Public APIs is a community-curated GitHub repository listing free, publicly accessible APIs across a wide range of categories, with auth type, HTTPS, and CORS noted for each entry. It's a browsable reference, not a library to install.

Awesome Python is a curated list maintained at vinta/awesome-python that groups Python frameworks, libraries, tools, and other resources into 14 categories, from AI & ML to Security and Other. The README calls it an opinionated guide rather than an exhaustive one, and points readers to a companion site, awesome-python.com, for searching and filtering entries instead of scrolling the raw file.

Awesome-Selfhosted is a community-maintained GitHub list at awesome-selfhosted/awesome-selfhosted that catalogs Free Software network-service and web-app projects meant for running on a server you control rather than someone else's cloud. Entries are grouped by category, each tagged with a license and a language or deployment option, and the project keeps proprietary alternatives on a separate Non-Free page.

torvalds/linux is the GitHub git tree for the Linux kernel's C source code, the hardware-facing layer every Linux distribution builds on top of. Its README sorts documentation by contributor role — developer, security expert, hardware vendor, sysadmin, maintainer, and more — instead of listing kernel features.
