<p>There are great products like <a href=https://codepen.io/ target=_blank rel="noopener noreferrer">CodePen</a>, <a href=https://jsfiddle.net/ target=_blank rel="noopener noreferrer">JSFiddle</a>, <a href=https://jsbin.com/ target=_blank rel="noopener noreferrer">JS Bin</a>, <a href=https://codesandbox.io/ target=_blank rel="noopener noreferrer">CodeSandbox</a>, <a href=https://replit.com/ target=_blank rel="noopener noreferrer">Replit</a> and many others, which LiveCodes does not aim to replace or compete with. On the contrary, it aims to <a href=/docs/features/integrations>integrate</a> with as many of these services as their APIs allow.</p>
<h2 class="anchor anchorWithStickyNavbar_LWe7" id=what-makes-livecodes-different>What makes LiveCodes different?<a href=#what-makes-livecodes-different class=hash-link aria-label="Direct link to What makes LiveCodes different?" title="Direct link to What makes LiveCodes different?"></a></h2>
<h3 class="anchor anchorWithStickyNavbar_LWe7" id=language-support>Language Support<a href=#language-support class=hash-link aria-label="Direct link to Language Support" title="Direct link to Language Support"></a></h3>
<p>Currently, there are 90+ languages/frameworks supported. These include:</p>
<ul>
<li>Web languages (HTML, CSS & JavaScript).</li>
<li>Web frameworks/libraries (e.g. React JSX/TSX, Vue SFC, Svelte SFC, Solid, MDX, Astro).</li>
<li>Languages that transpile to JavaScript (e.g. TypeScript, CoffeeScript, LiveScript, ReScript).</li>
<li>Languages/frameworks that generate CSS (e.g. SCSS, Less, Stylus, Tailwind CSS, UnoCSS).</li>
<li>CSS processors (e.g. PostCSS, Autoprefixer, Lightning CSS, CSS Modules, cssnano).</li>
<li>Traditional programming languages (e.g. Python, Ruby, Go, PHP, C++, R, Lua, Scheme, Perl).</li>
<li>Data manipulation/logic languages (e.g. SQL, Prolog).</li>
<li>Authoring/templating languages (e.g Markdown, AsciiDoc, Pug, Handlebars, Haml).</li>
<li>Low-code/visual editors (e.g. blockly, rich text editor).</li>
<li>Modeling languages/diagram-as-code (e.g. Gnuplot, Graphviz, Mermaid, Vega, Plotly).</li>
<li>Languages that target WebAssembly (e.g. AssemblyScript, WebAssembly Text Format).</li>
<li>... and many more.</li>
</ul>
<p>For a full list check the <a href=/docs/languages/>Languages</a> section.</p>
<p>Generally, if you are a developer (or want to be one), there is a big chance you will find something interesting to do with LiveCodes.</p>
<h3 class="anchor anchorWithStickyNavbar_LWe7" id=client-side>Client-Side!<a href=#client-side class=hash-link aria-label="Direct link to Client-Side!" title="Direct link to Client-Side!"></a></h3>
<p>All processing and code transformations run in the browser on the client-side. After the initial load, the app gets significantly faster without having to wait for server rounds. Lazy-loading is heavily used. Only parts of the app required for the selected languages/features are downloaded.</p>
<p>The code you write in LiveCodes does not leave your computer. All projects are private unless you choose to share/export/deploy them.</p>
<p>Being a client-side app allows it to be hosted on any static file server or CDN, which removes the high requirements needed by other alternatives (like server storage or memory). This makes LiveCodes available for a large number of developers without requiring them to pay for servers, so it can stay free with unlimited usage 😊.</p>
<h3 class="anchor anchorWithStickyNavbar_LWe7" id=developer-tool>Developer Tool<a href=#developer-tool class=hash-link aria-label="Direct link to Developer Tool" title="Direct link to Developer Tool"></a></h3>
<p>LiveCodes aims to be a feature-rich, easy to use playground that can be used for prototyping and education. The other main goal (in fact, that was the motive for its development), is to allow library developers to use it for documentation of their libraries and showcase their products. This can be achieved by <a href=/docs/features/embeds>embedding playgrounds</a> in blogs, tutorials, documentation and educational websites. In addition, private (unpublished) modules can be imported with editor auto-completion and <a href=/docs/features/intellisense>IntelliSense</a>.</p>
<p>That can be done using the official app (<a href=https://livecodes.io target=_blank rel="noopener noreferrer">livecodes.io</a>), or as a <a href=/docs/features/self-hosting>self-hosted</a> option. Again, being a client-side-only app, LiveCodes becomes more convenient for not needing special server requirements, while features like export and deploy are provided by APIs of external services.</p>
<p>LiveCodes does NOT aim to be a social coding platform. It will stay as a backendless developer tool. Other platforms are already doing a great job in this regards.</p>
<h3 class="anchor anchorWithStickyNavbar_LWe7" id=build-free-development-environment>Build-Free Development Environment<a href=#build-free-development-environment class=hash-link aria-label="Direct link to Build-Free Development Environment" title="Direct link to Build-Free Development Environment"></a></h3>
<p>LiveCodes provides many of the tools you may already be using. These include Monaco editor (that powers <a href=https://code.visualstudio.com/ target=_blank rel="noopener noreferrer">VS Code</a>), <a href=https://prettier.io/ target=_blank rel="noopener noreferrer">Prettier</a>, <a href=https://emmet.io/ target=_blank rel="noopener noreferrer">Emmet</a>, <a href=https://babeljs.io/ target=_blank rel="noopener noreferrer">Babel</a>, <a href=https://www.typescriptlang.org/ target=_blank rel="noopener noreferrer">TypeScript</a>, <a href=https://sass-lang.com/ target=_blank rel="noopener noreferrer">SCSS</a>, <a href=https://lesscss.org/ target=_blank rel="noopener noreferrer">Less</a>, <a href=https://postcss.org/ target=_blank rel="noopener noreferrer">PostCSS</a>, <a href=https://jestjs.io/ target=_blank rel="noopener noreferrer">Jest</a> and <a href=https://testing-library.com/ target=_blank rel="noopener noreferrer">Testing Library</a>, among others. <a href=/docs/features/module-resolution>NPM modules</a> can be imported as usual. All these tools run seamlessly in the browser without any explicit build step. It feels like a very light-weight version of your own local development environment with the keyboard shortcuts, IntelliSense and code navigation features.</p>
<p>It just works™ without having to <code>npm install</code> anything. Not even on the server (because there is no server!).</p>
<p>This can markedly improve productivity, reduce the mental load required for all the traditional setup and can significantly decrease the barrier to entry for learning new technologies.</p>
<h3 class="anchor anchorWithStickyNavbar_LWe7" id=web-platform>Web Platform<a href=#web-platform class=hash-link aria-label="Direct link to Web Platform" title="Direct link to Web Platform"></a></h3>
<p>The output of code written in LiveCodes is a <a href=/docs/features/result>web page</a>. Whatever language/syntax you use, the result can ultimately be viewed as a web page which you can interact with, <a href=/docs/features/tests>test</a>, <a href=/docs/features/share>share</a> or <a href=/docs/features/deploy>deploy</a>. Check the <a href="https://livecodes.io?screen=new" target=_blank rel="noopener noreferrer">starter templates</a> for examples.</p>
<p>Of course, the app can be still used as a REPL with the output seen in the integrated <a href=/docs/features/console>console</a>.</p>
<h3 class="anchor anchorWithStickyNavbar_LWe7" id=powerful-sdk>Powerful SDK<a href=#powerful-sdk class=hash-link aria-label="Direct link to Powerful SDK" title="Direct link to Powerful SDK"></a></h3>
<p>The LiveCodes app (<a href=/docs/getting-started#standalone-app>standalone</a> or <a href=/docs/features/self-hosting>self-hosted</a>) can be <a href=/docs/features/embeds>embedded</a> in any web page. A powerful <a href=/docs/sdk/>SDK</a> allows the embedding page to interact with the playground (e.g. run, get/set source code, format, get result page or compiled code, get share URL, listen to changes, run tests, get test results, change layout, etc.). This enables other apps to be built on top of LiveCodes.</p>
<p>Your imagination is the limit!</p>
