Optimize Mobile & Web Network Performance
Large API payloads directly slow down mobile application render times and consume user bandwidth. While it's easy to see the aggregate size of a response via Chrome DevTools, it's incredibly difficult to figure out exactly what is taking up the most space.
How It Works
📊 Array Aggregation
If your root JSON is an array of records, the analyzer parses all records and aggregates the size of identical properties, showing cumulative cost of each column.
🔍 Object Analysis
If your root JSON is an object, it measures the exact byte size of every top-level key and builds an intuitive Pie Chart and Data Table.
🔒 Client-Side Processing
Measurements are done strictly on your device using native Blob byte-size extraction for high precision. Your data never leaves the browser.
