Claudetop Reveals Claude Code Session Costs
Claudetop, an open-source status-line tool for Anthropic's Claude Code, provides real-time token and cost visibility per session, displaying model, duration, cache efficiency, burn rate and projected monthly spend. Released with install scripts and dynamic pricing updates, it supports model-cost comparisons (Opus, Sonnet, Haiku), smart alerts and session analytics, and was built after a hidden compaction error produced a $65 bill despite a $10 estimate; pricing reflects March 2026 rates.
Key Points
- 1Shows per-session token and dollar usage in real time, including model, duration, and cache metrics
- 2Highlights hidden costs from compaction and cache misses, demonstrated by $10 estimate vs $65 actual bill
- 3Enables practitioners to compare model costs, monitor burn rate, set budgets, and optimize cache usage
Scoring Rationale
Practical, actionable open-source tooling improves cost visibility; limited scope to Claude Code users and single-source project.
