Code review that starts with how your business works
A tool can tell you a line of code looks wrong. It can't tell you whether that line matters to your customers, your orders, or your reports. We start by understanding what your software does for your business, then review the code with that in mind. A review helps when:
Your relationship with your previous developer or agency has come to an end, and nobody internally fully understands the code.
New features take longer than they should, and fixes break other things.
You're about to launch something big.
Your team writes a lot of code with AI assistants.
Your software has slowed down as more people use it.
You're thinking about a rebuild but aren't sure it's needed.
Benefits of code review
Code reviews matter because they find problems while they're still small and easy to fix. Your software might work well today, but security gaps, messy code, and slow queries can build up quietly over time. A review gives you an honest picture of your code, so you can plan your next step based on facts.
Catch Security Problems Early - A review finds weak points, like exposed passwords or unsafe settings, before an attacker does. Fixing them early protects your customers' data and your reputation.
Support Your Compliance Work - If your software handles personal data or card payments, a review shows where your code could put that data at risk, so you can fix it before an audit.
Fewer Bugs After Release - Problems you fix after a review never reach your customers. Your team spends less time fixing live issues and more time building new features.
Lower Costs Over Time - A problem found before launch usually takes less work to fix than one found after it has affected live data or customers. A review helps you deal with issues before they grow.
Our Code Review Services
Every review is shaped around your software, from one feature before launch to a whole system you've taken over. AI tools speed up the first pass, and our developers add what the tools missed. You get a report that ranks each issue by risk and explains the fix.
Ready to find out what's in your code?
Tell us about your software and what's worrying you. We'll agree on the scope in a discovery session, then give you a fixed price for the review.

Common problems a code review uncovers
Some of the most damaging problems don't show up when you click around your software. They only show up in the code, or when someone tries to misuse it. These are some of the issues our reviews look for.
If your software passes what people type into forms, search boxes, or web addresses straight into a database query, an attacker can type in commands instead of normal text. That can let them read, change, or delete your data. We check where your software takes input from users.
Some sites let users post text, such as reviews or comments. If your software doesn't handle that text safely before showing it, an attacker can hide a script in it. The script then runs in other visitors' browsers and can take over their accounts.
Problems with how your software handles passwords and sessions can let someone pretend to be another user. A session is how your software remembers you're logged in as you move between pages. We check how passwords are stored and how long sessions stay open.
These are mistakes in the rules your software follows. For example, a customer might apply a discount code twice or skip the payment step. Scanning tools often miss these because they don't know how your business is meant to work. Our developers check for them.
AI code review that takes the pressure off your developers
Your developers are busy building. Checking every change properly takes time they rarely have, especially now that AI assistants help them write more code than before. Our AI code review gives them a second pair of eyes, with one of our developers making the final call.
AI tools scan each change and flag likely problems in minutes.
Our developers decide which flags are real problems.
Your team gets clear notes on what to change before code goes live.
Regular reviews can run alongside your team's own work.
Our code review methodology
Every review follows the same clear steps, so you always know what's happening and what comes next. We focus our time on the parts of your software that matter most to your business. You stay involved from the first call to the final walkthrough.
Tell us which parts of the code to focus on, how your system fits together, and what's worrying you. Share any design documents you have. We mark the highest-risk areas, like logins and payments, then give you a fixed price.
You give us access only to the code the review needs. Before we start, we agree with you whether AI tools can be used on your code and how.
Where you've agreed, tools such as Claude Code, Codex, or GitHub Copilot scan the code first. Our developers then read the high-risk parts closely, looking for problems the tools miss, such as gaps in your business rules.
We check that each finding is real and rank it by the harm it could cause your business. If we find something urgent, we tell you straight away rather than waiting for the report.
You get a written report that lists each issue, where it sits in the code and why it matters, with clear steps your developers can follow to fix it.
We go through the findings with your team and answer their questions. Once the fixes are in, we can check them again to confirm each issue is closed.
Why choose chilliapple?
A code review company is only worth paying for if you can trust the findings and your team knows what to do with them. Our reviewers are developers who build and maintain software for UK businesses every day. They use AI tools to work faster and explain what each finding means for your business.
We Check the Whole System - Many review tools only look at the lines that changed. Our developers also check how each change affects the rest of your software, so knock-on problems don't slip through.
We Start With the Riskiest Parts - Before reading any code, we map where your software handles logins, payments, and customer data. Those parts get the closest look, so the review time goes where a problem would hurt your business most.
Help With the Fixes If You Need It - Once you have the report, your own team can work through it, or we can scope the fixes as a separate piece of work. Some clients then move on to our software support and maintenance service.
Honest About What a Review Can Cover - No code review can promise to find every problem. We tell you plainly what's in scope, and if your software needs a separate security test as well, we'll say so.
What our clients say
We're just about to hit our 1 Year anniversary working with Chilli Apple and it seemed like a apt time to give feedback on our experience so far!
After years of struggling to get straight answers, waiting days for replies & solutions it was an absolute breath of fresh air to work with the Chilli-Apple team, specifically Jade & Lauren! [+]
Pentland Wholesale
Chilliapple were fantastic with our project. With me not being the most technically minded, they managed to simplify everything and fully understand what we wanted whilst explaining the process and accurate timelines. Highly recommend.
Steven GentChilliapple accelerates company success Chilliapple have been the fuel in our companies engine for the past year by helping us to develop the signature product and get it launched. Avatar is ready for use thanks to Chilliapples tremendous technical delivery design and delivery process.
Jeff Nogosek Avatar
Their communication skills and ability to complete the project within budget and timescale were impressive.
After the launch of the website, the client received feedback from customers concerning a better UX, and Chilliapple Ltd. was able to update easier than before. They communicated through Campfire and had weekly updates through Zoom meetings. Overall, the team provided a good value for the budget.
Luisa Coates Thermapen
Good Knowledge of Magento: Chilliapple was recommended to us for their Magento knowledge which has proved to be excellent. We worked with Bowo and Vipin to migrate and upgrade our existing Magento shops to a new UK Fast server with additional features and plug ins installed resulting in a faster admin than we previously had. I would recommend Chilliapple for Magento especially multiple shops.
Steve Long Merlin Workwear
Great work with the team at Chilliapple. They undertook our website maintenance from a previous developer and they have managed to accommodate many of our initial needs, including an upgrade to Magento 2.4.
Since then, we have overcome many more requests to improve website and shopping functionality and while I personally will not be overseeing their work anymore, I trust though that Versapak are in safe hands and that they can meet any new challenge that may arise.
Jeremy Graham Versapak
I've worked with many web agencies in the past and ChilliApple certainly shine above the rest. Our account manager Bowo has been extremely attentive and pro-active, without whom we would not have been able to deploy our Magento 2 migration by the end of 2020.
We're very pleased at the hard work and patience that Bowo and the development team have put into this project, especially as we were working long hours towards the end. I look forward to continued work with ChilliApple in 2021!
Laura Lam Phoenix Medical
Our website is built in Prestashop, and finding credible developers to maintain and progress the site was very difficult once we had made the decision to move on from our current developer.
Chilli Apple initially upgraded and re-themed our site to a very high standard with excellent communication throughout. We went live with the update (which was quite a major undertaking as it had not been done for some time and a lot had changed) right at the beginning of the COVID fiasco. [+]

Frequently Asked Questions
FAQ listings
How much do professional code review services cost?
Professional code reviews usually cost between £1,250 and £2,500 for each day of a reviewer’s time. Fixed-price reviews often start at around £3,500, and larger reviews can cost £7,000 to £20,000 or more. At chilliapple, we agree the scope with you in a discovery session first, then give you a fixed price.
How long do professional code review services typically take?
A review of one feature or area can take a few days. A standard review of a whole application usually takes 1 to 3 weeks, and larger or more complex systems take longer.
Can code reviews fit into an agile development process?
Yes. Agile teams build software in short cycles, often called sprints, and release changes often. We can review each set of changes as your team goes, or check the code before a bigger release. That way, reviews keep pace with your team instead of holding it up.
How do I choose a reliable code review agency?
Ask who will actually read your code, and whether they build software themselves. Check whether a person reviews what AI tools flag, what the report includes, and whether they can help with fixes. A good code review agency will also explain how it handles your code and tell you plainly what the review can’t cover.
Can you review code written with Codex?
Yes. Codex is OpenAI’s AI coding tool. Our Codex code review checks that the code it wrote does what your team intended and fits the rest of your system. Your developers get clear notes on what to change before the code goes live.
