The .0n App Marketplace

# The .0n App Marketplace The `.0n` format was always built for portability — apps that run anywhere AI runs. The Marketplace is where you find them. ## What's in the Marketplace - **First-party 0nCore products** — Course Builder, Lead Magnet Loop, Landing Pages, SXO Indexer, Automation Builder, and more. - **Community apps** — anything published by a vendor. Same `.0n` format. Same install flow. - **Agency packages** — bundles of apps + workflows + snapshots ready for sub-account deployment. Everything is plan-aware. If a customer's plan doesn't cover an app, they see the upgrade path. If it does, install is one click. ## Iframe widget The Marketplace ships as a `/widgets/marketplace` widget that any AI surface can embed. Drop it in a CRM dashboard, Chrome extension, Slack canvas — everywhere it renders, install + checkout work the same way. ## Built on UCP The Marketplace catalog is a UCP view. Free apps install via `marketplace_install`. Paid apps go through `marketplace_checkout` (Stripe). Both write to the same purchase + entitlement tables, so the customer sees one history regardless of where they bought. Lands in v4.10.0. Public availability for 0nCore: May 1, 2026.
