GGutencode

The printing press for codebases.

Gutencode prints a production backend — auth, tenancy, payments and more — audited and tested in Python, Go & Node. You / Agent add your custom 10% to launch your app.

the honest part

Why spend weeks on the foundation?
Agents hallucinate. We print it right.

The boring 90% of a backend is the same every time. We print it — you and your agents add the 10% that's actually yours.

vibe coding

  • Hallucinated CRUD that almost compiles
  • Context lost after 400 lines
  • One change quietly breaks three files
  • Auth rewritten (badly) for the 47th time
  • “It looked good in the chat”

the press

  • Structural 90% composed, never guessed
  • Reproducible — same spec, same fingerprint
  • Money/identity/tenancy ship invariant-tested
  • A red audit is a real, located bug
  • A labelled map of exactly where your code goes
the proof

Yes — we print code.
See it for yourself.

Read every line
No black box in what you get. It's clean, idiomatic code a senior dev would sign off on — yours to read top to bottom.
Clone it & run it
docker compose up. Green tests. A real read-back against Postgres. It boots — on your machine, not in a demo video.
Reproducible
Same spec in, identical code out — byte-for-byte. No dice rolls, nothing hand-tweaked behind the curtain.
Same in 3 languages
Python, Go and Node — proven to behave identically. That's not something templates or a lucky prompt can fake.

Don't believe us. Read one.

Every output ships as a complete, runnable repo on GitHub — audited, unit-tested, multi-language. Open one and decide for yourself. That's the only proof that matters.

Read a generated backend
what comes off the press

Set it once. A backend a senior dev would be proud of.

Set the type once. In seconds the press pulls a production-shaped, audited, reproducible backend — in the language you want — and hands you the keys to the part that's actually yours.

Deterministic + audited

Seven hard gates plus config-generated conformance checks run before you ever see the code. A red is a real, located bug — not a vibe.

The hard domains, proven

Money, identity and multi-tenancy ship invariant-tested: a ledger that proves debits == credits, auth that proves no-plaintext & deny-by-default, an agent loop that provably terminates.

Complete on day 1 — then customize

Not a skeleton with gaps to fill. You get 100% working, audited, unit-tested code with sensible defaults. A CUSTOMIZE guide points at the exact lines to change for your business rules — you edit working code against a green baseline.

Swappable adapters

LLM keys, queues, payments, storage — all behind ports. Swap providers from .env. No vendor lock-in, fully offline-testable with fake adapters.

One backend, three languages

Idiomatic, parity-matched code in Python, Go & Node — proven to behave identically across all three. The same spec always prints the same code: byte-for-byte reproducible, every time.

Production-shaped

Clean folders, RFC 9457 errors, a migrating schema, Docker + Railway artifacts, OpenAPI, and a self-documenting SETUP.md. Boots and read-backs against real Postgres.
