The website development company that picks the right tool for your business
ActiveSet designs and builds websites, web applications and online stores for companies in the US, UK, Canada and Australia. We work in four stacks, React, Astro, Webflow and Shopify, and tell you plainly which one fits your goals, your team and your budget before any code is written.
Website development services from a company that builds to last
ActiveSet is a website development company for businesses that need more than a template. We design and build marketing websites, web applications and e-commerce stores, then keep them running, from the first wireframe to the fiftieth update.
Every project starts with a written scope and a fixed price: what we will build, how it will be structured, what it will cost and when it will ship. You see the plan before you commit, and you own the code, the design files and the accounts when we are done.
Four stacks. We recommend the one that fits.
Most agencies sell the one platform they know. We work across four, so the recommendation is based on what you are trying to achieve, not on what we happen to prefer.
React development
Astro development
Webflow development
Shopify development
Who we build for
Businesses in the US, UK, Canada and Australia that treat their website as a business asset rather than a formality.
Remote across US, UK and Australian time zones, with overlap hours agreed at the start of each project.
B2B and SaaS companies
A marketing site the team can update weekly, and sometimes a product front-end built in React alongside it.
E-commerce and D2C brands
Launching a store, replatforming to Shopify, or rebuilding a theme that has grown slow and fragile.
Professional services firms
Legal, financial, consulting and healthcare teams that need a credible, fast, accessible site with clear paths to enquiry.
Funded startups
From Figma to a live site in weeks, with a structure that will not need throwing away at the next round.
Established businesses
A dated site losing ground on mobile, page speed or search, rebuilt without losing what already works.
Our terms, in writing.
Six commitments that sit in every proposal we send, whichever platform we recommend.
Platform-neutral advice
We build in React, Astro, Webflow and Shopify, so we have no reason to push one. The recommendation is written down, with the trade-offs, before you sign.
Written scope, fixed price
Pages, templates, integrations, deliverables and exclusions, quoted as a fixed price. If the scope changes, the price changes in writing.
Built for whoever comes next
Clean class systems in Webflow, typed components in React, documented CMS schemas. Your next developer can pick it up without calling us.
Performance by default
Static-first rendering, optimised images, minimal JavaScript, Core Web Vitals checked before launch. We cannot promise a ranking; the site will never be the reason you miss one.
You own everything
Code repositories, Webflow and Shopify accounts, domain and hosting, all in your name from day one.
One point of contact
A single project lead, a shared board you can see at any time, and a short written update every week until launch.
How a project runs
Seven steps, each with a named output. Design is signed off before development, and launch comes with a 30-day window for fixes at no extra cost.
Discovery call
What the site must do, who will maintain it, what exists today. A platform recommendation and budget range within two business days.
Design
You review at both stages. Signed off before development begins, so the build is not redesigned mid-way.
Quality assurance
Cross-browser and device testing, accessibility, forms and integrations, Core Web Vitals, and a full redirect map if we are replacing a site.
Ongoing support
A monthly retainer if you want us on call for updates, new pages and improvements.
Scope and estimate
Pages, templates, integrations, content responsibilities, timeline and a fixed price. Revisions are expected; nothing starts until it is agreed.
Development
Built on a staging URL you can view at any time, with a weekly written update and a shared task board. Content entry runs in parallel, so launch is not held up by copy.
Launch and handover
DNS, analytics and Search Console, a recorded CMS walkthrough, written documentation and a 30-day fix window.
Which platform is right for you?
It depends on what the site has to do, who will maintain it, and how much custom logic it needs. Use this as a first pass; the discovery call settles it.
The simplest platform wins
If it meets the requirement, the simpler stack is the one we recommend. Complexity you do not need is cost you pay forever.
No surprises after the estimate
If the recommendation changes during discovery, we tell you before the estimate, not after.

Frequently Asked Questions
It depends on platform, page count, custom functionality and content readiness. A Webflow marketing site, a React application and a Shopify store are different kinds of work with different price ranges. Every ActiveSet quote is a fixed price against a written scope, so you will know the number before work starts. Send a brief and we will give you a range within two business days.
A focused marketing site on Webflow or Astro typically runs several weeks from kickoff to launch; application and e-commerce projects take longer depending on integrations and content. The timeline is set in the proposal, and the most common cause of delay is content arriving late, which is why we plan content entry alongside development.
Design agencies focus on how a site looks and feels; development companies focus on how it is built and how it performs. ActiveSet does both: design in Figma, then a production build on the right platform. You do not need a second vendor to turn designs into a working site.
If your team will update the site often and you do not need custom back-end logic, Webflow is usually the better choice. If the site is an application, has complex data, or needs integrations Webflow cannot host, custom development in React or Astro is the right call. We will recommend one and explain why.
Yes. Every build is designed and tested across phone, tablet and desktop breakpoints before launch. Responsive layout is part of the standard scope, not an add-on.
Yes, with a redirect map and metadata migration built into the project. We audit which URLs currently earn traffic, preserve or redirect every one of them, and verify the site in Search Console after launch. We cannot guarantee rankings, but we can make sure the rebuild does not throw away what already works.
Yes. Our retainer gives you a fixed block of development hours each month, a shared backlog and a committed response time. It covers all four platforms we build on.
Yes. ActiveSet works with clients in the United States, United Kingdom, Canada and Australia. We agree overlap hours at the start of each project and run everything through shared tools, so distance does not slow the work down.
You do. Code repositories, Webflow or Shopify accounts, hosting, domain and design files are all set up in your name and handed over at launch.
Usually, yes. We start with a short technical audit to assess the build quality, then quote either a takeover with fixes or a rebuild, whichever is more cost-effective for you.
