HTPBE PDF Tamper Detection API
One edited bank statement costs $15K–$50K in bad debt. The structural PDF layer Plaid and Persona don’t cover. Self-serve REST API from $15/mo.
StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 25 June 2026; the live site may have changed since.
HTPBE PDF Tamper Detection API scores well across the board, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: tracking cookies set before any opt-in.
Launched on PeerPush on June 25, 2026. The site is hosted on Cloudflare in the United States. The crawl picked up 21 technologies on this site, covering advertising, analytics, auth, and CDN. The stack includes Auth.js, Next.js, and React.
For context, it's on one of the most common stacks we track, shared by 2,991 launches and more locked down than the typical PeerPush launch.
