I built SiteBlob because fast-built websites can look finished and still lose trust
A pattern kept showing up while I was looking at new SaaS sites and AI-built landing pages.
The site would look polished at first glance, but something felt off after a minute or two. No founder context. Thin proof. Policy pages that looked copied in at the last second. Claims without sources. Sometimes the copy had that same AI vibecoding fingerprint where everything sounds clean but nothing feels anchored.
That matters more than people admit. A buyer does not always say “I do not trust this.” They just close the tab.
So I built SiteBlob as a quick credibility scan for founders, agencies, and product teams before launch traffic starts coming in. It looks for trust signals, policy gaps, source citations, founder or author context, content originality cues, and AI vibecoding signals. The scan is not meant to shame a site or pretend every signal is proof. It is a checklist for things worth fixing before strangers see the page.
The main use case is simple: before Product Hunt, paid ads, SEO outreach, or a client handoff, run a scan and clean up the parts that make the site feel less real than it should.

I would be curious what trust signals you check before launching a new site.
Trust signals we see consistently stalling launch conversions: lack of named attribution (testimonials without full names, revenue claims without logos, "used by 500+ founders" without any faces), hero copy that describes the tool's features rather than the outcome the buyer gets, and policies that appear in the footer but nowhere near the primary CTA.
The one I'd add to your scan: the gap between trust signals and conversion signals. A site can be completely trustworthy — real founder bio, proper policies, clear pricing — and still fail because the trust sits too far from the purchase moment. "Book a call" buried under a testimonial nobody reads.
SiteBlob's credibility lens and a conversion-focused scan are probably more complementary than overlapping. We built something that runs the conversion/performance side — might be interesting to see where the two scans diverge on the same URL: https://outboundautonomy.com/grade?ref=ih-siteblob
This is a real problem, especially with AI-built SaaS sites.
The interesting angle is that SiteBlob should probably not be positioned as a generic “website trust scanner.” That sounds useful, but a bit broad.
The sharper wedge is launch risk.
Before Product Hunt, ads, SEO outreach, or a client handoff, founders and agencies want to know: “Will this page feel real enough for strangers to trust it?”
That is more urgent than just improving credibility in general.
I’d also separate trust signals into two buckets:
surface trust: founder context, policies, proof, testimonials, sources
conversion trust: does the claim feel believable enough for someone to start a trial, book a call, or keep reading?
That second bucket is probably where SiteBlob can feel more valuable than a checklist.
Happy to put a tighter version in writing if useful. I’d map the strongest first buyer segment, positioning angle, and how I’d test the first 20 users without making it too broad.
