PurpleSign — Send documents for signature. Compliant where it counts.
This site was found by StackScope Discovery, our own
first-party launch detection. The tech stack below comes from that
discovery scan; the full analysis (screenshots, scores, page checks)
is added when the site is picked up by a launch platform.
E-signatures designed and tested against 21 CFR Part 11. Tamper-evident audit trails, completion certificates, and unlimited envelopes on every paid tier. Now in pilot.
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 24 July 2026; the live site may have changed since.
