How Much Does a Code Audit Cost?
Two options, both with senior engineers. Mentor is $29 a month for builders who want an expert on call. Partner starts at $1,000, a flat, fixed-scope fee for audits and for taking your app to launch and maintaining it with you.

What Determines the Cost of a Code Audit
Five factors drive the quote. We weigh them on the intro call so the number you get is realistic, not a placeholder.
Code Audit Cost by Type of Review
"Code audit" covers very different engagements. Compare what each one costs in effort, what it finds, and what it leaves out before you compare quotes.
| Review type | Relative cost | What it finds | What it misses |
|---|---|---|---|
| Automated scan | Lowest cost, minutes to run | Known vulnerable dependencies, leaked secrets, common code patterns. | Authorization, tenant isolation, payment logic, and anything specific to your business rules. |
| Focused code review | Fixed fee from $1,000, a few business days | The highest-risk flows in a small app: auth, data access, secrets, payments. | Deeper architecture and scalability questions outside the agreed scope. |
| Full code audit | Fixed fee scaled to codebase size | Security, reliability, architecture, and AI-specific risks across the whole product. | Runtime and infrastructure behaviour that only shows up against a live deployment. |
| Penetration test | Scoped by app surface and environments | Exploitable issues in the running app, APIs, and cloud configuration. | Code-level root causes unless paired with source review. |
| Technical due diligence | Scoped to deal timeline and depth | Security, architecture, scalability, dependency licensing, and team-practice risks for investors or acquirers. | Line-by-line remediation; it is an assessment, not a fix engagement. |
