MeterMyData puts a meter on repeated data
A free, local tool that measures repeated data in HAR files, live traffic, or saved files.
- For
- Developers auditing repeated API and data transfers
- Worth noticing
- The live forwarder binds to 127.0.0.1; token-billed APIs show percentages only, not dollar estimates.
Field notes
The page offers three measurement paths: a HAR-file meter that hashes inside the browser, a localhost forwarder for live traffic, and an offline folder mode for saved responses, exports, or logs with complete bodies. Its reporting separates repeated bytes from billable repeats and any potentially addressable spend, which appears only after the user confirms provider billing and rates; token-billed APIs get percentages only. The listed percentages are from the project's own test traffic, and the page notes that chunk size changes results.
