Change watch
What this board tests: change detection / monitoring on a url. Every provider below ran the identical corpus on 2026-06-21. The composite blends measured quality, latency p50, cost per successful call and error rate. Method and corpora: how we measure.
| Rank | Provider | Composite | Class. accuracy | Cost | Latency p50 | Field note |
|---|---|---|---|---|---|---|
| 1 |  Firecrawl |
8.33/10 | 1.00 | $0.001 / call | 3.0 s | Uniquely offers synchronous change detection. |
Low scores are published alongside high ones — a ranking you can only trust if nothing gets hidden. The gateway's fee sits on top-ups, not per call, so the order above earns us nothing either way.
