Reddit

Community-driven discussion platform where users post links, share content, and converse in topic-based subreddits. Threaded comments, voting, and moderation tools shape how communities self-organize and surface content.

Reddit hosts thousands of communities and offers a public REST API plus a developer platform for building on top of the site. The API supports OAuth2, listing endpoints with cursor-based pagination, and fullname identifiers for posts, comments, subreddits, and accounts. Devvit, Reddit's developer platform, lets you build interactive games and moderation apps that run inside Reddit, with free hosting and distribution to millions of users.

Key capabilities:

• REST API with OAuth2 for programmatic access to posts, comments, subreddits, and user data
• Devvit platform for building games and mod tools that run natively on Reddit
• Cursor-based listings with fullname pagination, modhashes for CSRF protection
• Subreddit structure for community segmentation and topic-based content
• Data API for approved use cases such as automated moderation and research

Developers integrate Reddit for community engagement, content syndication, and sentiment analysis. Moderation teams use the API and Devvit to automate rules, queue management, and custom workflows. Researchers and data teams pull public discussion data for analysis, while game and app builders deploy experiences directly inside Reddit communities.
