A new Flutter project.

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.

stem_sketch_pad is missing several launch fundamentals. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 30, 2026. The site is hosted on Firebase Hosting and served through Fastly. Our crawler found 7 technologies on this site, covering auth, baas, CDN, and frameworks. The stack includes Flutter, Google Sign-In, and Fastly.

It's also on a stack we've seen on only 6 launches.
