Blume Sidecar provides a narrow desktop companion that monitors coding agents for software development teams and individual developers. The platform tracks every agent's activity across different harnesses, surfaces real-time progress, and identifies when chat interactions contradict established codebase rules. Blume helps teams build agentic-native codebases by maintaining consistent context, reducing coding errors, and minimizing workflow disruptions. The tool integrates with popular coding agents like Cursor, Claude Code, and Codex to provide comprehensive oversight.
