👩💻👨💻 Awesome cheatsheets for popular programming languages, frameworks and development tools. They include everything you should know in one single file.
A flat collection of cheatsheets for languages, frameworks, and dev tools — each one is a single file meant to cover the essential syntax and patterns you'd otherwise have to dig out of docs. It's aimed at developers who want a fast reference when picking up something adjacent to what they already know, not a learning path for beginners. 46k stars suggests people actually find these useful, not just star-and-forget.
Each cheatsheet is a single self-contained file, which means you can clone the repo, open one file, and never touch the internet again. The format-matches-language approach (bash cheatsheet is a .sh file with comments, Python is a .py file) means syntax highlighting works out of the box in any editor. Coverage is genuinely broad — Git, Vim, Kubernetes, Redis, and a handful of JS frameworks are all here. Active enough that Tailwind and Firebase got added after the initial push.
Freshness is a real problem — some cheatsheets (AngularJS, Feathers.js, Nanobox) cover tools that are deprecated or effectively dead. There's no version tagging on any content, so you can't tell if the Redis commands are for 5.x or 7.x. The JavaScript backend coverage is heavily biased toward the author's preferences (Sails, Feathers, Adonis) while Spring, FastAPI, Gin, and Rails are entirely missing. No tests or CI validation means incorrect syntax can sit in a file for years without anyone catching it.
