Subak
The trust layer for AI code

AI writes the code. Subak checks it does what you meant.

It checks AI-generated code against what you set out to build, then shows you what's solid and what's about to break.

Start where you are

What you need from Subak depends on what you're building.

See your architecture

Your whole codebase, in one view.

Subak maps your project into a dashboard you can read at a glance, so you can see how everything connects even if you didn't write a line of it. You see in one picture what's normally buried across a hundred files.

Why Subak

Green checkmarks aren't proof.

Everything you already run checks one piece. None of it checks whether the whole thing does what you set out to build.

Tests, linters & review
what they check

One piece at a time.

  • The paths someone remembered to write a test for.
  • Local rules, types, and syntax, one file at a time.
  • Green stays green even when the feature isn't the one you asked for.
  • Whatever a senior has time to read before the next thing ships.
Subak
what it checks

The whole thing, against your intent.

  • The whole system, against what you set out to build.
  • Intent, structure, and behavior, checked as one.
  • A proof record of what holds, not a wall of green you have to trust.
  • Every project, checked the same way, with no senior as the bottleneck.
How it works

Three checks, then proof.

Subak reads your code against your intent and runs three passes, then signs off on whatever holds.

Pass 01

Static analysis

Reads the code for structural flaws before anything runs, catching the mistakes you'd miss on a first read.

Pass 02

Runtime tests

Runs the code to see what breaks in practice, not only what looks right on the page.

Pass 03

Senior review

A review pass that reads intent the way an experienced engineer would, catching the judgment calls tools miss.

Then: proof

Whatever passes gets a proof record showing exactly what was checked. Something you can attach to the delivery and stand behind.

Ship with proof of what passed.

AI made building easy. Subak helps you trust what ships.
