Buildermark

Buildermark, made by Gelatinous Development Studio, measures how much code in a project was generated by AI coding agents, automatically matching agent conversation logs with git commits to attribute every line of code, both local and open source, without requiring workflow changes or agent hooks. It offers agent attribution tracking showing the percentage of commits written by AI agents, conversation ratings through manual review or automated agent critique, and agent benchmarking to compare performance across Claude, Codex, Gemini, and Cursor. Buildermark provides native notifications displaying agent percentages at commit time, and is built as a local-first architecture with zero telemetry, supporting multiple agents including Claude Code, Codex, Gemini, and Cursor. A Team Server for organizational analytics is in development, currently accepting waitlist signups. Buildermark is open source under the MIT license, with free desktop and CLI apps, a maintained GitHub repository, and a working live demo.
