How we calculate this: Based on your inputs, your team deals with ~26 test failures/month, consuming 52 hrs and $5k in engineering time. Replay eliminates ~85% of that investigation time by delivering root cause and a suggested fix directly on the PR.

Backed by data: On the Web Debug Bench (177 real bugs), Claude Code + Replay MCP scored 76% vs. 61% without — a 15-point lift from time-travel debugging alone. Teams using Replay report reducing reproducibility time from 1–2 hours per engineer per day to near zero.
