Independent empirical benchmark across 207+ AI coding agents and developer tools, evaluating Speed, Autonomy, Data Privacy, and Cost Efficiency.
Three weeks into our sprint, finance flagged our corporate card: $40/seat for overlapping coding IDEs plus $1,140 in raw frontier API overages because every agent turn was rescanning our entire monorepo from scratch.
