OneCompiler: Code Editor IDE

OneCompiler is an online compiler that helps users to write, run and share code online. The way we learn programming has changed drastically over the past few years. Users are using mobile devices, tablets, Chromebooks, etc., to learn programming. Unfortunately, the majority of programming languages support only x86 architectures, so they are limited to being installed on Laptops & Desktops. Installations are not easy and add a steep learning curve for beginners. OneCompiler removes all these struggles & limitations by providing an online compiler platform. It's so fast that it feels like it's running locally. We run your code on powerful cloud servers with a horizontally scalable architecture to achieve cutting-edge speed. BUILD APPS AND WEBSITES WITH AI OneCompiler also helps you build complete apps and websites with AI. Describe what you want in plain English, and the AI app builder generates the code for you. You can then edit it, refine it visually, and publish it to a live URL with free hosting built in — no setup, no server configuration, no separate tools. Whether you're prototyping an idea, building a portfolio project or shipping a side project, vibe coding on OneCompiler takes you from a prompt to a working, shareable app in minutes. AI-generated code is a starting point, so review it before you ship. BUILT FOR CODING ON YOUR PHONE Practice programming on the bus, finish an assignment without a laptop, or test a quick snippet anywhere. OneCompiler runs well on low-end and older Android devices because your code compiles on our cloud servers, not on your device — so nothing slows your phone down and nothing takes up your storage. 100+ PROGRAMMING LANGUAGES OneCompiler supports more than 100+ programming/web/database languages including all popular languages like Java, Python, C, C++, NodeJS, Javascript, Groovy, Jshell & Haskell, TCL, Lua, Ada, Common Lisp, D Language, Elixir, Erlang, F#, Fortran, Assembly, Scala, Php, Python2, C#, Perl, Ruby, Go, R, VB.net, Racket, Ocaml, MySQL, SQLServer, Oracle, PL/SQL, PostgreSQL, HTML, React, Angular and many more.
