Piecon is a tiny JavaScript library that dynamically renders progress pie charts directly in a page's favicon, with retina support. It falls back to updating the document title with the percentage in browsers that don't support canvas favicons.

Use cases

• show upload or download progress in the favicon
• display background task progress without a visible widget
• indicate page loading percentage in the browser tab
• render a dynamic pie chart icon in the favicon
• show progress in the tab title as a fallback for unsupported browsers

When to choose

• you want a lightweight, dependency-free way to show progress in the browser tab
• your app performs long-running background work and users switch tabs
• you need retina-crisp favicon graphics

When to avoid

• you need full-featured charting or dashboards
• you must support browsers without canvas favicon support with graphical output
• you need an actively developed library with recent commits and a repository license file
