Independent audit · works on top of any hire

An independent audit of the AI-built app you were handed.

Whether you hired on Upwork, Fiverr, or directly, a 5-star delivery doesn't tell you if the code is secure, maintainable, or does what was promised. We do — with evidence you can inspect.

A 5-star delivery can still break in production.

It demoed perfectly. Whether it survives real traffic, real data, and real users is a different question.

5-dimension audit: problem fidelity, live behavior, code quality, security, integrity.

🛡️ ProofStack is an independent verifier— we're not the developer who built it, and we take no cut of your hire. We just tell you the truth about the code you received.
