.io. It generates Apple App Site Association and Android assetlinks.json files, performs smart app-or-store redirects, supports fingerprint-based deferred deep linking, and tracks referrals. It ships a framework-agnostic core, a mountable Rails engine, and Rack middleware.
