Independent Code Review & Software Audit

Get actionable insights into your code quality, architecture and bottlenecks from the architects who helped scale Fitbit, Tonal, Monster Energy and more.

What is a Code Review and Software Audit?

A code review and software audit is an independent assessment of an existing product's technical condition. Mercury Development evaluates code quality, architecture, scalability, maintainability, dependencies, performance risks, security concerns, testing coverage and documentation to surface issues that may affect future development.

Code review · What we cover

What We Review

We examine the areas of your product that most affect its stability, security and cost of change. Each area below is assessed in depth, then summarized in a structured report with prioritized findings and practical recommendations.

Code Review
Pricing and Timeline

The duration of a code review depends on codebase size, number of repositories, technology stack, documentation quality and review depth. A limited review of a small product is faster, while larger systems require a deeper assessment. After an initial call and a short intake review, we define the scope, timeline and expected deliverables.

Quick Review for 1-2 days
$1,000

High-level overview of general architecture and dependencies. A smaller report, ideal for an easy, general validation check of the codebase.

Smaller-Scale Review for 1 week
$2,000

A deeper review of an application or platform, ideal for growing products. Includes recommendations for future expansion.

Full-Scale Review for 2 weeks
$4,000

Who Benefits From a Code Review?

When do You Need a Code Review?

A code review helps when you already have a product but need an objective view of its quality, risks and readiness for further development, scaling or investment.

  • You are about to invest in a new feature roadmap or major release.

  • Adding features is getting slower, buggier or more expensive.

  • You have performance, scalability, reliability or security concerns.

  • Preparing for growth, modernization, or due diligence.

What You Get

At the end of the review you receive a structured report that explains the current state of the codebase, highlights key risks and provides prioritized recommendations for improvement. The report can be used internally, shared with stakeholders, or as a starting point for project takeover, refactoring, modernization or continued development.

Detailed report

A comprehensive report document explaining the current state of the codebase, the key risks and prioritized recommendations.

Proposal presentation

A proposal presentation that summarizes the key findings and the recommended next steps in a format you can share with stakeholders.

We’ve actually brought Mercury in across three totally different companies. First it was an app for car sales, then later they stepped in to fix a fire safety app that needed help, and now they’re building stuff for a valve manufacturer. Kinda shows they can jump into all sorts of industries and just get the work done.

Mercury is very organised and there are no hidden surprises. They first scoped the project in detail, questioning the specification supplied as necessary. They also focussed on the success testing right from the start. I was also guided through the process so it was very straight-forward.

Mercury was awesome, they were reasonably priced, and took ownership over the project from the get-go. The code is clean, the app is polished, and they made multiple revisions very easy and at no additional charge. I would highly recommend working with them again, especially if you need an Apple TV app built with an API to your YouTube channel.
