Dev Docs: Offline Coding Docs

Stop juggling 30 browser tabs. Dev Docs puts the official documentation for 178 programming languages, frameworks and developer tools in one fast, clean Android app. Python. JavaScript. React. Flutter. Kotlin. Docker. Kubernetes. AWS. Linux. Every page opens the real, official source — never an outdated copy, never a watered-down summary. WHY DEVELOPERS AND CS STUDENTS USE IT No sign-up. No subscription. No hunting through search results for a page you already know exists. Open the app, tap your technology, read. • Read offline — save any page to your phone and open it with no connection at all. Kotlin coroutines on the commute, React hooks on a flight, Kubernetes manifests in a server room with no signal. • Bookmark what you keep returning to, and pin your working stack to the top of the home screen. • Search all 178 sources instantly instead of scrolling. • Home screen widget — reach your pinned technologies, recent pages and saved downloads without opening the app first. • Dark mode, Material 3, and a reader built for long sessions. 178 TECHNOLOGIES ACROSS 15 CATEGORIES Languages — Python, JavaScript, TypeScript, Java, Kotlin, Swift, Go, Rust, C, C++, C#, Dart, PHP, Ruby, Scala, R, Perl, Julia, Zig, Solidity, MATLAB, Fortran, COBOL Mobile — Android, Jetpack Compose, Flutter, SwiftUI, React Native, Kotlin Multiplatform, Expo, Material 3 Frontend — React, Angular, Vue.js, Next.js, Svelte, Nuxt, Astro, Remix, Qwik, Tailwind CSS, HTML, CSS, Sass, Bootstrap, shadcn/ui, Material UI, Three.js, Vite Backend — Spring Boot, Django, Flask, FastAPI, .NET, Express, NestJS, Laravel, Ruby on Rails, Ktor, Node.js, Deno, Bun, Hono, tRPC, Fastify DevOps and Cloud — Docker, Kubernetes, AWS, Azure, Google Cloud, Terraform, Ansible, GitHub Actions, GitLab CI, Nginx, Helm, Argo CD, Podman, Prometheus, Grafana, Cloudflare Workers, Vercel Databases and APIs — PostgreSQL, MySQL, SQLite, MongoDB, Redis, SQL, GraphQL, Supabase, Prisma, Drizzle, Elasticsearch, ClickHouse, Kafka, Stripe Data Science and ML — TensorFlow, PyTorch, scikit-learn, NumPy, pandas, Polars, Keras, JAX, Matplotlib, Jupyter, Hugging Face, OpenCV, Apache Spark, Streamlit AI and LLMs — OpenAI API, Anthropic API, Google Gemini, LangChain, LangGraph, LlamaIndex, Ollama, CrewAI, Model Context Protocol, Vercel AI SDK, Pydantic AI Linux and Shell — Bash, PowerShell, Git, Arch, Ubuntu, Debian, Fedora, Kali, Red Hat, CentOS Testing — Jest, Playwright, Cypress, Vitest, PyTest, JUnit Game Dev — Unity, Godot, Unreal Engine Plus functional languages, state management, automation and vector databases.
