What these numbers measure
Data scope: these rankings use a public app-ranking dataset ingested by our daily pipeline; the continuously refreshed view lives at the live agent harness rankings. Token and request totals count only traffic captured by that dataset. They do not represent each product's total usage, since many agents route most traffic through first-party keys, and rank changes apply only within this routed-traffic dataset. Snapshot: August 31, 2026; latest complete windows end August 30.
Disclosure: Hermes Agent is a harness we operate. HarnessRouter itself is not ranked here; it is the layer above this catalog, not a competitor within it.

Method
How this ranking is calculated
- Data source: the public routed-usage dataset behind our live agent harness rankings, ingested by our pipeline daily.
- Primary metric: routed tokens per app in the stated window.
- Primary period: the latest complete rolling 30-day window; momentum uses the latest complete seven-day window.
- Rank changes compare the latest window to the preceding same-length window, with exact dates stated on each table.
- The live, continuously updated version of this data is the agent harness rankings page; this report is its dated monthly record.
Run them
From reading rankings to running harnesses
Popularity is one signal; fit for your task is the decision. HarnessRouter is the world's first unified interface for agent harnesses. That means one API contract for tasks, sessions, streaming, files, and results across vendors' complete harnesses. Several of this month's top ten, including Claude Code, Cline, Hermes Agent, and DeepSeek Harness, run through it today, eight harnesses in all with the list growing, so the ranking above can become a same-task comparison on your own workload.
FAQ
Agent harness rankings FAQ
What are agent harness rankings?
A ranking of agent harnesses by token volume observed in a public routed-usage dataset during a stated window, as ingested daily by our pipeline. They measure usage within that dataset, not each product's total worldwide usage.
How are the rankings measured?
The main table orders harnesses by observed routed tokens in the latest complete 30-day window, with rank changes against the preceding 30-day window; a seven-day table shows momentum. Exact dates are stated on every table.
Why is Hermes Agent ranked number one?
Hermes Agent recorded the highest routed-token total in the latest 30-day window, 48.10T. That establishes #1 within this dataset, not across all providers or first-party traffic. Disclosure: Hermes is a harness we operate, ranked by the same data and method as every other entry.
Where is the live version of this data?
On the agent harness rankings page, which updates daily. This report is the dated monthly record of it, published so August's movements stay citable after the live page moves on.
Will this report be monthly?
Yes. Each edition freezes the latest complete snapshot at month end, publishes the 30-day and seven-day tables with their comparison windows, and records the movements. The September 2026 edition follows in early October.
Popularity is a signal. Your task is the judge.
Run the ranked harnesses through one API and keep the choice measurable month after month.
