Superliner Notes (Beta)
Superliner is a native graph outliner for the Mac: notes nest in an outline, every note opens as its own page, and notes link to each other. Your notes stay in files on your Mac.

What we found
- Analytics set tracking cookies before any opt-in, and we found no consent manager.
- It sends two of the six security headers we check; Content-Security-Policy is among those missing.
- DMARC only monitors (p=none), so email spoofing this domain is still delivered.
- Built with Next.js and React, the site is hosted on Vercel and served through Cloudflare.

Looks AI-built: some AI signals.
How much the site looks AI-generated. It is a pattern match shown for interest, not a verdict.
Which signals fired
Signal Points AI CSS signals +10 AI onboarding signals +5 AI palette signals +5 AI writing signals +3 AI stack signals +10 - Analytics set tracking cookies on our visit and no consent manager was detected. UK and EU GDPR require opt-in before tracking runs, and more than 20 US states require honouring opt-out requests.
- Performance comes from one render on 8 November 2026 and will vary between visits.
How we know
FirstSited records what new websites are built with, usually within a day of going live. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We checked this one in full: its tech stack, DNS, security headers and page basics. This page is what we saw on 8 November 2026; the live site may have changed since.
Every technology below links to its own page: which other new sites launched with it. Watch any of them and get every new site that uses it as it goes live, from £15 a month.
