Show HN: penguinAI – the c.ai alternative focused on privacy, no self-hosting

AI

Added June 17, 2026 · Last analysed June 17, 2026 · via Hacker News

StackScope records what new websites are built with, the week they launch. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We crawled this one for its tech stack and scored it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 17 June 2026; the live site may have changed since.

Every technology below links to its own page: which other new sites launched with it. Vendors and agencies watch those pages with Stackdar and hear about new adopters the week they ship, from £15 a month.

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

Launched on Hacker News on June 17, 2026. The site is hosted on AWS ALB and served through Cloudflare. We've detected 6 technologies on this site, covering ai service, CDN, DNS providers, and web fonts. The stack includes AWS ALB, Cloudflare, and Cloudflare DNS.

It's one of 38 launches on this exact stack.
