Code Audit Pricing
Scanning a public repository on SystemAudit.dev is free, with no card and no signup. A full audit is priced by project size: $49 up to roughly 30,000 lines of code, $99 up to 75,000, and $199 up to 150,000. Larger codebases are quoted individually. You run the scan first and see your price before deciding.

How your price is decided
The scan measures your codebase, then the tier follows from its size. Nothing is estimated up front and nothing changes after you see the number.
| Project size | Lines of code | Price | Typical project |
|---|---|---|---|
| Small Project | up to 30K | $49 | Early-stage product, typically built by 1-2 developers |
| Medium Project | up to 75K | $99 | Growing system with multiple features, estimated 2-4 developers |
| Large Project | up to 150K | $199 | Complex system with multiple modules, 4+ developers over time |
| Enterprise System | 150K+ | Custom | Large-scale codebase — requires a dedicated analysis |
Built with Cursor, v0 or Bolt? Most AI-generated projects come in under 30,000 lines, which puts them at $49.
Auditing more than one repository
The size-based tiers cover a single repository. If you audit repeatedly — an agency vetting client code, an investor screening deals, a team tracking several services — the Unlimited subscription is $29 per month and applies full audit access to every repository you scan.
Ask about UnlimitedPricing questions
How much does a code audit cost on SystemAudit.dev?
A scan of a public repository is free. A full audit is priced by project size: $49 up to about 30,000 lines of code, $99 up to about 75,000, and $199 up to about 150,000. Codebases larger than that are quoted individually. You scan first and see your price before paying.
Why is the price based on lines of code?
Project size determines how much work an audit is: how many files are read, how many components are mapped, and how much analysis the report has to hold. Charging by size means a small AI-built project is not subsidising a large enterprise codebase. Your line count is measured during the scan, so the price is not an estimate.
What do I get without paying anything?
The free scan covers public repositories and returns the security and secrets scan, dependency analysis, and Handoff Readiness and Supply Chain Resilience grades. Every critical and high-severity finding shows its exact file, line and a redacted snippet without a signup — the location of an urgent problem is never gated.
Do I need a credit card to run the first scan?
No. The free scan on a public repository needs no card and no signup. You only pay if you choose a full audit after seeing what the scan found.
Is there a plan for auditing several repositories?
Yes. The Unlimited subscription is $29 per month and grants full audit access across every repository, rather than being scoped to one. It suits agencies, investors and teams running audits repeatedly instead of once.
Can SystemAudit.dev audit a private repository?
Yes, on the paid tiers. You connect your GitHub account securely and the analysis runs without your code being stored. The free tier covers public repositories only.
