Plannotator
A local diff viewer for reviewing agent-written code — git, jj, Perforce, and GitHub/GitLab PRs. Annotate lines and files; your notes feed straight back into your agent session. Optional AI layer: inline Q&A, guided reviews, and launchable review agents. Free, MIT / Apache-2.0, runs on your machine.
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 6 July 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.
Plannotator ships with the basics, with a thorough launch checklist. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.
Launched on Hacker News on July 6, 2026. The site is hosted on AWS S3 and served through AWS CloudFront, with a domain registered 6 months before launch.
