Choosing the wrong crawler mode is one of the fastest ways to produce noisy findings. This guide compares browser and static crawl modes so teams can run higher-confidence checks and publish evidence responsibly.
Mode selection in the current product
VeriFalcon already exposes separate crawl entry points for JavaScript and static surfaces.
JavaScript mode captures JS/API failures and rendered route outcomes.
Static mode provides faster throughput on docs/blog/HTML-first surfaces.
Both modes share report framing for broken pages/resources and route coverage context.
The key decision is not which mode is 'better' overall; it is which mode matches the route behavior you need to verify.
Current Crawler Mode Surfaces
Choose browser crawling when
- routes depend on hydration or client navigation
- important pages are behind login
- you need JS-error or API-failure visibility
- soft-404 behavior appears after runtime rendering
Choose static crawling when
- the target is docs, blog, or mostly static pages
- high page-volume speed is required
- runtime JS behavior is not central to route health
- you need a lightweight baseline pass before deeper browser checks
Reporting and publicity guidance
When sharing findings publicly, disclose crawl mode and scope. A static-crawl finding should not be framed as full runtime app coverage, and browser-crawl findings should still be framed as point-in-time quality checks.
This keeps outreach credible and reduces backlash from overbroad claims.
