Cursor has MCP Marketplace with team-level plugin sharing. Factory.ai is model/tool agnostic and extensible. Replit has a large community gallery. SaaS Factory has 32+ specialized agents that are entirely internal — there is no way for users to share custom agent configurations, custom pinned specs as templates, or custom discovery agent prompts. The codebase has pinnedSpecs, pipelineConfig toggles, and agentPersona definitions that could form the foundation of a marketplace. A public marketplace creates a viral growth loop (users share configurations → new users discover SaaS Factory), a community moat, and potential for a paid 'pro agent packs' revenue stream.
