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.
The environmental challenge
Digital technology accounts for 3.6% of Europe's carbon emissions. If nothing is done to curtail it, its environmental footprint could triple between 2020 and 2050. Data centres alone account for nearly half of that impact. Every slow website, every unnecessary request, every ghost plugin: that's wasted energy. For nothing.
Eco-design by default
Every project is built to use fewer resources. Minimal by design. No dead code. No unnecessary dependencies. No bloat.
- Lean code30–60% less data transfer
- Lean architectureslower server load = lower bills + lower carbon footprint
- Native performancefewer requests, less compute, less energy
Concrete outcome: a well-architected system consumes significantly less energy than a poorly optimized one.
Sustainable hosting
All our internal tools and hosted projects run on infrastructure powered by renewable energy. You remain free to use your own provider. If you'd like, we can help you choose a partner that guarantees 100% renewable-energy data centres.
Data governance: a growing concern turned strategic
Data management has become a major concern for companies and governments alike. Between regulations, SaaS dependency, and risks from extraterritorial legislation, more and more organizations are looking to regain control.
YellowCraft builds this constraint in from the start:
- Data hosted within the European Union
- Limited reliance on third-party services
- Architectures reducing external dependencies
- Tools chosen for privacy-by-default
Responsible use of 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.
Probably like you, we appreciate what these tools can do to help us, while being concerned about data privacy, the environmental cost of computation, and model training sources.
We deliberately refuse to use AI to generate illustrations, logos, and other graphics (diffusion models), or to write content and emails. We reserve AI for code assistance and information summarization (large language models).
When we do use AI:
- Models trained on public or internal datasets
- Execution locally or on secure European infrastructure
- Optimized usage to avoid unnecessary computation
Accessibility: a long-overlooked standard
Accessibility has been largely ignored for decades, despite existing standards (WCAG since 1999).
Most developers have never been trained. Engineering schools ignore it. Agencies too often treat it as "nice-to-have".
Today, the landscape is changing fast:
- Strengthened legal requirements in Europe (WCAG/EN 301 549)
- Rising user expectations
- Growing awareness
16% of the global population lives with a significant disability. Up to 30% more would benefit indirectly from accessible design (low vision, colour blindness, dyslexia, slow connections, elderly users). That's 40% of your potential market hitting sites that are "inaccessible by default."
YellowCraft builds accessibility in from day one (WCAG, EN 301 549), not tacked on later, at zero extra cost.
We also offer training for technical teams to:
- Understand the standards
- Fix common errors
- Build accessible systems long-term
Accessibility is no longer a "bonus." It's becoming the baseline.
Our partners: aligned governance
We select partners based on clear criteria:
- European or open-source technologies
- Transparent practices
- GDPR compliance without workarounds
What we're after: less dependence on opaque ecosystems. More control.
Partners we regularly work with:
- Hetzner (Germany)
- 100% renewable-powered data centres, GDPR-native
- Scaleway (France)
- Energy-efficient infrastructure, renewable-powered
- Mistral (France)
- AI models trained in Europe, zero lock-in, full transparency
- Proton (Switzerland)
- End-to-end encryption, zero tracking, data sovereignty
- Ecosia (Germany)
- ethical search engine, funding reforestation
Why European partners? Because they operate under European law. Data sovereignty, GDPR by default.
No US Cloud Act. No access under FISA regulations. No resale of your data.
What this means for you
- Lower carbon footprint: your systems consume less energy.
- Lower bills: reduced resource usage = lower hosting costs.
- Data sovereignty: your information stays in Europe, protected by law.
- Broader audience: accessible by default = no potential customer is excluded.
- Compliance assured: GDPR, accessibility, and security standards covered.
Sustainability is not an extra feature. It's the result of better engineering.
