The problem

Documentation is the tax every team pays

Teams ship fast — and the docs never keep up. Within weeks the wiki is a lie, onboarding drags, and the real architecture lives only in a few people's heads.

Docs rot instantly

Hand-written documentation is obsolete the moment the next commit lands. Nobody trusts it, so nobody updates it.

🧠

Onboarding takes weeks

New engineers reverse-engineer the system by hand — asking around, reading code, rebuilding the mental model from scratch.

🗺️

No one sees the whole system

Services, databases and queues connect in ways no single diagram captures — until something breaks in production.

The speed
≈1 second

Point Cruderra at your Java, Python or Go repository and get full documentation and architecture diagrams in about a second — not the weeks it takes to write them by hand.

How it works

From code to living docs — automatically

STEP 01

Connect your repository

Point Cruderra at your Java, Python or Go codebase. It reads the source directly — no manual modelling.

STEP 02

Your system, mapped

Cruderra reconstructs the architecture — components, databases, queues and the links between them — in about a second.

STEP 03

Always-current documentation

Docs and diagrams are generated as code, versioned in Git, and refreshed on every commit.

What you get

Documentation that keeps itself up to date

🔗

Live architecture graph

An interactive map of services, data stores and dependencies, rebuilt from the real code.

📐

C4, DFC & UML diagrams

Generate standard architecture and data-flow diagrams straight from your repositories.

🧾

OpenAPI & AsyncAPI export

Export machine-readable API specifications for your services in a click.

📚

Docs-as-Code

Documentation lives in Git next to your code and is reviewed like any other change.

♻️

Re-scans on every commit

Docs and diagrams stay in sync with the codebase — no manual updates, ever.

Java, Python, Go

Built for real enterprise stacks — with more languages on the way.

Before / after

Stop writing docs by hand

Documentation by hand

  • Takes days — and is outdated by the next sprint
  • Diagrams drawn manually, then forgotten
  • Onboarding measured in weeks
  • Architecture lives in people's heads

With Cruderra

  • Full docs generated in ≈1 second
  • Diagrams rebuilt from real code on every commit
  • Onboarding in a day, not weeks
  • The whole system, on one canvas
