Our take

Reddit, HN, Polymarket, and GitHub work without configuration, while sources like X, YouTube, and TikTok need a setup wizard and your own keys or browser sessions. It is actively maintained with many community contributors and runs on Claude Code, Codex, Cursor, Gemini CLI, and other Agent Skills hosts. Results are ranked by engagement signals such as upvotes, likes, and market odds rather than by search engine ranking.
