AI coding agents shifted something: one person can now build an internal tool that solves a real problem in days. Most of those tools stop right there. No distribution, no compliance, no checkout, no audience. Not because the tool is bad, but because turning software into a product is a second, entirely different job.
That second job is what the marketplace does. Every System listed here was itself built with AI assistance, audited, and listed with its report published. Yours can be next.
