The App Maintenance and Support gaps we get called in for
Most people don't come to us because everything's running smoothly. They come because something specific is starting to cost them time, money, or trust with users.
We can take over an existing application cold, reviewing the codebase, the repositories, and whatever documentation exists, even if it's thin. Missing documentation isn't a dealbreaker; it just means the technical health check takes a bit longer.
Repeated crashes, failed transactions, and integration errors are usually a symptom, not the problem itself. We dig into the root cause instead of patching the same fault every few weeks, then prioritise fixes by the impact they're actually having on users.
Outdated frameworks and unsupported dependencies pile up quietly until every change takes longer than it should. We map out where the technical debt sits and build a realistic plan to work through it, rather than a rewrite nobody's budgeted for.
A support agreement doesn't have to stop at keeping the lights on. Planned development hours can go toward new features, UX changes, and integrations, so the application keeps moving forward instead of standing still.
Application Support Services built for how modern businesses run
Application maintenance services at chilliapple cover the full technical life of the application, not just the bits that break.
Our featured work
Delivering measurable impact across industries, we help both established enterprises and ambitious startups achieve sustainable success.
Which Application Support model fits your business?
A customer-facing mobile app and an internal admin tool don't carry the same risk, so they shouldn't get the same support arrangement. We look at the software, the user base, the integrations, and the business impact before recommending a model, and we scope it properly before agreeing on a price, rather than quoting blind.
How does AI Fit into Modern Application Maintenance?
Used well, AI takes the tedious part of the job off a developer's plate. Used badly, it becomes an excuse to skip the judgment that actually keeps applications safe. We're only interested in the first version.
-
Log analysis- AI checks thousands of log entries and picks out what's actually unusual, instead of a developer scrolling through them one by one.
-
Incident grouping- If several tickets all trace back to the same cause, they get fixed together, not one at a time.
-
Faster triage- Developers get the useful context straight away, so they're not spending the first half hour just figuring out what's going on.
-
Early risk detection- Unusual behaviour gets flagged while it's still small, before it turns into an outage.
-
Performance insights- AI helps show where the application is running slow, unstable, or using more resources than it needs to.
-
Proactive maintenance- Patterns in the application's own data help decide what to fix next, based on what's actually happening, not just what's been reported loudest.
AI gives us a clearer picture of what's happening inside your application. That's what lets us fix things before they become problems, rather than after.

Why do UK Businesses choose chilliapple for application support?
An established UK development partner, chilliapple has supported organisations from its UK offices since 2008, with a team of around 70 people covering web, mobile and software specialisms.
Support backed by real development capability
When a problem needs more than a configuration tweak, our wider development team can work across application code, UX, integrations and long-term product development, not just ticket triage.
One team across web and mobile
Customer-facing and internal applications, browsers, iOS, Android, and cross-platform frameworks all sit under the same roof, including the services and integrations behind them.
Clear communication, not black-box support
An account-management and ticketing process keeps requests visible and completed work recorded, with reporting that flags emerging risks rather than burying them.
Application maintenance and support that can evolve
Your agreement gets reviewed as the application, the user base, and your priorities change; it isn't locked to whatever made sense on day one.
Our Five-Step approach to Application Maintenance and Support
We don't jump straight into fixing things. Every application gets the same structured path, from understanding what it does to reporting on what's changed, so nothing gets missed along the way.
We learn how the application supports your users and your business.
We review the technology, access, dependencies, and immediate risks.
We separate urgent stabilisation work from routine maintenance and longer-term improvements.
Requests are logged, assessed, resolved, and tested through an agreed workflow.
Reporting and technical insight shape the next round of maintenance and development priorities.
Which technologies and platforms do you support?
We don't tie ourselves to one stack, because your application shouldn't have to be rebuilt just to get proper support. Here's where our current expertise sits, organised by application layer.
-
Mobile: iOS, Android, Swift, Kotlin, Flutter, React Native
-
Front end: JavaScript and the modern frameworks built on top of it
-
Back end: PHP, Laravel, .NET, Node.js
-
Data and integrations: APIs, databases, payment services, CRM and third-party platforms

What our clients say
Chilliapple 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!

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
Do you work on applications you didn't build?
Yes, and it's most of what this page is about. We start with a structured takeover and technical assessment covering the codebase, environments, dependencies, and known issues, then recommend any stabilisation work before ongoing support begins.
Do you support both web and mobile applications?
We do. Browser-based business applications and customer portals sit alongside native iOS and Android apps and cross-platform mobile builds, plus the APIs and integrations connecting them.
Can you add new features while maintaining the application?
Yes, support doesn't have to mean standstill. Many agreements include planned development capacity for new features, UX improvements, accessibility work, and integrations alongside the maintenance itself.
How much do app maintenance and support services cost?
Application maintenance and support typically cost 15–25% of the original build cost per year, or roughly £1,500–£8,000+ per month for custom software, with ad‑hoc rates around £60–£150 per hour depending on SLA and complexity.
How long does it take to take over an existing application?
That comes down to access and documentation more than anything else. Once we have the repositories, hosting details, and any relevant credentials, we can run the technical health check and put together a realistic transition plan.
What are the advantages of using a dedicated application support services?
It turns support from a scattered inbox into something manageable. Centralised tickets, SLA visibility, an audit trail, and enough data over time to plan maintenance instead of just reacting.
