Subak
Verify your client work

Prove your code works before your client opens it.

Subak checks the code you're about to deliver against the brief, then hands you a record to send with it. Catch the breakage before your client does, and keep your rating clean.

The risk

You shipped it fast. Do you know it works?

AI writes the code in minutes. It also writes bugs that look fine until your client hits them. Then you eat the revision, the dispute, or the refund, and your rating takes the hit for a mistake the model made.

The code you hand over can carry problems neither you nor your client can see until it's too late.

“Looks done” isn't the same as “holds up.”

AI writes the happy path in minutes. The bug your client hits on day three was never in the demo, and the revision lands on you.

What it checks

What Subak checks before you deliver

Subak reads the brief and the code, then checks one against the other. Anything that drifts from the brief shows up while you can still fix it quietly.

Pass 01

Static analysis

Catches the structural problems in the code before anything runs.

Pass 02

Runtime tests

Runs the code to see what happens when it runs, not only what looks right.

Pass 03

Senior review

Reads the work the way a senior developer would, catching what the client would notice.

What you hand over

A record that says the work was checked.

When the work holds up, Subak gives you a proof record of what it checked and found. Attach it to the delivery, and the client sees the work was tested against their requirements. "Does this even work?" becomes a question you've already answered.

Why it pays

What proof does for a freelancer

  • Revision rounds shrink, because the breakage surfaces before your client finds it.
  • Disputes and refund requests drop when the delivery arrives with a record attached.
  • Your rating stays protected, which on these platforms is the whole game.
  • "Checked and documented" reads like premium work, so you can charge like it.

Your rating is the whole game. Subak protects it.

Every delivery arrives with a record attached, so disputes and refund requests drop and reviews stay clean. Fewer revision rounds, a rating you get to keep, and documented work that lets you charge like the professional you already are.

Common questions

Verifying client work, answered

Delivering AI-built work to clients? Here’s what freelancers ask before they hand it over.

Ask a question
01 How do I prove AI-generated code works to a client?

You check it against their brief and hand over the record. Subak does the checking and produces the record, so the client sees the work was tested rather than taking your word for it.

02 Will this cut down on revisions?

It's built to. Subak surfaces the problems that usually come back as revision requests, so you can fix them before the client ever sees them.

03 Do I need to be a strong coder to use it?

No. Subak explains what it found in plain language, with fixes you can hand straight to your AI tool.
