Web Development
Web development covers the services, documentation and projects people use to build and ship websites. Listings include frameworks and libraries, hosting and deployment platforms, analytics and performance tools, and the reference sites that explain how the web works. Some entries are official documentation, some are code repositories, and some are community forums or learning paths. Useful things to check are the current release, the licence, how active the project is and how clearly the docs explain setup and limits. Tooling changes quickly, so read release notes and support status on the project's own site.
