We are Straffe Sites: a small, senior team around web developer Seppe. For more than 20 years we have built websites and digital products, today mainly with Astro, Storyblok, Vercel and AI agents under human control.
4.9/5 on Google26 reviewsYou don’t have to explain your story to an account manager first. In our first conversation, we talk about your business, customers, and goals; we then translate that into structure, design, and code.
We work with independent professionals and small businesses in Belgium and the Netherlands, mostly online and without jargon. Our work combines web development, web design, SEO, and AI & automation.
