Production FastAPI + Next.js foundation for SaaS builders
4 followers
The Fabrica is a production FastAPI + Next.js SaaS foundation for builders who don't want their coding agent to rediscover auth, billing, credits, workers, migrations and lifecycle from scratch. The architecture, boundaries, invariants and 49 practical recipes are already documented so you can start with production context, not just starter code. Built especially for AI-heavy products with async work and metered usage. $379 Solo / $749 Team.
Hey Product Hunt 👋
I built The Fabrica because I got tired of spending the first few weeks of every SaaS rebuilding the same production layer.
Auth. Billing. Credits. Workers. Migrations. Account lifecycle. Deployment config. And then all the failure modes between those pieces.
There are already plenty of SaaS boilerplates, and coding agents can generate starter code very quickly now. So if the value were just “here are some files”, I don’t think this product should exist.
The bet behind The Fabrica is different:
the valuable part is the production decisions, integration work, verification, and context that you can hand to your coding agent instead of rebuilding them every time.
The stack is deliberately opinionated:
FastAPI + Next.js + Postgres + Celery/Redis + Paddle
It’s particularly aimed at SaaS products with AI, async work and metered usage.
The repo also includes:
deep architecture and implementation docs
explicit product-specific _domain/ boundaries
49 practical recipes
an AI-oriented guide to the codebase
documented invariants, failure modes and tradeoffs
It is deliberately designed to be worked on with coding agents.
As code generation gets cheaper, the valuable part moves from generating files to giving the agent the right architecture, boundaries, invariants, failure modes and verification context from the start.
So the idea isn’t “buy this instead of using Claude.”
It’s: give Claude a production foundation instead of asking it to rediscover one from scratch.
Before releasing it, I forced the buyer path through fresh-clone and real sandbox checks. That process found bugs the existing test suite had missed, including a Paddle webhook concurrency race.
I know trust is probably the hardest part when selling a private codebase, so you can inspect the claim before buying:
there’s an 81-second walkthrough recorded from the exact release tag
a public inspection repo with representative code, tests and docs
Scribora is the real product the foundation was originally extracted from
Pricing is one-time:
Solo — $379
Team — $749
I’d especially like feedback from Python/FastAPI builders:
is “I can build this, but I don’t want to rebuild and re-validate it again” a strong enough reason to buy a foundation like this?
Thanks for taking a look.
