ZW3B is a web and network platform produced by LAB3W.FR, the Web and Networks Laboratory founded by O. Romain Jaillet-ramey. The project brings together a group of websites and internet services focused on distributing content, managing infrastructure, and developing online applications. Its platforms include ZW3B.FR for news, documentation, links, and videos; ZW3B.TV for video content; ZW3B.EU for summaries and news; ZW3B.NET for search; ZW3B.APP for API management; ZW3B.COM for web, FTP, and database service management; and ZW3B.BLOG, a blogging platform in development.

ZW3B.COM also provides account and administration tools for eligible members, including management of domains, virtual hosts, databases, and FTP accounts. The wider network operates Linux-based infrastructure across several countries, supporting services such as DNS, web hosting, email, file transfer, and databases. LAB3W describes its expertise as including information-system security analysis, IP networking, and web development. The project emphasizes a friendly community and a network of trust, and states that it does not charge members for access.
