DeepSeek Usage Chart

A simple, self-contained HTML page that visualizes your monthly DeepSeek API usage and cost data. Everything runs locally in the browser — no data is ever uploaded anywhere.

How to use

1. Go to DeepSeek Platform → Usage Details → Export Records
2. Download the monthly usage ZIP file
3. Open index.html in your browser
4. Drag and drop the ZIP file onto the page (or click to select it)

Features

• Upload a ZIP — directly load the ZIP you downloaded from DeepSeek, no need to extract it first
• Key / model / date filters — toggle individual API keys and models, set date range
• Detail table — per-key per-model breakdown with summary-only mode, heatmap-style background gradients (column-wise normalization), and green-to-red subtotal text gradient
• Daily cost chart — stacked bar chart showing cost breakdown by model per day
• Cost distribution — sunburst chart of cost by model and API key; toggle to switch between sunburst, stacked bar, and normalized percentage view (with animated re-sort on legend click)
• Daily token trends — line chart tracking each token type over time; dual-axis mode prevents cache-hit from overwhelming the scale
• API Key token usage — grouped bar chart per API key; dual-axis support
• Light / dark theme — toggle in the header, respects system preference on first visit
• 100% local — all parsing and chart rendering happens in your browser; nothing is uploaded

Privacy

Your usage data never leaves your computer. The page has no analytics, no tracking, and no backend. You can verify this by inspecting the source or disconnecting your network after the page loads.
