Web development built for speed and search

A London web design and development agency that treats performance, accessibility and SEO as requirements, not extras — marketing sites from £5,000.

Solutions we've built power teams at:

  • Amazon Web Services
  • Auto Trader
  • Cedars-Sinai
  • Jet2holidays
  • Jaguar Land Rover
  • Dover Street Market
  • Dexters
  • Lookers

Every step, with a team who's done it before

Most web shops treat speed, accessibility and SEO as extras you pay more for later. We treat them as the brief. Whether you need a marketing site or a web app people log into, it's built fast and search-ready from the first line of code.

  1. Site or app

    We work out whether visitors mostly read and enquire — a website — or log in and do things — a web app. Plenty of projects are a site now with an app added later; we build so that path stays open. Free, before you commit.

  2. Scope & quote

    You get one fixed price for the work: from £5,000 for a marketing website, from £15,000 for a web application with accounts, dashboards and custom features. Analytics and SEO groundwork are in the number, not bolted on.

  3. Design & build

    We design and build for fast load times, clean structure and accessible markup — the things search engines actually reward — and set it up so your team can edit copy and pages without calling a developer for every comma.

  4. Keep it sharp

    After launch, support runs from £400 a month to keep the site fast, secure and current — or you take the code and run it in-house. It's yours on payment, no strings.

Web work for names you know

Campaign sites built for Amazon Web Services programmes, an interactive quiz shipped for Dogs Trust, and a web app that finds indie games from a plain-English description — the same engineering standard from brochure site to full application.

  • AWS programme websites

    Campaign websites for AWS's community programmes — Girls' Tech Series, CloudRoom, CloudPrep and more — designed and built with events agency Marble LDN to bring young people into tech.

  • Dogs Trust

    An interactive quiz game for Dogs Trust — a self-contained, browser-based experience with a guiding character, tailored results and built-in tracking, built for the charity's lead agency to drop into its site.

    A game-discovery web app for indie-games startup Indie-Go. Describe the game you want in plain words and browse tailored recommendations, with rich game pages and a favourites library.

The tech

The web stack, honestly labelled — what we've shipped client sites and apps with, what we work with on request, and what this very site runs on.

  • React

    We've built production web software with React — our default wherever the interface does real work.

  • Next.js

    We work with Next.js where server-side rendering earns its place — and we'll say when a simpler static build serves you better.

  • Node.js

    We work in Node.js where a JavaScript backend fits your team — though most of our shipped backends are Django, and we'll tell you why.

  • Django & Python

    Go Quest's city platform runs on a Django backend and admin CMS we built — our workhorse for web applications with real logic behind them.

  • Progressive web apps

    Skamper's web app is a PWA we rebuilt — installable and app-like without the app-store toll, which was right for the product.

  • Astro

    This site runs on Astro — we ship almost no JavaScript to your visitors, which is a large part of why fast sites are fast.

  • Embeddable JavaScript

    Dogs Trust's interactive quiz shipped as a self-contained JavaScript package — built to drop into a site we don't control.

  • AWS & Google Cloud

    The sites and apps we build deploy to AWS and Google Cloud infrastructure we already run for clients — so launch day isn't the first test.

  • And much more

    This is what comes up most often, not a limit. Bring us something that isn't on this list and we'll get up to speed on it — working with something new is the job, not an obstacle.

What our clients are saying

Real reviews from clients we have delivered for, on Clutch and elsewhere.

  • The enthusiasm, understanding of our mission, and passion from the first few minutes of the call were the deciding factors in choosing CodeLeap. Within 3 months of our app launching, we had over 1,500 downloads, appeared in leading publications from Forbes, The Metro, Marie Claire, Women's Fitness and many more, and started raising further investment.
    Charlie CEO, Becon
  • They are incredibly diligent in the quality of work they produce, and go above and beyond when it comes to solving issues faced within the project, and to ensure we meet strict project deadlines. You never feel like you are one of many clients, and they ensure they are always there to help with any need you have, no matter how big or small.
    Amelia Parmiter Marketing Manager, AWS - Marble
  • CodeLeap made me feel like my options were limitless in terms of what could be achieved, which was critical to me as we were creating something very unique. I'm glad I chose Codeleap over a large corporation as the personable approach resulted in a smooth and pleasant experience.
    James CEO, Bearable
  • Working with CodeLeap was a very good experience from both a professional and personal point of view. These people know what they are doing and are both efficient and clever and made a good partner. I wouldn't hesitate to recommend CodeLeap.
    John CEO, Neurometrics-Diab
  • CodeLeap adds so much value and goes above and beyond what I expected. CodeLeap's team is very flexible with all the different requests we've put in front of them. They've also been great with the whole business side of things, and being able to forecast for this industry is really helpful. Overall, I'm completely satisfied with their work — they've been incredibly helpful.
    Johanne CEO, Cherry
  • Their flexibility and focus on quality were outstanding.
    Mike Fenna CTO, Kite Insights
  • Marcelo has been wonderful throughout the process and we are very happy.
    Amrit Director, Energy Company
  • Absolutely FANTASTIC. This is very much what I had in mind. We're very pleased with your team, thank you all very much.
    Rich Director, Legal Company

Any questions? We're here to answer

Everything you might want to know before starting a project with us.

  • Our marketing websites start from £5,000, designed and built — fast, accessible, SEO-ready and easy for your team to update. A web application with custom functionality starts from £15,000. Fixed price, agreed before we start.

  • If visitors mostly read and enquire, a website; if they log in and do things, a web app. Plenty of projects are a site now with an app added later — we build so that path stays open.

  • No — nobody honest can. What we control is what search engines reward: fast load times, clean structure, accessible markup and content that answers real queries. We build all of that in from the first line of code.

  • Yes — that's a requirement, not an extra. We build so your team can change copy, images and pages without calling a developer for every comma.

  • We offer ongoing maintenance and support, typically starting from £400 per month, so the site stays fast, secure and up to date. You won't be handed something and left to fend for yourself.
