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.

The Algorithms - Python is an open-source collection of algorithm implementations written in Python, maintained by the TheAlgorithms organization on GitHub. The README frames the whole project as a teaching resource: the code exists to illustrate concepts, can run slower than Python's built-in equivalents, and is indexed in DIRECTORY.md for browsing. It's MIT licensed and available on GitHub.
MarkItDown is Microsoft's open-source Python library for converting PDF, Office, image, audio, and web files into Markdown, aimed at LLM and RAG pipelines rather than human-facing formatting.

rust-lang/rust is the main source code repository for the Rust programming language, according to its own README: it holds the compiler, the standard library, and the project's documentation together in one place. The README frames Rust around three points: performance suited to critical services and embedded devices, reliability from a type system and ownership model that catch memory and thread-safety bugs at compile time, and productivity through tooling like Cargo, rustfmt, Clippy, and rust-analyzer. It's licensed under a dual MIT/Apache-2.0 scheme with some BSD-like licensed portions, and its Rust and Cargo trademarks are owned by the Rust Foundation.
jaywcjlove/awesome-mac is a GitHub-hosted, category-by-category directory of macOS software — text editors, office suites, Markdown apps, note-taking tools, journaling apps, and more — with each entry marked by icons for open-source, freeware, App Store, or native-app status.

Node.js Best Practices, maintained at goldbergyoni/nodebestpractices, is a curated checklist of more than 80 recommendations for building Node.js applications, organized into eight categories from project architecture to Docker. Each entry combines a short recommendation with an explanation of the risk of skipping it and a link to a deeper write-up, rather than being a plain list of links.
Playwright is Microsoft's framework for automating and testing the web, hosted at microsoft/playwright under an Apache-2.0 license.

It works across Bash, Zsh, Fish, and other shells by intercepting errors and running pattern-matched fixes. Setup requires adding an alias to your shell config and running `pip install thefuck`. Power users can disable confirmation prompts or enable recursive correction mode.
Java Design Patterns is an open-source GitHub project by iluwatar that documents design patterns as commented, working Java code rather than diagrams or prose.

Caddy is an HTTP/1-2-3 web server, written in Go, which provides automatic HTTPS by default, utilizing services like ZeroSSL and Let's Encrypt for public names or a local CA for internal ones. It supports flexible configuration through its native JSON API, a Caddyfile, or various other formats via config adapters. The project highlights a modular architecture for extensibility, runs on multiple platforms without external dependencies, and benefits from Go's memory safety features. The README indicates it has served trillions of requests and managed millions of TLS certificates, scaling to hundreds of thousands of sites in production. Caddy began development in 2014 and was an early adopter of automatic HTTPS by default.
