Replyke

Replyke makes it easy to add social features to any app. It's what I kept rebuilding across my own projects, so I turned it into a general solution. I've been working on it for close to a year now, and have recently made the decision to go open-source.

It includes:

• A complete comment system (threaded replies, mentions, votes, moderation)
• A feed aggregation system with filtering, sorting, time-based queries
• In-app notifications for events like mentions, replies, follows, votes
• Support for user-curated lists and collections
• Follow relationships (users can follow others)
• Built-in authentication, or the ability to use your own user system
• A dashboard for content moderation, and user management (hosted version).

Everything is built around a consistent API. You can use it directly, or through the SDKs:

• React and React Native (CLI + Expo)
• Node.js and vanilla JS (server and client) - added soon

There are also prebuilt components if you want to drop in functionality fast, like a full comment section.

It's open source (Apache 2.0) and available here: https://github.com/replyke/monorepo

There’s also a hosted version if you prefer managed infra, but all the core functionality is open.

I've also built a few of projects with it that are also open source, like a features roadmap (to share pans with your users), complete forum (to foster communities), discord bot (makes content from your server public for SEO), a complete social network and more.
