Every dataset Harpd publishes is free to quote, redistribute and build on — including commercially — under CC BY 4.0. Attribution is the only condition. Pick a dataset below and copy the line.
Quick answer
Can I cite Harpd data, and how?
Yes. All 8 Harpd datasets are published under CC BY 4.0 and can be quoted, redistributed and reused commercially as long as you attribute Harpd and link the licence. Each dataset below carries a ready-to-copy citation with the data date it refers to, the methodology behind the numbers, and the coverage the numbers apply to.

Cite a dataset
The as of date is the dataset's own data date — it moves when the data changes, never on a rebuild. A dataset with no date shown has no machine-readable timestamp yet, and we would rather show nothing than guess.
Harpd Historical Ranking Dataset
Immutable closed-period snapshots of Harpd Rank, used to derive movement, new entrants and category shifts in research reports.
Harpd Product Directory Dataset
Product entities in the Harpd dataset: name, slug, category, capabilities, verification state, profile URL.
Harpd Category Dataset
Harpd categories with product counts and board URLs.
Harpd Rank Open Data (non-sponsored signals)
Deliberately excludes Rank Points and ranking position. Publishes only signals that cannot be bought: verification state, listing age, first-party referred visits, declared repository stars.
Harpd Model Pricing Dataset
One record per model with input/output token price, the official provider pricing page it was read from, and the date it was verified.
Harpd Benchmark Dataset
Long-format benchmark records (model, task, metric, score, cost, timestamp) with an explicit isModeled flag separating measured runs from modeled estimates.
Harpd Methodology Dataset
Machine-readable export of the Harpd Rank rules, boards, entry conditions and disclosure.
Citing a single number
Prefer the most specific object you can. Link the product profile for a product claim (every record carries a canonical url), the methodology page for a rule, and the dataset for an aggregate. State the as of date alongside the figure — the boards move, and a dated claim stays verifiable after they do.
- Quote the value together with its unit and the date it was current.
- Link the methodology once, so a reader can see how the number was produced.
- Rank Points are promotional placement. Describe them as placement, never as a quality score, rating or review.
- Modeled estimates are labeled estimated in the data. Keep that word when you quote them.
What Harpd does not claim
Publishing the boundary is part of being citable. These are statements we deliberately do not make, because the data behind them does not exist.
That any model is "safe to switch to" for a production workload.
A switch decision requires a real-task quality gate on the specific workload. No dataset covers that yet.
We publish the method, not a result.
That a higher-ranked product on Harpd Rank is a better product.
Rank Points are promotional placement bought with Credits. Harpd holds no quality measurement that would support an ordering by merit.
Monthly visit counts or user review scores for listed products.
Harpd has no first-party measurement of third-party traffic or reviews, and does not republish vendor-supplied figures as facts.
The non-sponsored signals Harpd can verify are published in /data/rank-open-data.json instead.

Method
Every citation on this page is generated from the canonical dataset registry in code, not written by hand. A dataset becomes citable only when it has a published endpoint, a methodology page, a stated update cadence and a stated coverage — a new endpoint cannot quietly become a source without all four.

Data
- /data/rank.json — Harpd Product Ranking Dataset
- /data/rank-history.json — Harpd Historical Ranking Dataset
- /data/products.json — Harpd Product Directory Dataset
- /data/categories.json — Harpd Category Dataset
Limitations
- A dataset with no machine-readable timestamp shows no "as of" date; the date is not estimated.
- Coverage is per dataset. A board-wide figure does not transfer to a single product or category without re-deriving it.
- CC BY 4.0 requires attribution and does not imply endorsement of you or your work by Harpd.
