Add custom fields to your SaaS product without building the infrastructure. Embeddable field editors, REST API, TypeScript SDK, and MCP server for AI agents.
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 29 April 2026; the live site may have changed since.
Kopra - Custom Fields as a Service looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on PeerPush on April 29, 2026. The site is hosted on HETZNER-AS in Germany, with a domain registered 4 weeks before launch.
