Rescue and stabilise
When something is on fire, we put it out first. We tackle the urgent bugs, outages and security holes so your system is dependable again from day one.
Legacy modernisation
Bring your ageing software back to life.
If a system your business depends on has become slow, fragile or unsupported, we can help. Codebased rescues, stabilises and re-platforms legacy software in the UK, so it is secure and dependable again, without the cost and risk of starting from scratch.
Trusted by established UK businesses
What it is
For businesses stuck on software they can no longer trust.
Legacy software modernisation is the work of taking a system that has aged badly and making it secure, stable and easy to change again. That might be an app built on outdated frameworks, a platform left unsupported when a developer moved on, or a tool that breaks every time you try to add something new.
It is for teams who rely on a system every day but have started to dread touching it, whose costs and downtime keep creeping up, or who feel locked in because nobody fully understands the code any more. We keep the value already built in, and remove the risk sitting around it.
What you get
A system that is safe to run and ready to grow.
Whether you need a quick rescue or a full re-platform, we shape the work around the outcome that matters most to your business.
Re-platform and upgrade
We move you off ageing frameworks and infrastructure onto a modern, supported foundation that is faster, cheaper to host and built to last.
Remove key-person risk
If one person held all the knowledge, we change that. We learn the codebase, document how it works and take ownership, so your business is no longer exposed.
Integrate with modern tools
We connect your system to the tools and services you use now, with clean APIs and reliable data flows that replace manual workarounds and copy-paste.
Tidy the code and tests
We refactor tangled code and add the automated tests that were missing, so future changes are quicker, safer and far less likely to break things.
Ongoing support
Once it is healthy, we keep it that way. Ongoing support and maintenance means your system stays secure and supported long after the project ends.
How we work
Low-risk, one careful step at a time.
We do not believe in risky big-bang rewrites. We modernise in small, incremental steps, so your system keeps running and you see progress the whole way through.
1
Assess
We review the codebase, infrastructure and risks, then give you a clear, honest picture of what is worth keeping and what needs to change.
2
Stabilise
We deal with the most urgent problems first, putting out the fires and locking down security so the system is dependable while we work.
3
Modernise
We upgrade and re-platform in small, tested increments, shipping improvements continuously instead of disappearing for a long, risky rebuild.
4
Support
We stay on to maintain, monitor and improve the system, so it keeps paying off and never slides back into legacy again.
Why Codebased
Senior people who have seen it before.
Inheriting someone else's software takes experience and a steady hand. That is exactly what we bring.
We inherit code calmly
Undocumented, unfamiliar codebases do not faze us. We are used to mapping how a system really works and taking ownership of it.
Senior, UK-based team
Your software is handled by senior engineers based in the UK, not handed off to juniors offshore. You always know who is doing the work.
Risk-first, not rewrite-first
We protect the business value already in your system and reduce risk incrementally, rather than betting everything on a single rebuild.
Honest about what is worth saving
Sometimes modernising is right, sometimes a fresh build is. We will tell you straight, even when it is not the bigger project for us.
Partners for the long run
We are not here to fix and vanish. We stick around to support your system and help it keep up with your business.
Focused on your business
We care about uptime, cost and the outcome for your team, not just the code. The goal is software you can rely on.
FAQ
Questions about modernising legacy software.
The things businesses ask us most before bringing an ageing system back to life.
Why modernise instead of replace?
A well-judged modernisation protects the years of business logic already baked into your software while cutting cost, risk and downtime. Modernised systems are cheaper to run, easier to support and often outperform a like-for-like rebuild.
How long does it take?
It depends on the size and state of the codebase, but we deliver in small, incremental stages rather than one long rebuild. We stabilise the most urgent risks first, then ship improvements continuously so disruption stays low.
Which technologies do you work with?
We assess your project to choose the best fit, and we work across a broad range of languages. For web applications we specialise in Laravel, React and Vue, and for mobile apps we work with React Native and Swift.
What if our original developer has gone?
That is one of the most common reasons clients come to us, and it is not a problem. We are used to picking up unfamiliar, undocumented codebases, mapping how they work and taking ownership so you are no longer dependent on one person.
Can you support it afterwards?
Yes. We offer ongoing support and maintenance so your system stays secure, supported and dependable long after the initial work. We are here for the long run, not a one-off project.
Is our software too old to modernise?
Almost certainly not. Whether your system is a few years or a decade old, there is nearly always a sensible path to make it secure, stable and fit for the future. We will tell you honestly what is worth keeping.
