GCDWebServer is a lightweight HTTP 1.1 server for iOS, macOS, and tvOS. It serves as an embedded network server for Apple platforms, allowing developers to handle incoming requests through custom synchronous or asynchronous handlers.
The project includes a WebDAV server implementation for remote file management, directory browsing, and synchronization using standard network clients. It also provides a web-based file manager that enables users to upload, download, and organize files within an application sandbox via a browser.
Additional capabilities include gzip compression, JSON processing, and the ability to restrict access using Basic and Digest authentication. The server supports serving static content with range requests, parsing multipart form submissions, and generating dynamic HTML through template-based injection. High-volume data is handled via stream-based payloads to prevent memory exhaustion.
