This project is a cloud-based web IDE and development workspace that provides a professional code editor and execution environments directly within the browser. It functions as a browser-based code execution engine for rapid prototyping and a scalable cloud workspace for managing repositories and writing code without local environment configuration. The system features secure sandboxing for isolated development, allowing untrusted or experimental code to run in separated virtual environments. It supports both client-side execution via browser-based bundling and server-side execution through a
This repository is a comprehensive cloud-based web IDE and code execution platform that provides secure sandboxing, browser-based and server-side execution, npm package support, and live preview capabilities.
Javascript Playgrounds is a browser-based code execution engine designed for running untrusted JavaScript snippets and managing interactive playgrounds. The system isolates user-submitted code inside dedicated web workers to prevent main thread blocking and protect the host environment, while supporting dynamic module loading that fetches external libraries and third-party scripts on demand. The platform includes architectural tools for mobile device simulation, rendering application output inside configurable viewport wrappers with adjustable platform dimensions and status bar styling. Debug
JavaScript Playgrounds is a browser-based execution engine that isolates untrusted code inside web workers with dynamic module loading, matching the core intent despite lacking server-side execution features.
The sandbox-sdk is a development kit designed for building secure, isolated execution environments on a global edge network. It provides a framework for creating ephemeral, containerized workspaces that allow developers to run untrusted code, manage build tasks, and host automated scripts without compromising host system security. By leveraging a serverless runtime, the platform enables the deployment of these environments directly at the network edge to ensure low-latency performance. The platform distinguishes itself by integrating language models with sandboxed execution, facilitating the
This is a secure containerized sandbox toolkit designed to run untrusted code at the edge, though it focuses broadly on server-side execution and AI agents rather than being specifically tailored for browser-based JavaScript playgrounds.
JSBin is a collaborative JavaScript playground and online frontend sandbox for writing, executing, and debugging web code. It provides a real-time code editor and an integrated environment that instantly renders HTML, CSS, and JavaScript with a live preview. The platform is designed for live coding demonstrations and pair programming, featuring a broadcasting environment that transmits keystrokes and code changes to other users instantly. It supports real-time synchronization for multiple developers through shared live sessions and includes a transpilation tool to convert alternative programm
JSBin is an online frontend sandbox and collaborative code playground that features live code execution and an integrated editor, though it focuses primarily on browser-based frontend development rather than secure server-side isolation.
Online IDE powered by Visual Studio Code ⚡️
This online IDE provides an isolated browser-based environment for running JavaScript code and features code editor integration, though it focuses more on full project workspaces than lightweight sandboxing.
Sandbox is a cloud-based development environment that provides web-based code editing directly within the browser without requiring local machine setup. It runs full Linux development environments inside remote execution containers, supplying an isolated sandbox for each workspace to safely run interactive terminals and live application previews. The platform integrates artificial intelligence capabilities to accelerate daily coding workflows, featuring an automated code assistant that generates intelligent code completions and custom recommendations as users type. Additionally, it supports m
This cloud-based development environment provides browser-based code editing and isolated containerized workspaces, fitting the sandbox category well despite leaning more toward full IDE workspaces than lightweight code snippet execution.
A nifty javascript sandbox for node.js.
This repository is a JavaScript sandbox designed for safe execution in Node.js, fulfilling the server-side execution and code isolation aspects of your search, though it lacks browser-based execution and built-in UI editors.
