Mastros — LinkedIn & Sales Navigator
Save LinkedIn and Sales Navigator searches as CSV, JSON or JSONL — profiles, companies, jobs, posts, leads and accounts. It only reads, it runs in your browser, and it never guesses emails.

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 1 August 2026; the live site may have changed since.
Mastros — LinkedIn & Sales Navigator ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on August 1, 2026. The site is served through Cloudflare. The crawl picked up 15 technologies on this site, covering analytics, ui library, CDN, and CSS frameworks. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.
For context, it's running the same core stack as 6,546 other launches.
