7 Best CodePen alternatives for Developers in 2026

If you’ve used CodePen before, you already know what it does well. You can quickly create front-end prototypes, share code snippets, and try out HTML, CSS, and JavaScript in a live environment.

But CodePen isn’t perfect for everyone.

You may need more collaboration features or a private space for client work that isn’t too expensive.

Or you’re working with frameworks like React or Vue and you want something more capable.

Whatever the reason, there are some great CodePen alternatives out there worth your time.

This guide breaks down the best options based on key features, pricing, and specific use cases so you can pick the right tool for your project.

Why Look for CodePen Alternatives?

CodePen is great for developers and technical content creators who want to experiment with code without creating files or running a local server.

However, as your projects grow, you might hit their limits.

• Limited to the front-end. No backend logic support.
• You cannot easily install full npm packages.
• Basic TypeScript support compared to modern IDEs.
• You need a paid plan to keep your work private.

If these points sound familiar, exploring websites like CodePen is the right move.

Before jumping into the list, here’s what you need to look out for:

• Language support: Does it support the languages and libraries you use?
• Collaboration features: Can your team or clients view and edit in real-time?
• Pricing: Is the free tier genuinely useful, or is it locked behind a paywall?
• Performance: Does the editor feel fast and responsive?
• Sharing: Can you easily share your work or embed it in a portfolio?

Now let’s go through the some of the better options.

CodeSandbox

If you need more than a single file editor, CodeSandbox is the industry standard. It feels like having Visual Studio Code in your browser.
