# The Fabrica > A production FastAPI and Next.js SaaS foundation, licensed once: authentication, billing, credits, background work, account lifecycle and the compliance surface are already built and tested, and the buyer extends them for their own product. This file maps the commercial and evaluation surfaces of The Fabrica's storefront. The engineering documentation is a separate site with its own index; both are listed below. ## Product - [The Fabrica](https://www.thefabrica.dev/): What the foundation is and who it is for. - [Pricing and licence](https://www.thefabrica.dev/pricing): One-time licence in two tiers, not a subscription. Sold through Paddle as merchant of record. - [Under the hood](https://www.thefabrica.dev/under-the-hood): The technical case: source excerpts with the repository paths they came from, and verification numbers a buyer can reproduce. ## Comparisons Each comparison is written from the other vendor's own site and documentation, carries the date it was last read, and cites a first-party source for every fact about them. Where something could not be established from public material the page says so, which is a statement about the review rather than about the product. - [Comparisons](https://www.thefabrica.dev/compare): Hub. Which starter fits which founder, and how these pages are sourced. - [The Fabrica vs Hype Stack](https://www.thefabrica.dev/vs/hype-stack): A composable TypeScript application platform that reaches five surfaces, against an opinionated Python foundation that goes deep on one. Last reviewed 2026-09-10. - [The Fabrica vs Open SaaS](https://www.thefabrica.dev/vs/open-saas): A free, MIT-licensed SaaS template on the Wasp framework, against a paid Python foundation built around production semantics. Last reviewed 2026-09-10. - [The Fabrica vs ShipFast](https://www.thefabrica.dev/vs/shipfast): A Next.js launch kit tuned for getting an online business live quickly, against a Python foundation tuned for what happens after it is. Last reviewed 2026-09-10. ## Engineering detail - [Engineering documentation](https://docs.thefabrica.dev): The reasoning behind the product, extracted from its own documentation and versioned. Has its own llms.txt. - [Public inspection repository](https://github.com/webrot9/thefabrica-inspect): Selected real files — a scaffolded resource, the IDOR regression test, a concurrency transcript. Not the product source, and not open source.
