Comparisons

The Fabrica vs Open SaaS

A free, MIT-licensed SaaS template on the Wasp framework, against a paid Python foundation built around production semantics.

Last reviewed · from Open SaaS’s own site and documentation

The short answer

Choose Open SaaS if

you want to start at zero cost with something complete and MIT-licensed, your team is JavaScript, and one process is the operational ceiling you want.

Choose The Fabrica if

metered usage is the product rather than a trial allowance, your backend is Python, and you want the production decisions written down and tested.

At a glance

The dimensions a decision turns on

Twelve rows, not forty. Every answer about their product is numbered and links to the page it came from, so you can check it rather than trust it.

Backend
The FabricaFastAPI and async SQLAlchemy 2.0, in Python.3
Open SaaSNode.js, expressed through the Wasp framework: a config file declares auth, routes and jobs, and Wasp generates the wiring around your code.1
Frontend
The FabricaNext.js and React, with Tailwind and next-intl. One web surface.3
Open SaaSReact, in the same Wasp project as the server.1
Data layer
The FabricaPostgreSQL with Alembic migrations. Redis is the Celery broker.3
Open SaaSPostgreSQL through Prisma, which also owns migrations.1
Source model
The FabricaA commercial source licence. You get the repository and own what you build in it; it is not open source.1
Open SaaSOpen source under the MIT licence. The whole template is public and forkable, with no purchase and no licence key.6
Pricing
The FabricaSolo $379, Team $749. One payment, not a subscription.1
Open SaaSFree.6
Payments
The FabricaPaddle, acting as merchant of record, so sales tax is filed by the provider rather than by you.8
Open SaaSStripe, Lemon Squeezy or Polar, each with its own integration guide.2
Background work
The FabricaCelery workers on Redis, deployed as their own process, with scheduled beat tasks and a reconciler that repairs missed state.5
Open SaaSWasp jobs, executed by pg-boss and persisted in Postgres, with cron scheduling. Their docs: “PgBoss runs together with your web server … it is not a separate process or service, but rather a part of your web server’s application.”5
Usage and credits
The FabricaAn append-only credit ledger: every movement is one INSERT and the balance is derived, so concurrent spends and refunds reconcile.4
Open SaaSCredits are an integer field on the user — credits Int @default(3) — giving new users a trial balance, with a one-time top-up plan in the template.3
Coding-agent context
The FabricaOne canonical instruction file at the repository root, reachable from AGENTS.md and a Cursor rule, plus 49 decision recipes an agent can read instead of guessing.7
Open SaaSPositioned as “built for the AI era”, with Wasp’s abstractions and opinionated defaults plus custom agent rules, skills and tools.1
Extension model
The FabricaReserved _domain/ directories: upstream does not overwrite the files you create there, which shrinks the surface an update can collide with rather than removing it.6
Open SaaSYou fork the template and edit it directly. Wasp’s config file is where auth, jobs and routes are declared; the rest is ordinary React and Node.2
Deployment assumptions
The FabricaDocker Compose locally. Postgres, Redis and a separate worker process are assumed to exist wherever you deploy.5
Open SaaSWasp's one-command deploy to Fly.io or Railway is the documented quick path, with manual deployment to any other provider.4
What you can read first
The FabricaPublished engineering documentation, a public inspection repository, and a walkthrough recorded from a release tag.9
Open SaaSThe entire product is the proof: the repository is public and MIT-licensed, so you can read every line before deciding.6

Philosophy

What each one is optimising for

Feature tables compare what two products contain. This is the part that decides whether either fits: what each one decided to be good at, and what it gave up to be good at it.

Free, and framework-shaped

Open SaaS is free and MIT, and that is not a detail to route around on the way to a sales argument. It changes the decision structurally: you can read all of it, run all of it, and abandon it having lost a weekend rather than a licence fee. Nothing on a paid page competes with that on risk.

Its second idea is Wasp. Auth, routes and jobs are declared in a config file and the framework generates the wiring, which removes a large amount of glue and keeps the whole app in one project. Jobs are the clearest example: pg-boss persists them in Postgres you already run, and their docs are explicit that it lives inside the web server rather than beside it. One process, one deploy, jobs that survive a restart.

The trade is that you are inside a framework's opinions rather than a library's. When Wasp has an answer, you get it almost free. When your requirement is outside what Wasp generates, you are working with the framework rather than simply writing Node.

Paid, and semantics-shaped

The Fabrica costs money, so it has to be worth more than free — and “more features” is not the argument. The argument is the specific production semantics around money, jobs and personal data, and the fact that they are documented as decisions rather than left as code to reverse-engineer.

Credits are the sharpest illustration, and the difference is in the data model rather than in the quality of either implementation. Open SaaS stores a balance: credits Int @default(3) is a field that says how many a user has left, which is exactly what three free generations and a top-up plan need. The Fabrica stores movements: each grant, spend and refund is its own row, and the balance is their sum.

A balance answers “how many are left”. A ledger answers that too, and also “where did they go” — the history a dispute, a refund or an audit is settled from. Neither is a defect; they are two reasonable answers, and the second costs more to build and to query. We pay that because metered usage is a first-class product concern here rather than a trial allowance, and the reasoning is published rather than asserted.

The same shape repeats. Long work goes to a Celery worker in its own process, which is more to operate than pg-boss and buys isolation from the request path. Webhooks ride idempotency tables because a payment provider retries for days. None of it is free, in money or in operations.

Fit

Who should choose which

Choose Open SaaS

Open SaaS is the stronger choice when:

  • Budget or risk tolerance says start free. It is MIT, it is complete, and you can read all of it before committing anything.
  • Your team is JavaScript and TypeScript, and a Python service would be the only Python service you run.
  • Wasp's model appeals — declaring auth, routes and jobs in a config file removes real glue, and one project is genuinely simpler than two.
  • One process is the operational ceiling you want. Jobs inside the web server means nothing else to deploy or monitor.
  • You want to modify the foundation itself without a licence deciding what you may redistribute.

Choose The Fabrica

The Fabrica is the better fit when:

  • Metered usage is the product, not a trial allowance, and you need refunds and concurrent spends to reconcile.
  • Your backend work is Python-shaped, and FastAPI with async SQLAlchemy is where you want to write it.
  • Long jobs need to be isolated from the request path — CPU-heavy work in the web server is the case pg-boss's own documentation warns about.
  • You want the reasoning, not just the code: why the ledger is append-only, why webhooks are idempotent, what erasure actually deletes.
  • You would rather buy the compliance surface — audit log, cascade erasure, processing register — than assemble it later under time pressure.

Still deciding?

Read the code before you read the price. If it is not the right foundation for what you are building, Open SaaS is a good product and this page has tried to say why.
