Executive summary

Positions below are each product's position on the overall monthly board when the UTC month closed — they are not category-relative. The group covered here spans Agents.

Why it matters

This report is a fixed, reproducible record of one month of promotional activity on Harpd Rank. Unlike the live board, every number here is frozen at UTC month-end and tied to a named, immutable dataset, so researchers can cite a precise market snapshot rather than a moving target. Because Rank Points track maker promotional spend, the report is best read as a map of market attention for the period, not as a verdict on product quality.

Why the ranking looks this way

The monthly board orders products by Rank Points: one completed Harpd Credit spend creates one permanent Rank Point, so position tracks maker promotional activity during the month. Crew Tower closed at #10 with 0 Rank Points.

For context on what happened after the snapshot closed, today's live board shows Crew Tower now #62 on the live board — check the product profile for the full trajectory.

This is a market-attention signal, not a quality verdict: a lower position can simply mean the maker did not promote during the month.

Methodology

Data source: the closed September 2026 monthly archive snapshot of Harpd Rank (https://api.harpd.com/api/rank/archive/monthly/2026-09), immutable once the UTC month closed.
Scope: products whose board category is one of agents.
Position: the product's position on the overall monthly board in the snapshot (not category-relative).
Movement: per-product position delta against the August 2026 closed snapshot; new entrants are products absent from the previous snapshot.
Rank Points: 1 completed Credit spend = 1 permanent Rank Point. Paid placement, openly disclosed.

Limitations

Rank Points measure promotional activity on Harpd Rank, not product quality, usage or revenue.
The snapshot covers the monthly board's top 100 positions; lower positions are not archived.
Categories are self-reported by makers, so a product may sit in an unexpected category.
The group is small in early months; percentages on small counts move violently — treat shares as directional.
Movement is only defined between adjacent monthly snapshots; gaps cannot be interpolated.
