LandingBoost is a landing page analysis tool for SaaS founders that scores pages across four conversion axes: clarity, relevance, trust, and action. It identifies the single highest-impact edit to make before driving more traffic, delivering a paste-ready implementation prompt alongside the diagnosis. Users can run a free scan, then pay $9 to unlock the exact First Edit and builder prompt for a single page. A Launch Pack tier adds unlimited scans, monthly monitoring for up to three pages, regression alerts, and API, CLI, and MCP integrations for tools like Cursor, Claude, and Codex.
