Application maintenance and support services for UK businesses with live products, ageing codebases or a growing backlog of improvements: bug fixes, updates, monitoring and planned releases.
UK-registered company. International engineering team.

Application maintenance for UK businesses.
Software that is live needs looking after: dependency updates, security patches, small fixes, performance regressions, the feature the sales team promised. Krapton provides application maintenance for UK businesses whose original developers have moved on, whose in-house team is stretched, or who simply want a dependable partner for the product they depend on.
We take over web applications, mobile apps, APIs and internal systems in a structured way: a codebase and infrastructure assessment first, a prioritised backlog, then reserved monthly capacity with agreed support hours and escalation routes. No surprises, and a product that keeps improving.

Why UK businesses
choose Krapton for application maintenance.
A structured takeover
Repository, deployment and documentation review, known-issue triage and a risk register before any change is made to a live system.
Security and dependency hygiene
Regular framework and library updates, vulnerability monitoring and patching, with releases tested before they reach production.
Monitoring and faster fixes
Error tracking, uptime and performance monitoring, so problems are found before customers report them and fixed with evidence.
Improvements, not just repairs
Reserved capacity that also delivers the small features and performance gains that keep the product competitive.

Application maintenance: questions UK buyers ask.
Can you maintain software that another company built?
Yes. Most maintenance engagements start that way. We begin with a codebase, infrastructure and documentation assessment, agree a handover plan and only then make changes to the live product.
What does an application maintenance retainer include?
Reserved monthly capacity used for bug fixes, security and dependency updates, performance work, monitoring and small improvements, with agreed support hours and an escalation route. The mix is set with you and reviewed regularly.
Do you offer 24/7 support or an SLA?
Support hours, response expectations and any service levels are agreed for your specific engagement rather than promised in advance. Tell us what your operation needs and we will propose an arrangement that fits.
Which technologies do you support?
Modern JavaScript and TypeScript stacks (React, Next.js, Node.js), PHP and Laravel, Python, .NET, React Native and Flutter mobile apps, and the major cloud platforms. If your stack is unusual, ask; we will tell you honestly whether we are the right fit.
How do you handle UK data protection during maintenance?
Access is limited to named engineers, granted through your own systems and logged. Production data is not copied to local machines, and any data processing agreement your organisation requires is put in place before work starts.
