Settings & Limits

Rate limits

Action	Limit
Single-page scans	10 per hour per IP
Full-site crawls	1 running at a time per site
Concurrent page scans (per crawl)	3 (server-side, not configurable in UI)

Rate limits reset every hour. If you hit the single-page scan limit, you can still start or continue a full-site crawl — crawl-initiated scans bypass the IP rate limit.

Page cap

If the ClearSight instance has MAX_CRAWL_PAGES configured, crawls will stop after that many pages. Check with whoever hosts your ClearSight instance.

You can also set a per-crawl page cap when starting a crawl from the UI.

What affects scan accuracy

Factor	Impact
JavaScript-rendered content	Included — ClearSight uses a real browser
Lazy-loaded content	Partially included — content must be in the DOM at load time
CSS-hidden elements	Checked — hidden elements can still fail accessibility rules
Dark mode / forced colors	Not tested — scans use default browser settings

Scan timeout

Individual page scans time out after 30 seconds. Pages that time out are marked as failed and don’t count toward the overall score.
