Libretto PR agents
Automatically investigate failing Playwright scripts against the live page and open a GitHub pull request with a proposed fix.
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 17 July 2026; the live site may have changed since.
Libretto PR agents has the basics covered well, with a complete set of security headers, a thorough launch checklist, and clean crawl signals. What needs work: incomplete legal pages and incomplete email security.
Launched on Hacker News on July 16, 2026. The site is hosted on Vercel. Our crawler found 14 technologies on this site, covering transactional email, javascript library, analytics, and CSS frameworks. The stack includes Tailwind CSS, TanStack Start, and Amazon SES.
It's also one of 67 launches on this exact stack and tighter on security headers than most Hacker News launches.
