Claude Code is an agentic coding tool from Anthropic, the company behind the Claude family of AI models. It runs in a developer’s terminal and works directly inside a codebase - reading files, writing and editing code, running commands, and using tools - rather than just suggesting snippets in a chat window.
Anthropic introduced it in 2025, first as a research preview alongside a new generation of Claude models and then more widely as the models grew capable enough to carry real engineering work end to end. It quickly became one of the most-used ways professional developers actually build with AI, precisely because it operates on a real project the way an engineer does.
For a web studio that is the unlock. Earlier AI tools could autocomplete a function; Claude Code can take a researched brief and a design and build the site - typed, tested, accessible - then keep changing it on request. Paired with senior judgement on strategy, design and what’s worth building, it’s how we ship sites in days that a template could never match and a traditional agency would quote months for. It’s the engine; the understanding is still ours and yours.
It’s worth being clear about what Claude Code is not. It isn’t a website builder: there’s no theme gallery, no drag-and-drop canvas, no hosting plan attached. And it isn’t ChatGPT: a chat assistant answers in text and leaves you to do something with it, while Claude Code acts on a real project directly.
The tool itself is the cheap part, and we carry that cost, so it never lands on you. What matters to you is what its existence changed: the labour of building and changing a website collapsed, and that shows up in your quote and in how fast a change goes live.
For years, building a website meant choosing a builder - Webflow, Framer, WordPress, Duda. We built on all of them, and we still build on Duda where hands-on editor access is genuinely the priority. Claude Code is the step beyond: the same speed of change, without the platform ceiling, the subscription or the lock-in.
