What does a web development project with Tentharc involve?
Web development
We design and build marketing sites, product sites, and web applications on Next.js — server-rendered, accessible, measured, and deployed to a URL you own. A typical site takes three to six weeks.
Typically 3–6 weeks
How it works
Most sites fail commercially before they fail technically. They load fine and say nothing a buyer needed to hear. So we start with the questions your customers ask before they buy, decide which page owns each one, and only then design anything.
The build is Next.js, server-rendered by default. That is a deliberate choice rather than a fashion: content that only appears after JavaScript runs is content that a lot of crawlers and assistants never read. Everything we ship is in the HTML.
You watch the whole thing. There is a staging URL from the first week and an update every Friday saying what shipped, what is next, and what we are waiting on from you.
This is the right fit when
- You need a site that sells, not a brochure
- Someone non-technical has to edit it afterwards
- Being found matters as much as looking good
What is included
- Discovery call and a written scope you sign before anything is built
- Design direction — two routes, one chosen, applied across the site
- Responsive build, WCAG 2.2 AA target, Core Web Vitals in the green
- A content model, so you can edit your own copy without calling us
- Forms, lead capture, and analytics wired up and tested
- Deployment to Vercel with a preview URL on every change
- Handover documentation and a recorded walkthrough
Not included, unless quoted separately
- Copywriting beyond structural placeholders
- Photography, illustration, and video
- Content updates after handover, unless you take a care plan
- Data migration from a system nobody has described yet
Saying what is out of scope is not us being difficult. It is the single cheapest way to avoid the argument that ends most agency relationships.
Common questions
- How long does a website take to build?
A marketing site of five to eight pages typically takes three to six weeks from signed scope to launch. An application with accounts and real product logic typically takes six to fourteen weeks.
The single most common cause of delay is content. If copy, logo, and photography are ready when the build starts, projects land on the date we quoted.
- How does Tentharc price projects?
We price a fixed amount per phase, agreed in writing before work starts, rather than billing by the hour. Hourly billing penalises us for working quickly and makes clients hesitant to ask questions, which is the opposite of what a good project needs.
Scope changes are quoted as a written change order and approved before any work on them begins — including small ones.
- What happens after the site launches?
You own everything, and you can walk away. The code, the content, and the accounts are yours once the final invoice is paid, and the handover documentation is written to be enough on its own.
Most clients take the monthly care plan instead: dependency and security updates, uptime monitoring, verified backups, a fixed pool of change hours, and a committed response time.
- What technology does Tentharc build on?
Next.js and TypeScript for the front end, Supabase and Postgres for data and authentication, Vercel for hosting, and PostHog for analytics. Mobile work is React Native with Expo.
The framework choice follows from the search work rather than from preference: server-rendered HTML is what crawlers and AI assistants can actually read, and a client-rendered application works against the thing we are selling.
- Will I be able to edit the website myself?
Yes. Every site includes a content model matched to how you actually work, so a non-technical person can change copy, images, and pages without asking us.
We cover it in a recorded thirty-minute walkthrough at handover, so it is there when you need it in four months rather than in a call you half remember.
- Who owns the code and the accounts?
You do. Hosting, database, analytics, and domain accounts are created in your name wherever possible, and we work inside them with access you grant and can revoke.
It means leaving us is a permissions change rather than a migration project. We think that is the only honest way to run a studio.

App development
Yes. We build cross-platform applications with real product logic — accounts, permissions, and data — using React Native with Expo for mobile and Next.js with Supabase for web. A first version typically takes six to fourteen weeks.
AEO & SEO
Answer engine optimisation is the work of becoming a source that AI assistants cite when they answer a question, rather than a result buried on a page nobody scrolls. It shares its foundations with SEO — crawlable, fast, well-structured pages — but the target is the citation, not the ranking.
