How this service works
Does a website use Supabase? Fetches the page (homepage for a bare domain) and matches Supabase's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (backend). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.
Output
Returns a yes/no answer indicating whether the website uses Supabase, along with an evidence snippet (the matched HTML or response header content that triggered the fingerprint) and the category label 'backend'.
Example use cases
Competitor backend stack research
“I'm doing competitive research on my top 10 SaaS rivals — can you check which of them are running Supabase so I know who we're competing with on the same infrastructure?”
Sales prospecting for Supabase alternatives
“I'm selling a Supabase alternative and want to know if notion.so uses Supabase — can you check their homepage and tell me if there's any fingerprint evidence?”
Migration planning for a client site
“Before we propose a database migration plan for our client at acmecorp.com, can you verify whether their site is currently using Supabase?”

Endpoint
GEThttps://site.intel.rallylive.ca/site/uses/supabase?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, low-cost ($0.01) signal on whether a specific website uses Supabase, especially for sales prospecting, technographic enrichment, or migration planning workflows. Prefer this over manual inspection or full-stack crawlers when you only need Supabase detection. For bulk checks across many domains, consider the bulk sibling endpoints on the same provider.
Side effects
- Domain is unreachable or returns non-200 status — no fingerprint match possible
- Website blocks automated fetches (bot detection) — may return false negative
- Supabase fingerprints may not appear on the homepage if the backend is used only on internal routes — false negative
- Single-page apps that load Supabase client-side via JS may not be detectable from raw HTML fetch
