SingularityHQ continuously classifies discussion about AI coding tools across Reddit's developer communities — r/ClaudeAI, r/ChatGPTCoding, r/cursor and more. Every post and comment that mentions a tool like Claude Code, Cursor, GitHub Copilot or Windsurf is scored on a six-point sentiment scale, then aggregated into the leaderboard above. Unlike synthetic coding benchmarks, this measures perception: what working developers say when they're not being marketed to. The historical trend view shows how each tool's reputation moves after a launch, price change or outage.
