The Posting Substack API
The posting API for Substack authors. Draft, publish, and schedule posts via Python SDK, CLI, or MCP — without the browser editor.
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 28 July 2026; the live site may have changed since.
The Posting Substack API is partway there, with clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and no email security records.
Launched on Hacker News on July 28, 2026. The site is hosted on OpenNext and served through Cloudflare, with a domain registered the day of launch. The crawl picked up 9 technologies on this site, covering baas, CDN, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
For context, it's running the same core stack as 764 other launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
