Methodology

About this ranking

SourceOpenRouter public app attributionUpdated Jul 29, 2026, 3:53 AM UTC

What is ranked

Popular orders reviewed harnesses by token volume in the selected window. Trending follows absolute excess token growth. Duplicate app identities are consolidated before ranking.

What is included

Public app attribution is filtered through a source-backed Harness identity review. Non-harness apps, wrappers, and gateways are excluded.

How to interpret it

Tokenizers differ across providers. Usage rank does not measure capability, quality, reliability, or total market share. Capability labels come from a separate first-party product review and do not affect rank.
