CODE AUDIT Part of Software Product Development

A code audit that ends with someone accountable for the app.

You built it with Lovable, Replit, Bolt, or Cursor, or you inherited it from a team that left. It works, and you do not fully trust it. One senior engineer audits the codebase in one to two weeks for a fixed fee of $4,000 to $12,000: security, architecture, tests, deployment, and monitoring. You get a prioritized fix list and a quote to certify and take the app over.

WHAT YOU GET

Six things a code audit has to answer before anyone takes the app over.

The audit is a written read on the codebase you actually have, not a rewrite pitch. It is scoped so the fix list is actionable by whoever does the work next, us or anyone else.

Security review

Authentication and authorization paths, secrets and keys in the repository or the client, injection and input handling, dependency vulnerabilities, and the data your users would not want exposed. Findings are rated by severity and by how easy they are to exploit.

Architecture and data model read

How the application is put together, where the AI tool or the previous team took shortcuts, which parts will break under real load or the next feature, and what the schema does to your data over time.

Test coverage and code quality

What is tested, what is not, and which untested paths carry money or user data. A read on duplication, dead code, and the patterns that make the codebase slow to change safely.

Operations readiness

How the app deploys, whether a bad release can be rolled back, what is logged and monitored, how backups run, and what happens when a third-party API fails at 2 a.m.

Prioritized fix list

Every finding in one ranked list: fix before the next customer, fix this quarter, and leave alone. Each item sized so you can hand it to any engineer, including ours.

Takeover quote

A written quote for a senior team to fix the critical items, certify the app, and take over maintenance on a monthly retainer with on-call and incident response. Optional. The audit stands on its own if you take it elsewhere.

HOW IT WORKS

From first call to fix list in one to two weeks.

Four steps, one senior engineer end to end. You keep building while the audit runs.

  1. 01

    Call, 30 minutes

    You walk us through the app, how it was built, who uses it, and what worries you. We confirm the fee inside the published range based on the size of the codebase and the number of services.

  2. 02

    Read-only access and scope

    You grant read access to the repository, the hosting account, and the database schema. We agree what is in scope and what stays out, in writing, before the clock starts.

  3. 03

    The audit, one to two weeks

    A senior engineer reads the code, runs the security and dependency checks, traces the risky paths by hand, and tests the deploy and rollback story. Questions come to you in one thread, not a stream of meetings.

  4. 04

    Readout, fix list, and quote

    A written report and a live readout, in plain language. You leave with the ranked fix list, a certification checklist, and a quote for us to fix the critical items and take over the app, if you want that.

PRICING

$4,000 to $12,000, fixed before we start.

We publish the range because you should not need a sales call to learn what a code audit costs. The exact fee is set on the first call from the size of the codebase and is fixed at signing. No hourly meter.

WHAT MOVES THE FEE INSIDE THE RANGE

  • Codebase size: a single web app of a few thousand lines sits low in the range; a multi-service platform sits high.
  • Number of integrations: payment providers, auth services, AI APIs, and the data each one moves.
  • Data sensitivity: health, financial, or personal data raises the depth of the security review and the compliance questions we answer.

WHAT THE FEE BUYS, AND WHAT COMES AFTER

The audit is a standalone product: the report and the fix list are yours to give to any engineer. If you want us to do the fixing, the quote covers certifying the app and taking it over on a monthly support retainer with on-call, patching, and incident response. Most audits close with a takeover conversation; none require one.

IS THIS YOU

When a code audit is the right first step.

The four situations that bring most people to this page.

  • Your AI-built app has paying users

    Lovable, Replit, Bolt, or Cursor got you to launch, and now real customers and real data are on it. You need to know what is under the hood before the next hundred sign up.

  • An investor or a customer asked about security

    Due diligence, a security questionnaire, or an enterprise prospect wants a posture you can describe. The audit gives you a written answer and the list of what to fix first.

  • The team that built it is gone

    The agency wrapped up, the freelancer stopped answering, or the co-founder left. You own a codebase nobody on your side has read, and you need someone accountable for it.

  • You need a senior team to take it over

    You do not want a report. You want the critical items fixed and someone on call when it breaks. The audit is how we take over an app without guessing.

WHAT THIS IS NOT

Four things a code audit is often confused with.

Not a penetration test

A pen test attacks the running system from outside. The audit reads the code, the configuration, and the deploy pipeline from inside, which is where most problems in AI-built and inherited apps live. If you need a pen test as well, we say so in the report.

Not a free review with a sales agenda

Free audits exist to sell a rewrite. This one is paid, fixed-fee, and useful on its own. Declining the takeover quote is a normal outcome, not a failed sale.

Not a rewrite pitch

Most AI-built apps do not need to be rebuilt. They need the risky parts fixed and someone watching them. The fix list separates what to fix, what to harden, and what to leave alone.

Not a verdict on how you built it

Building with AI tools was the right call for getting to market. The audit is about what the app needs now that it is in production, not about how it got there.

AFTER THE AUDIT

Need a technical owner, not only a fix list?

Some founders leave the readout with a clear list and a team to hand it to. Others realize the app has no technical owner at all. For them, a named Leanware tech lead can step in part-time as a fractional CTO.

Fractional CTO

A named senior tech lead from our team, one or three days a week, on a monthly retainer. Owns the roadmap, the architecture decisions, and the vendors, and answers to you.

FREQUENTLY ASKED

Questions founders ask before a code audit.

The questions we hear from people who built with AI tools or inherited a codebase, and are deciding what to do next.

  • How much does a code audit cost?

    $4,000 to $12,000, fixed at signing. The exact fee depends on the size of the codebase, the number of services and integrations, and how sensitive the data is. One senior engineer does the work in one to two weeks. A single AI-built web app usually lands in the lower half of the range.

  • How long does a code audit take?

    One to two weeks from access to readout. A single web application with a handful of integrations takes about a week; a multi-service platform or a codebase with health or financial data takes two.

  • What does the audit include?

    Six things: a security review (auth, secrets, injection, dependencies), an architecture and data-model read, test coverage and code quality, operations readiness (deploy, rollback, monitoring, backups), a prioritized fix list, and a quote to certify and take over the app. The report is written in plain language with a technical appendix.

  • Is this a web application security audit or a penetration test?

    It includes a security review of the code and configuration, which is where most vulnerabilities in AI-built apps live: exposed keys, weak authorization, unvalidated input, outdated dependencies. It is not a penetration test of the running system. If your compliance need calls for one, the report says so and we can point you to a testing partner.

  • Can you take over an app built with Lovable, Replit, Bolt, or Cursor?

    Yes, that is the most common path. The audit tells us and you what the app needs. The takeover quote covers fixing the critical items, certifying the app against the checklist, and maintaining it on a monthly retainer with on-call and incident response. You keep ownership of the code and the accounts throughout.

  • What happens after the audit?

    You decide. Hand the fix list to your own engineers, take it to another vendor, or accept our quote to fix and take over. The report does not expire and does not depend on hiring us.

  • Do I have to stop building during the audit?

    No. We work from read-only access to a snapshot of the repository and the hosting configuration. You keep shipping. If something changes materially during the audit, we note it in the report.

  • Can the audit support technical due diligence for a raise or an acquisition?

    Yes. The report is written so an investor or an acquirer can read the summary and their technical reviewer can read the appendix. Tell us on the first call if that is the purpose, and we shape the readout for it.
