About
StackReplay analyzes a developer's local AI coding tool history (Claude Code, Codex, and similar tools) entirely in the browser, calculating what those recorded model calls would have cost at published API prices. It then replays the same event sequence against other subscription plans or APIs to show where an allowance or credit pool would have run out.
At a glance
StackReplay reads coding-agent history and charts token use, models and activity. It is worth opening if you want to understand what your tools spend time and tokens on across several sessions.
Good fit
Developers comparing usage across supported harnesses who can start with the public sample or an approved history export.
Consider something else when
Use your provider’s account dashboard when you need actual billed amounts or plan limits.
Start here
Open the fictional sample to understand the charts, then use a small approved export. Compare one model and date range against your own usage records.
Cost and requirements
The hosted browser app supports histories from tools including Claude Code and Codex. The project documents local parsing and optional sharing.
Limits to know
API list-price values estimate what requests would cost under another billing model. The project says raw logs stay local, while creating a share link sends the card’s derived figures.
