Custom web development means building a website or web application around your business, instead of bending your business around a template. You get software that fits your workflows, connects to your systems and can grow with you, and that you can evolve without starting over. It’s the right choice when a website builder can’t handle your integrations, your traffic or your product logic. - Designed around your users and processes - Integrated with your ERP, CRM and payment tools - Built to scale with traffic and new features SEO-friendly by default Built to rank from day one A website only performs if people can find it. We build search performance into the architecture, so you don’t pay for an SEO rescue after launch. - Server-side or static rendering for instant, crawlable pages - Core Web Vitals tuned for speed on mobile - Semantic HTML, schema.org structured data and sitemaps - Accessible markup in line with WCAG - Analytics and Google Search Console from launch Proven in production From Prestashop to a custom platform For Efarmz, we led a team of three developers to rebuild the shop from Prestashop into a fully custom platform, scaled for record COVID order peaks and synced in real time with their ERP. The rebuild contributed to Efarmz winning the E-commerce of the Year award.

Ask the team directly. Ask us a question What does a web development company do? A web development company designs, builds and maintains websites and web applications. At Co-Labs that covers the full cycle: scoping with a product and a tech expert, UX/UI design, front-end and back-end development, integrations with your ERP, CRM or payment tools, hosting, launch, and ongoing maintenance and growth. How long does it take to build a website or web application? It depends on scope. A marketing website usually takes a few weeks; a custom web application or e-commerce platform usually takes a few months. Every project starts with a two-day Co-Thinking workshop that turns your idea into a scoped plan with a timeline. For reference, we co-built the EU's Rapid Alert System platform and took it live within a three-month deadline. How much does custom web development cost? Cost depends on the number of features, integrations and users the platform has to handle. Rather than quoting blind, we start with a two-day Co-Thinking workshop and give you a clear scope and estimate at the end of it. Projects can be billed at a fixed fee or, for ventures we believe in, partly in sweat-equity. Which technologies do you use for web development? We build mostly in TypeScript, with Next.js and React on the front end, and NestJS, Laravel or Python on the back end. For content sites we use static-first frameworks such as Astro. We deploy with CI/CD on the cloud provider that fits your constraints, and we start from open-source foundations so you are never locked into a black box. Will my website be SEO-friendly? Yes. SEO is built in from the first sprint, not added at the end: server-side or static rendering, clean semantic HTML, fast Core Web Vitals, structured data (schema.org), XML sitemaps, canonical URLs, accessible markup and metadata for every page. We also set up analytics and Google Search Console so you can measure what ranks. Can you migrate our existing website or online shop? Yes. We plan migrations so you keep your data, your URLs and your search rankings: content and product migration, 301 redirects, and integration with the systems you already run. For Efarmz, we migrated the platform from Prestashop to a fully custom solution, handled record COVID order peaks and integrated their real-time ERP. Do you maintain and improve the website after launch? Yes. With Co-Growth, the team that built your product keeps it secure, up to date and improving month after month: maintenance, monitoring, new features and growth work, on a fixed fee or on sweat-equity. Do you only work with companies in Brussels? No. Co-Labs is based in Brussels and works with startups, scale-ups, corporates and public institutions across Belgium and Europe, including projects for EU institutions.
