The production-ready marketplace
Curated SaaS kits, AI app kits, landing pages and agent skills — inspected, maintained and license-clear. Skip the months spent rebuilding auth, billing and multi-tenancy, and launch on a foundation you can trust.
Build products to sell? Sell your work
Production-ready code
Built to ship, not just to demo. Real stacks, real structure.
Clear licensing
Know exactly what you can build and ship before you buy.
Maintained products
Versioned releases and changelogs, not abandoned templates.
Live previews
Inspect the real thing before committing to a purchase.
Agent-ready docs
Documentation structured for coding agents and humans alike.
Start from a category and narrow down by technology and use case.

Get production-ready code and agent-ready docs. Customize with your stack — or your coding agent.
Maintained products ship versioned updates and changelogs, so what you launched on keeps improving.

Launch an AI product with auth, billing hooks and a usage-metered API layer already wired.
A clean foundation for subscription products: row-level security patterns and checkout flows included.
Organizations, members and per-tenant data isolation, structured so you can extend it safely.

FAQ
Licensing, updates and how buying compares to a subscription.
Products are built on real, modern stacks with sensible structure, documentation and licensing — intended to be launched on, not just demoed. Each product page will show its technologies, license and a live preview.
Every product states its license clearly before purchase — typically personal, commercial, agency or extended tiers. You choose the license that matches how you intend to ship.
You can buy individual products outright, or subscribe to Pro to access platform-owned libraries and their ongoing updates. Pro is recommended once several platform-owned products are relevant to you — we never lead with the subscription.
Yes. Products include agent-ready documentation so you can extend and customize them with coding agents as well as by hand.
Maintained products ship versioned releases with changelogs. The “latest releases” feed reflects that cadence — the entries shown today are illustrative examples while the catalog is being built.
That is the plan. Sellers will be able to publish free and paid products, set licenses and receive payouts. Seller onboarding and verification arrive in a later phase.
Illustrative feedback
Assetzaar helps SaaS founders, agencies and AI builders launch production-ready products in days, not months — with maintained kits, clear licensing and live previews. These examples reflect the outcomes the marketplace is built to deliver.
“Bought the complete AI SaaS Starter and had auth, billing and multi-tenancy live in a weekend — a whole month of foundation work, gone.”
“I only needed a landing page. Grabbed one polished system, swapped the copy, and launched our waitlist the same afternoon.”
“Picked up an agent skill that automates our PR reviews and dropped it straight into my coding agent. No glue code.”
“Started with a free resource just to test the quality. It was so clean I bought two premium kits the same week.”
“The Gmail automation kit replaced a manual triage process my team had dreaded for months. Adapted it to our stack in an evening.”
“Bought just the Supabase + Stripe starter. Row-level security and checkout were wired exactly how I'd have done them.”
“Grabbed a dashboard kit and shipped an internal admin panel in two days. Clear license meant I could use it for the client.”
“Used the marketplace starter for a client, then reused its UI components across three more projects. Easily paid for itself.”
