ModelWeb is a Czech-language online resource for scale-modeling enthusiasts, bringing together hobby news, reference material, reviews, and links to the wider modeling community. Its extensive coverage spans aircraft, helicopters, ships, vehicles, railway models, figures, science fiction, and dioramas, with articles organized by subject and scale. Readers can browse kit previews, build reviews, walkarounds, decals, accessories, tools, and practical modeling guides, as well as updates from numerous manufacturers and specialist firms.

The site also features publication news and information about magazines such as REVI and Modelář, alongside books, events, competitions, and historical topics. Its directory connects visitors with modeling clubs, Czech and international hobby websites, blogs, special-interest groups, and other related resources. Recent posts include manufacturer updates and announcements about new magazine issues. Rather than presenting itself as a model-kit retailer, ModelWeb functions as an editorial and community-oriented portal, helping hobbyists discover products, learn about modeling subjects, and keep up with developments across the scale-modeling scene.
