What can I say! We are over the moon with our new company website. :) Code23 have most definitely got the 'WOW' factor. Eye catching design, superb user experience and extremely well project managed end-to-end. It was hassle free and the end result is far better than we ever imagined. I can't recommend enough. Thank you to James and the team. Top service!

How we engage

Fixed-scope project
Scoped after Blueprint. Milestone payments. 90-day warranty on the build.

Phased delivery
Discovery first, then build phases with clear gates. Scope locked per phase.

Support retainer
Managed hosting, monitoring and continuous improvement from the team that built it.

- 01
Map
Users, jobs-to-be-done, brand constraints and the decisions the interface must make obvious.
- 02
Blueprint
Flows, information architecture and design principles - scope and success criteria written down.
- 03
Build
UI and prototypes move in parallel with engineering. Seniors direct; agents accelerate production artefacts under review.
- 04
Harden
Usability review, accessibility checks and design QA against the live build - gaps close pre-Launch.
- 05
Launch
Final visual QA, content fit and a named owner for post-launch design debt.
- 06
Evolve
CRO, UX audits and system extensions follow usage data - design stays on the product, not in a finished PDF.
What clients say
Joe and the team at code23 have done a fantastic job helping us design and build our new website. I feel they really captured the quality of the Draks brand. Would highly recommend.
Code 23 are a first class web design agency. James, Joe and their team are a pleasure to work with and made the process very easy from a client perspective. I was impressed with their ability to work up briefs quickly, their ability to keep to deadlines and the quality of the site that they delivered. They are highly recommended and an agency we will continue to work with on other projects.
Code23 were the best company I could have found to start my new business website. Despite it being a relatively hard to explain idea, James and the team understood exactly what the site's function was and built a brilliant bespoke design to fit my needs. Even going the extra length to recommend ideas and tweaks that I hadn't thought of to improve the way it runs and deliver something that I am proud to have as the main online front for my business
Code 23 took the time to understand our companies needs and designed our website accordingly. James was always available to guide us through when I needed help. The design was bold and engaging and with help from Code 23 we have been able to keep it updated and fresh. A great company to work with.
Pleasure to work with and very happy about the design element, general service and performance of Code23
Questions about Product Design
Is UI/UX replaced by AI?
No. AI speeds production; it does not own taste, risk or accountability. Seniors run critique and own the direction - agents multiply variants and system upkeep inside that remit.
How much does product design cost?
Discovery depth, number of flows and whether a design system is included set the band. Blueprint defines the design scope, then current pricing is confirmed before the work begins.
How long does a UX design project take?
Timeline follows the Blueprint cut: audit-only work is shorter; full discovery through design system takes longer. Dates are agreed with the scope.
Do you hand designs to another studio to build?
No. Design and build sit in the same agency - that is how UI stays honest against real databases and edge cases.
How do AI agents sit in your design process?
Agents synthesise research notes, draft variants and keep design-system files tidy under senior direction. Workshops, critique and risk stay with humans - agents multiply production work inside a clear remit.
