Web Performance

Audits, Consulting & Development

Web performance is essential for any online business. It has a high impact on the revenue, helps retain users on the site, saves server costs, and is a sustainable contribution to environmental protection.

How fast is fast enough? That is important to know. How much do 100 Milliseconds impact your conversions or revenue? How do we monitor your site and prevent regression? Let's work out together your impactful metrics, the best monitoring, and accountability for issues. We create a performance culture in your company.

Web Sustainability

Audits, Consulting & Development

How ecologically sustainable is a site? Why is this important, and how can a page be programmed sustainably in a cost-effective manner. Digital technologies are currently responsible for 4% of global greenhouse gas emissions, and our websites are getting bigger and bigger.

A sustainable site saves server costs and contributes to environmental protection. A switch to a more environmentally-friendly site is also possible without any restrictions. We have a social responsibility to keep our digital footprint as low as possible. In addition, sustainable websites are also more efficient and thus stimulate online business.
