High-performance

Quality that pays for itself Not a template. Not a factory.
Custom systems built by a software engineer with nearly 20 years of experience.
Every project starts with understanding your business logic, your constraints, your actual needs.
No copy-paste, no assembly line workflow, no AI doing the work that matters in our place.
We architect solutions. We don't put features on top of each other.
- Performance that lasts
- Costs that don't inflate with scale
- Built to comply (GDPR, EAA, EU standards included)
- Lighter footprint. Faster load times. Lower bills.
Performance built into architecture, not added later
- 53 % of users abandon a site that takes longer than 3 seconds to load.
- 8.6 s is the average mobile loading time as of 2026.
You lose up to half your audience before they see anything.
Every YellowCraft solution is designed to meet Core Web Vitals.
- LCP ≤ 2.5s
- Fast main content
- INP < 200ms
- Smooth interactions
- CLS < 0.1
- Stable layout
You stop losing visitors to slowdowns.
Optimized architecture, lower bills
Every byte transmitted, every server request, every compute hour has a cost.
A poorly architected site can consume 3x to 5x more resources than needed.
YellowCraft builds lean architectures. Less code, fewer requests, less wasted compute.
Result: your hosting needs drop.
What you get:
Predictable, lower monthly bills. Less money to your hosting provider, more for your growth.
Accessibility is not optional. It never was.
- 16 % of the global population lives with a significant disability.
- +30 % benefit indirectly: elderly users, colour blindness, dyslexia, visual fatigue.
Up to 40 % of your market depends on accessibility. In the EU, non-compliance with WCAG also leads to fines.
YellowCraft designs every interface to meet WCAG and EN 301 549 standards.
- Contrast, readability, keyboard navigation
- Proper semantic HTML structure
- Screen reader compatibility
- Performance on low-bandwidth connections
Built-in compliance. No legal risk. A broader audience without extra marketing spend.
Slow tools, wasted time
- 85 % of desk workers face daily slowdowns.
- 64 % say their tools actively tank productivity.
A bloated or poorly built tool is expensive: it steals your time.
YellowCraft builds tools with strict engineering constraints.
- Lean architectures
- < 200ms on critical actions
- Optimized DB/queries
- No more blocked loads
- Structured APIs
- Reliable integrations (CRM, ERP, SaaS)
- No technical bloat
- Fewer bugs, simpler maintenance
Work flows again. Your teams produce instead of waiting.

FAQ
I can get a website for €250 on freelance platforms. Why would I pay more for your services?
Fair question. Honest answer: if your goal is simply to get online at the lowest possible cost, those solutions can be a good fit.
You just need to understand what you're buying at that price.
In most cases, it's a template-based website (Wix, WordPress...) with fonts and colours swapped, put together in a few hours by someone who doesn't understand your business.
The real cost comes later:
- Security: common targets for attacks, €300 to €20,000+ in breach cleanup costs.
- Mandatory maintenance: plugins, bugs, updates.
- Performance: slower loading times, fewer conversions, silent Google demotion.
- Full rebuild likely within 1–2 years.
If your business depends on this website, we don't recommend going with a low-cost solution.
With YellowCraft, you pay more upfront because you avoid recurring structural costs tied to poorly suited architecture.
How long will it take? I need to launch quickly.
Timelines depend on the project and what you provide.
Typical ranges: 1 to 4 weeks for a landing page, 3 to 10 weeks for a showcase site, 1 to 3 months or more for an application.
A precise timeline is set from day one, with visible milestones and a live project tracking dashboard.
- Realistic ranges, never overpromised.
- Tight deadline? We reduce scope smartly.
- If it's not feasible in time, we tell you upfront.
What if I want to manage it myself afterwards? Will I be tied to you after delivery?
You're independent from day one. It's not optional.
Every project includes documented code, explained architecture, and maintenance guides.
- No technical lock-in.
- No hidden commitments.
- Your code is yours, unconditionally.
Ongoing maintenance is optional, you're free to manage everything without us.
You can continue alone, bring it in-house with your own team, or work with another provider.
If you keep us, it's because you see the value, not because you have no choice.
Why not use a CMS like WordPress or Wix?
You can. The real question is whether it fits your needs.
Vanilla WordPress is performant and secure. Problems usually appear once features expand. A blog is simple. A corporate website with business integrations is another story.
That's when plugins enter the picture, and so do the complications: cascading dependencies, security gaps, degraded performance, Core Web Vitals slipping out of reach.
At YellowCraft, if WordPress is the right solution for your case, we deploy it, but with the same standards as a from-scratch build.
- WordPress by default = growing risk with complexity.
- WordPress done right = excellent tool with real guarantees.
- YellowCraft = we do it right, or we build custom.
We hear a lot about "green" and "ethical" tech. What does that actually mean in your case? What's in it for us?
Building a more responsible web is what led to the creation of YellowCraft. For us, this isn't marketing, it's the foundation of how we design and build software.
Environment: Digital technology accounts for 3.6% of Europe's carbon emissions, nearly half of that impact being data centres alone, a figure that could triple by 2050.
Data governance: Only 8% of European data is stored within the EU, exposing the remaining 92% to extraterritorial laws such as US FISA regulations. The Cloud Act further intensifies this growing concern.
Accessibility: Despite being a powerful tool for connecting people, the web has excluded large portions of the population living with disabilities or vulnerabilities for too long.
We actively work to reverse those trends.
- Minimalist websites30–60% less data transfer, lower energy use and hosting costs.
- Green hosting100% renewable-powered infrastructure (through our partners).
- Sovereign dataEU hosting, GDPR by default, no opaque dependencies.
- Accessibility built inWCAG compliance by default, wider audience reach.
- For youless pollution, lower costs, more control.

Do you use AI?
Generative AI has upended our habits and quickly become, whether we like it or not, an essential tool for many professions, including software developers.
Today, it already helps us work more efficiently, while raising important concerns around privacy and environmental impact.
We use it carefully to improve productivity while strictly limiting the risks we identify.
- Models trained only on public or internal datasets.
- Local execution or on secure European infrastructure.
- Optimized usage to avoid unnecessary computation.
- No AI-generated illustrations, logos, or visual assets.
- No AI-written content or emails.
