AI has dramatically reduced the cost of producing software. Yet digital platforms remain expensive to maintain, difficult to evolve, and risky to scale.
That tension is changing how organisations think about delivery.
The future likely belongs to teams combining reusable foundations with strategic customisation rather than rebuilding everything from scratch.

Why fully bespoke delivery is losing its advantage
Bespoke delivery used to represent digital maturity. Building everything from scratch signalled ambition, differentiation, and technical capability.
In practice, many organisations ended up trading short-term flexibility for long-term fragility.
Fully bespoke platforms often create problems that compound over time:
- Custom business logic hidden inside undocumented code
- Upgrade paths blocked by tightly coupled architecture
- Repeated engineering effort solving the same problems
- Delivery slowdowns caused by platform complexity
- Internal teams becoming dependent on a shrinking pool of platform knowledge
The challenge emerges later, when the platform needs to evolve under commercial pressure.
A marketing team wants faster campaign delivery. A CTO needs cleaner upgrade paths. A delivery team is under pressure to scale across regions, brands, or services. Suddenly, the flexibility that once looked attractive becomes operational drag.
AI changes the economics of software production, but it does not remove the need for governance, maintainability, or architectural discipline.
If anything, faster code generation increases the importance of those things.
The real question organisations are starting to ask is not whether they can build custom software. But, whether rebuilding the same foundations repeatedly still makes sense.
The organisations moving fastest are building on proven foundations
The organisations moving fastest are combining reusable foundations with strategic customisation. They are becoming more selective about where bespoke engineering creates real value and where standardisation creates speed, stability, and scale.
Rebuilding common functionality creates drag
Many organisations still spend time and budget rebuilding things that already have mature solutions:
- Publishing workflows
- Design systems
- Accessibility patterns
- Authentication and permissions
- Search and navigation
- Content modelling foundations
Repeated customisation creates sprawling platforms with duplicated logic, inconsistent governance, and growing maintenance overhead.
Modular architecture can change the economics
Modular architecture can allow teams to evolve platforms in smaller, safer increments.
Components can be improved independently. Features can be reused across teams and services. New functionality becomes easier to introduce without destabilising the wider platform.
For technical teams, that creates:
- Cleaner upgrade paths
- Better testing and release processes
- Lower operational risk
- More predictable maintenance
For operational leaders, it creates:
- Faster delivery cycles
- Less duplicated engineering effort
- Clearer governance
- Better long-term scalability
Open platforms are accelerating the shift
Open-source ecosystems are pushing this model further.
Organisations are becoming more comfortable building on shared standards, reusable components, and collaborative delivery models instead of treating every platform as a completely unique system.
The Linux Foundation's State of Global Open Source 2025 makes the breadth of that shift clear: "Open source improves productivity (86%), reduces vendor lock-in (84%), lowers the cost of software ownership (84%), facilitates innovation (82%)."
The greater value comes from how well systems are assembled, governed, and evolved over time.
That changes the role of custom development.
Customisation still matters. Differentiation still matters. But bespoke engineering is becoming more targeted. Teams are focusing effort on the areas that genuinely create competitive advantage instead of rebuilding commodity infrastructure from scratch.
What LocalGov Drupal reveals about the future of delivery
LocalGov Drupal reflects a broader shift happening across digital delivery. Organisations are becoming more willing to build on shared, open foundations instead of treating every platform as a fully bespoke system.
That pattern is appearing across infrastructure, AI, search, and publishing platforms.
OpenSearch is emerging as an alternative to proprietary search tooling. LiteLLM helps organisations standardise how they interact with multiple AI models. Vertex AI provides reusable machine learning foundations instead of forcing teams to engineer every capability independently.
Drupal distributions follow the same direction.
Open Social, for example, gives organisations a mature foundation for community platforms while still allowing significant customisation around workflows, integrations, and user experience. Code Enigma used Open Social to help the Office for National Statistics build a large-scale community platform without starting from scratch.
Shared foundations create operational leverage
Reusable platforms allow organisations to stop rebuilding the same infrastructure repeatedly.
Common capabilities become shared foundations:
- Governance models
- Accessibility standards
- Authentication workflows
- Search infrastructure
- AI orchestration layers
- Publishing systems
- Integration patterns
Engineering effort can then focus on the parts of the platform that genuinely differentiate the organisation.
That changes delivery economics significantly.
Teams spend less time recreating commodity functionality and more time improving services, user experience, operational workflows, and business capabilities.
Open source is becoming a strategic decision
This shift also reflects growing concerns around control and resilience.
As digital platforms become operationally critical, organisations are paying closer attention to:
- Vendor dependency
- Licensing risk
- Data sovereignty
- Infrastructure portability
- Long-term maintainability
According to the Open Source Initiative's 2025 State of Open Source Report: "A remarkable 96% of organizations reported either increasing or maintaining their use of Open Source software in the past year. The number one reason? Cost efficiency."
Open ecosystems give organisations more control over how platforms evolve and where infrastructure and data are hosted.
That flexibility matters even more as AI capabilities become embedded into digital services. Many organisations want the freedom to adapt models, providers, and deployment approaches without rebuilding core systems every time the market changes.
LocalGov Drupal shows what collaborative delivery can look like
LocalGov Drupal demonstrates how shared delivery models can scale in practice.
Councils collaborate on common Drupal foundations covering publishing, accessibility, governance, and service delivery patterns. Individual organisations still tailor implementations around local operational needs, integrations, and services. LocalGov Drupal's own analysis puts it plainly: "LGD reduces the cost of a website rebuild by 30%–50%. Most LGD rebuilds cost £70k–£150k. Most proprietary rebuilds cost £80k–£250k or more."
The important point is the operating model behind the platform.
Shared foundations create:
- Faster implementation
- Stronger governance
- More consistent accessibility
- Lower maintenance overhead
- Broader operational resilience
The platform improves through collective contribution instead of isolated reinvention.
That model is becoming increasingly attractive as organisations look for scalable digital platforms that remain adaptable without becoming fragile.
The role of agencies is changing too
The economics of digital delivery are shifting underneath agencies as well. When software production becomes faster and cheaper, raw output becomes less valuable on its own. Clients place greater value on architecture, governance, operational thinking, and long-term sustainability.
That changes what organisations expect from delivery partners.
The strongest agencies are becoming:
- Technical advisors
- Platform architects
- Governance partners
- Integration specialists
- Contributors to shared ecosystems
They’re no longer just producers of bespoke code. The emphasis moves away from volume and towards judgement.
Clients want partners who can identify what should be custom, what should be reusable, and where complexity creates unnecessary operational risk.
That requires a different kind of engineering discipline.
Writing maintainable code matters more than writing large amounts of code. Understanding delivery trade-offs matters more than maximising billable development hours. Contributing to open ecosystems becomes strategically valuable because reusable improvements strengthen future delivery.
This is especially visible in open-source environments.
Agencies contributing to platforms like Drupal, OpenSearch, or collaborative distributions help shape the ecosystems their clients rely on. That creates stronger governance, better interoperability, and more resilient long-term platforms.
The delivery relationship becomes more transparent too.
Clients increasingly want visibility into architecture decisions, upgrade paths, infrastructure choices, and operational risk. Black-box delivery models become harder to justify when organisations are trying to reduce dependency and build more adaptable digital estates.
The agency model built around endless bespoke production starts to look increasingly fragile.
The model built around sustainable delivery, shared foundations, and strategic engineering looks far more aligned with where digital platforms are heading.
The future isn’t less custom, it’s more intentional
Customisation is not disappearing from digital delivery. Organisations still need platforms tailored to their operations, services, users, and internal workflows.
The shift is happening around the infrastructure beneath them. Shared foundations are becoming the starting point, with bespoke engineering focused on the areas that create meaningful differentiation.
Rebuilding common infrastructure repeatedly creates maintenance overhead, upgrade complexity, governance drift, and operational risk.
Reusable foundations are becoming the starting point.
Open ecosystems, modular architecture, collaborative delivery models, and composable platforms allow organisations to move faster without creating fragile systems that become harder to evolve each year.
That shift changes how digital teams make decisions. The questions that need to be asked are:
- What genuinely needs to be bespoke?
- What should be shared?
- What creates differentiation?
- What simply recreates complexity?
The organisations that scale most effectively over the next decade may not be the ones building the most software.
They will likely be the ones making smarter decisions about what should already exist.
For teams managing complex digital estates, that means thinking beyond short-term delivery. Platforms need to remain maintainable, adaptable, and operationally sustainable long after launch.
That’s where strong architecture, open collaboration, and sustainable delivery practices start to matter far more than the amount of code being produced.
