A second opinion on your own team’s code
You suspect something is wrong and cannot prove it. Your team tells us where to look first, and your engineers can check every finding.
Codebase audits
Find out what shape the software your business runs on is really in. Senior engineers read the code and tell you, in plain English, whether to keep it, fix it or rebuild it.
No fee, and it can come back saying your codebase is in reasonable shape.
A source code audit is an outside check of the code behind your business software. It tells you what is broken, what is risky, and what to do about it. At The Gnar Company, senior engineers in the U.S. read the code, with help from an AI tool Gnar built, and explain what they find.

The audit
Security holes, code that breaks when anyone changes it, and parts likely to slow down as you grow.
Small fixes your team can make now, kept separate from the big decisions.
Where nobody wrote down how it works, we explain what the main parts do.
Your options, and the next steps for each one.
Two ways in
What you need to know depends on who wrote the code.
You suspect something is wrong and cannot prove it. Your team tells us where to look first, and your engineers can check every finding.
The company that built it left, or the people who built it moved on. We explain what the main parts of the code do, so the next team knows what it is working with.
Proof
Audit said: rebuild on newer technology

Audit said: keep the system, build a new app

Audits, then upkeep on an older app

How it works
We read the code before anyone talks about a rebuild.
We sign a non-disclosure agreement. Then you, or whoever holds the code, give us access. That is all it takes to start.
Senior engineers read the code, with help from our AI tool, and work out what the main parts do.
A written audit, worst problems first, with what to do about each one. We walk your leaders and your engineers through it.
Common questions
Still have questions?
Yes. The Gnar Company’s code audit is free. Gnar signs a non-disclosure agreement before it sees any code. Then senior engineers read it and send back what they found, worst problems first. You decide what to do next, with Gnar or without.
Because The Gnar Company reads existing code before it takes on any project. It does not charge for that. You get the findings either way, whether or not you hire Gnar. The audit also tells Gnar whether the code is something it can take on.
Two things: a signed non-disclosure agreement and access to the code. The Gnar Company signs the agreement first. After that, anyone who holds the code, such as a contractor or a past vendor, can share access. Your team can also tell Gnar where to look first.
A Gnar code audit checks the code, how it is put together, and how it connects to your other systems. Senior engineers read it, and Gnar’s own AI tool checks it too. They look for security holes, missing tests and technical debt (old shortcuts that make every change harder). Gnar’s audit of the AARP Foundation’s property tax tools found security holes and missing tests.
Senior engineers at The Gnar Company, all based in the U.S. They read the code, helped by an AI tool Gnar built. Afterward, they take your leaders and engineers through the findings, so your own team can check each one.
The Gnar Company can, for free. Its code audit ranks what it finds in your code, worst first. That includes security holes and technical debt (shortcuts that slow down every future change). You also get the quick fixes, listed apart from the bigger choices.
Yes. The Gnar Company audits code that another vendor built. It reads that code before agreeing to take any of it on. The AARP Foundation work started that way. Gnar checked tools a previous firm had built and took them over. Then it made them stable and moved them to a new platform.
Then it says what to rebuild and what to keep. Take the AARP Foundation. The Gnar Company’s audit showed that a new platform would cost less than building on the old code. It also carried less risk. For First Line Technology, Gnar’s review said to keep the existing system. Gnar built a new app on top of it, which cost less than fixing the old app.
No. The Gnar Company’s code audit does not commit you to anything. If your own engineers can make the fixes, the audit says so. If you want help with the rest, Gnar can do that too. It can move the software to a new platform, keep it running, or rewrite the parts that need it.
Start by understanding what the code does. In a Gnar code audit, senior engineers read the code. They work out the main business rules nobody wrote down, like how an order gets priced. If a rebuild follows, The Gnar Company turns the old code into a written plan for the new software. Then it builds from that plan. It does not copy the old code line by line.
Ask three questions. Does the code have tests? Is it organized? Can anyone explain what it does? A Gnar code audit answers all three and ranks the gaps it finds. For AI across the rest of the business, The Gnar Company runs a separate, free AI Readiness Assessment.
The Gnar Company audits code in the stacks its engineers use every day. That means Ruby on Rails, React, Node.js and React Native, on AWS, Google Cloud and Azure. They have also read and rebuilt older PHP and Python software. If you are not sure what your system is written in, ask anyway. Gnar can tell once it has access to the code.
