Why Token Viewer

Most coding-agent users can see logs, but not a clear answer to:

• How many tokens did I use today/week/month?
• Which model is expensive?
• Is cache helping or just noise?

Token Viewer turns raw local logs into a clean dashboard with trend charts and per-model breakdowns.

Key Features

• Local-only: scans local JSON/JSONL logs, no server required
• Fast incremental refresh: remembers file offsets for quick updates
• Token analytics dashboard: requests, input/output tokens, totals, cost
• Cost estimation: based on LiteLLM pricing tables (supports tiered rates)
• Date grouping: Day / Week / Month / Year / All
• Model drill-down: click rows to expand per-model usage details
• Cross-platform desktop: Windows, macOS (Intel + Apple Silicon), Linux
