An audit is a quick way to see what the tool left behind before real customers find it: security gaps, exposed keys, and data that isn’t locked down. When there’s work to do, our [vibe coding cleanup](https://velocitylabs.io/vibe-coding-cleanup/) takes it from there. ## Questions about code audits #How much does a code audit cost? Each level is a fixed fee: $1,000 for Essentials, $1,500 for Standard, and $2,500 for Comprehensive. [Compare what each one covers](https://velocitylabs.io/code-audit/#pricing). #How long does a code audit take? Typically less than a week, depending on the size of your app and the level you choose. #What's in the report? A plain-language summary up front, with a grade for each of the eight areas and the risks that matter. Behind it are the specific findings with their fixes, and a prioritized plan with effort estimates, so owners and developers can both act on it. #Do you need access to our servers? No. We review a copy of your code in an isolated, disposable environment that’s deleted right after, and we never connect to your production servers, databases, or accounts. #Can you audit an app built with Lovable, Replit, or Base44? Yes. AI-built apps get the same review, and it’s often the fastest way to find the security gaps they ship with. If the audit turns up work, [vibe coding cleanup](https://velocitylabs.io/vibe-coding-cleanup/) is how we fix it. #Do we need a technical due diligence review before buying a software business? If the software is a big part of what you’re buying, it’s worth it.
