How this service works
Does a website use LaunchDarkly? Fetches the page (homepage for a bare domain) and matches LaunchDarkly's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (feature-flags). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.
Output
Returns a yes/no boolean indicating LaunchDarkly presence, an evidence snippet showing the matched fingerprint (HTML or header content), and the technology category label ('feature-flags').
Example use cases
Sales prospecting for LaunchDarkly competitors
“I'm doing sales outreach for a feature flag management tool — can you check if stripe.com is already using LaunchDarkly so I know how to position my pitch?”
Competitor technology stack research
“I'm researching our top 5 competitors and want to know if any of them use LaunchDarkly. Start with shopify.com — does their website show signs of LaunchDarkly?”
Pre-migration technology audit
“Before we start our migration project, can you verify whether our client's site at example.com currently has LaunchDarkly deployed? I need to know if we have to account for it in the migration plan.”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/uses/launchdarkly?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, single-domain check specifically for LaunchDarkly presence — ideal for sales qualification, competitor research, or migration audits. Prefer this over general tech-stack scrapers when you only care about feature flagging tools and want low-cost ($0.01) per-domain results. For broader technology detection across multiple categories, consider combining with sibling endpoints.
Side effects
- Target website is unreachable or returns an error — check will fail to return a definitive result
- LaunchDarkly loaded via a tag manager or delayed script injection may not be detected on initial HTML load
- False negative if LaunchDarkly is only used on authenticated pages not accessible to the crawler
- False positive risk is low but possible if another tool mimics LaunchDarkly's fingerprint patterns
- Rate limiting or bot-blocking by the target site may prevent the page fetch
