Vibe Coding Services

Vibe coding is AI-assisted development where a senior practitioner works collaboratively with AI tools to build production-quality software. It’s not pasting code into ChatGPT — it’s a sustained development methodology involving architecture decisions, hundreds of iteration cycles, production testing, and the strategic oversight that only comes from experience.

We’ve been doing this since before it had a name. The interactive ROI calculators we built for Coviant Software generated over 200 enterprise leads and contributed to more than £2M in sales pipeline. The WordPress plugins we developed for roofingcladdingbuilding.com extended a compromised platform into a stable, high-performing site. The theme powering seostrategy.co.uk — 13,631 lines of production code managing 50+ pages — was built entirely through AI-assisted development in six weeks.

If you need something built that goes beyond a standard website — a calculator, an interactive tool, a WordPress plugin, a conversion-focused asset — this is what we do.

What We’ve Built

Enterprise ROI Calculators

Coviant Software MFT ROI Calculators — a suite of interactive tools that let enterprise buyers calculate the time and cost savings of switching to Diplomat MFT. These aren’t simple form-based calculators. They’re sophisticated tools with dynamic inputs, real-time calculations, conditional logic, and results presentations designed to move buyers through the decision process.

The results: 200+ enterprise leads generated directly through the calculators. Over £2M in attributable sales pipeline. The calculators became the highest-converting pages on the Coviant website and earned natural backlinks because they were genuinely useful tools, not just marketing collateral.

Drink Driving Calculator for Motoring Defence Solicitors — an interactive tool that helps people estimate whether they’re over the legal limit based on their drinks, body weight, and timing. This type of calculator serves a dual purpose: it provides genuine value to someone in a stressful situation (building trust and brand association), while capturing high-intent traffic from people who may need a motoring defence solicitor. The page ranks for competitive drink driving calculation terms and drives qualified leads for the practice.

WordPress Plugin Development

Roofing Cladding & Building (roofingcladdingbuilding.com) — this Southampton business came to us after their site had been badly hacked under their previous agency’s watch. Beyond the security cleanup and hardening, we developed custom WordPress plugins to extend the site’s functionality — improving user experience, adding features the off-the-shelf plugins couldn’t deliver, and ensuring the whole platform was robust enough to resist future attacks. The result is a stable, fast, secure site with bespoke functionality.

AI Assistant Plugin

SEO Strategy AI Knowledge Agent — the “Ask Our AI” feature on this site is a custom WordPress plugin that connects to a governed AI system trained on our methodology and content. It handles visitor questions, qualifies leads, and demonstrates our AI expertise in real-time. Built with proper WordPress architecture — hooks, filters, database abstraction — so any developer can maintain it. Learn about our AI Knowledge Agent approach →

Full Production Platform

seostrategy.co.uk — the most comprehensive example of what vibe coding produces. A custom WordPress theme with a content scaffold system that auto-deploys and version-controls 50+ pages, automated JSON-LD schema output for FAQPage, HowTo, Service, VideoObject, BlogPosting, and Speakable markup, RankMath integration via PHP filters, and the AI assistant plugin. 13,631 lines of production code. Independently valued at £20,000–£50,000 with architecture quality rated 8/10. Built in approximately six weeks. Read the full case study →

Why Vibe Coding Isn’t Just “Using ChatGPT”

There’s a critical distinction between prompting an AI tool and vibe coding as a development methodology. Pasting code into ChatGPT and copying the output is prompt engineering. Vibe coding is a sustained collaborative workflow: defining architecture, iterating through hundreds of refinement cycles, testing in production, debugging edge cases, and maintaining strategic oversight throughout.

The seostrategy.co.uk platform went through 200+ iteration cycles across multiple development sessions. Each cycle involved reviewing output, identifying issues, providing targeted feedback, and verifying fixes. The AI accelerated implementation; the human expertise determined what to build, why, and how to validate it.

This is why experience matters more in vibe coding than in traditional development. A developer with 20 years of experience directing AI tools produces fundamentally different output than a beginner. The AI amplifies existing expertise — it doesn’t replace it. The gap between “AI-generated prototype” and “production-ready system” is exactly the gap that human expertise closes.

What We Build

Interactive Calculators & Tools

ROI calculators, cost estimators, assessment tools, comparison engines — interactive assets that serve a genuine purpose for your audience while generating leads and earning backlinks. Our Coviant ROI calculators prove the model: useful tools that visitors actually engage with, producing 200+ leads and £2M+ pipeline. These work across any industry where buyers need to quantify a decision.

WordPress Plugins

Custom plugins that extend WordPress beyond what off-the-shelf solutions offer. Built with proper WordPress architecture — action hooks, filter hooks, database abstraction, admin UI — so they’re maintainable by any competent developer. From simple functionality extensions to complex systems like our AI assistant plugin.

CRO & Conversion Assets

Page enhancements that turn visitors into leads. Interactive elements, dynamic content, form optimisation, and conversion-focused features built directly into your site rather than bolted on through third-party tools. Integrated with your existing WordPress theme and CRO strategy rather than fighting against it.

Complex Custom Builds

Full production platforms, custom themes, content management systems, and bespoke web applications. If it runs on the web and requires more than a page builder can deliver, we can build it. Our own platform is the proof of concept — 50+ pages, automated schema, version-controlled content deployment, and an AI integration layer.

The Development Process

Every vibe coding project follows a consistent methodology, adapted to scope:

Architecture first. Before any code is written, we define the structure: what needs to be built, how the components connect, what the data model looks like, and how it integrates with your existing systems. This is the phase where 20 years of experience matters most — AI can’t make architectural decisions that require understanding your business, your users, and your technical constraints.

Iterative development. Building happens through rapid iteration cycles — typically 50–200+ cycles depending on complexity. Each cycle produces working output that’s reviewed, tested, and refined. Problems are caught and fixed in real-time rather than accumulating through a traditional sprint cycle.

Production testing. Everything is tested in real conditions before delivery. Not just “does it work” but “does it work at scale, on mobile, with real data, under load.” Edge cases are identified and handled. Security is verified. Performance is measured.

Handover and maintenance. The code follows standard conventions and is fully documented. Any competent developer can maintain, extend, or modify the output. You’re never locked into a dependency on us — the code is yours, it’s clean, and it’s maintainable.

Who This Is For

Businesses that need something built that goes beyond what a standard web design project covers. SaaS companies that want interactive tools to drive pipeline. Law firms that need compliance calculators to capture high-intent traffic. Enterprise companies that need custom integrations. Marketing teams that want conversion assets that actually convert.

If you can describe the tool or feature you need, we can almost certainly build it — faster and more cost-effectively than a traditional development agency, with the SEO architecture and structured data built in from the start.

Frequently Asked Questions

What is vibe coding?

Vibe coding is AI-assisted development where a senior practitioner works collaboratively with AI tools to build production-quality software. It's not pasting code into ChatGPT — it's a sustained methodology involving architecture decisions, hundreds of iteration cycles, production testing, and strategic oversight. The term was coined in 2025 and has quickly become the industry standard description for this approach. See our vibe coding case study.

How much does vibe coding cost compared to traditional development?

Significantly less for equivalent quality. A custom WordPress build that might cost £20,000–£50,000 through a traditional agency can be delivered for a fraction of that through vibe coding, because the implementation timeline is compressed without sacrificing quality. Specific pricing depends on scope and complexity — we quote every project individually after understanding what you need.

Can you build a calculator for my business?

Almost certainly yes. We've built ROI calculators for enterprise software (generating 200+ leads and £2M+ pipeline), drink driving calculators for law firms, and various assessment and estimation tools. If your buyers need to quantify a decision — cost savings, ROI, compliance scores, eligibility — a calculator is one of the highest-converting assets you can build. They also earn natural backlinks because they're genuinely useful.

Is vibe-coded output production-quality?

Yes, with the right human expertise directing it. Our site comprises 13,631 lines of production code, an independent valuation of £20,000–£50,000, and architecture quality rated 8/10. The critical variable isn't the AI — it's the human. A developer with 20+ years of experience using AI tools produces fundamentally different output than a beginner. Vibe coding amplifies existing expertise; it doesn't replace it.

Can another developer maintain vibe-coded work?

Yes. All code follows standard WordPress conventions, uses clear naming, and is structured for long-term maintenance. Our theme uses a scaffold system with proper hooks, filters, and database abstraction. Any competent WordPress developer can maintain, extend, or modify the codebase — they wouldn't know it was vibe-coded unless told. You're never locked into a dependency on us.

What's the difference between your web design service and vibe coding services?

Our AI web design service is for businesses that need a website built — from local business sites to complex custom platforms. Vibe coding services cover everything beyond a standard website: interactive calculators, WordPress plugins, CRO tools, conversion assets, and complex custom development. Many projects involve both — a website build with interactive tools integrated.

How long does a vibe coding project take?

It depends on complexity. A focused calculator or interactive tool can be delivered in 1–2 weeks. A WordPress plugin with admin UI and database integration might take 2–4 weeks. A full production platform like our own site took approximately 6 weeks. The compressed timeline compared to traditional development is one of the core advantages — you get working output faster because iteration cycles happen in real-time rather than through ticket queues and sprint planning.

Can you integrate with my existing systems?

In most cases, yes. We've built tools that integrate with WordPress, CRM systems, and third-party APIs. The architecture-first approach means we understand your existing stack before writing any code, so integrations are designed properly rather than hacked together.
