Show HN: I built an AI agent to yell at me about my ADHD

Added June 30, 2026 · Last analysed June 30, 2026 · via Hacker News · 40% unique tagline (similar to Which AI agent are you?)

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 30 June 2026; the live site may have changed since.

0xff is early-stage. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on June 30, 2026. The site is hosted on High5! B.V. in the Netherlands. We've detected 2 technologies on this site, covering business email and social embeds. The stack includes Bluesky and Fastmail.
