What we build

End-to-end. Front to back.
Everything in between.

Fixed-price builds. You own the code outright — no platform lock-in, no SaaS subscriptions. Add monthly support if you want us on standby. Your call.

Websites & Web Apps

From landing pages to full web applications. Fast, conversion-focused, built on Next.js and deployed on the edge.

Mobile Apps

Cross-platform mobile apps with React Native. iOS and Android from a single codebase — no compromise on quality.

Dashboards & Analytics

Admin panels, internal tools, data visualisations. Complex interfaces made clean — auth, roles, real-time data.

APIs & Backend

Full custom backend — authentication, database, REST APIs, payment integration (Stripe, QuickPay, MobilePay), admin dashboard. Everything from scratch, nothing off-the-shelf.

3D & Interactive

Blender models, Three.js scenes, and interactive web experiences that make visitors stop scrolling. Custom scope.

Maintenance & Support

You own the code — no platform lock-in, ever. Add optional monthly support and we handle updates, security patches, new features, and priority fixes. Cancel whenever.

ADD-ONAlready have a site? Add payment integration.

You do not need a full rebuild to start taking payments. We add a fully branded checkout to your existing site — card payments, Apple Pay, Google Pay, and downloadable invoices. Your customers stay in your experience, start to finish.

Why custom-built

Not a template.
Not a subscription.
Yours, for real.

Most website builders lock you into their ecosystem. We don't. Every project is written from scratch — built around your business, owned by you, with no ceiling on what it can do.

The old way
Template you share with 10,000 others
Monthly platform fees forever
"That feature isn't in your plan"
Cookie-cutter design you can't escape
Platform shuts down — your site vanishes
Want a change? Call their support line
The SlothStudio way
Coded from zero, built around your business
You own the code. No platform fees — ever
Anything can be added — no ceiling
Your brand, your layout, your identity
Hosted where you want, independent forever
Changes in hours, not tickets and queues

No platform dependency

Your site runs on your own infrastructure. No Wix. No Squarespace. No Shopify. You're not a tenant — you're the owner.

Built to your exact spec

Booking system? Online ordering? Staff portal? Multilingual? Every feature is built specifically for how your business actually works.

Scales with you

Start with a landing page. Add a booking system later. Then a customer dashboard. Each piece built clean, without touching the rest.

One price — you own it

We quote the project, we build it, you pay once. No Wix fees, no Shopify cuts, no platform subscriptions. Add optional monthly support from us if you want someone on standby — otherwise you're free.

Tell me what you need. We scope it out, agree on the quote, and align on the plan — before a single line of code is written.

02

Build

I design and develop your product. You see real progress at each milestone — not silence and a finished product two months later.

03

Launch

We deploy, test across devices, and hand everything over. You own the code, the domain, the hosting. No lock-in, no ongoing dependency.
