Four checks. One launch score.
LaunchCheck focuses on practical issues that are easy to miss just before a site goes live. It is intentionally narrow: useful pre-launch signals, not a fake “everything score.”
Social previews
Open Graph title, description and image, plus Twitter/X card metadata.
Security headers
HTTPS, HSTS, CSP, MIME sniffing protection, referrer policy and permissions policy.
Technical readiness
HTTP status, mobile viewport, language, favicon, response timing, HTML type and JSON-LD.
Designed to work inside ChatGPT.
LaunchCheck includes a read-only MCP plugin. Once connected, users can ask ChatGPT to scan a public website and explain what to fix.
MCP endpoint: /api/mcpExample prompt
“LaunchCheck, check https://example.com before I publish it. Show me the most important fixes first.”
