CodeSandbox

Open your browser, paste a link, and you’re coding with your team in seconds. Spin up a fresh project from a React, Vue, Svelte, or Vanilla template, or start a tiny sandbox to test an idea before it hits your repo. There’s nothing to install and no tooling to configure. The editor gives you smart autocompletion, error hints, and a live preview that reloads on save. Add dependencies as needed and the environment configures itself. Share the sandbox URL so anyone can run the app instantly, or embed it in tickets, docs, and design specs for quick, clickable examples.

Use it for fast iterations and collaborative editing. Invite teammates to the same file and watch their cursors move as they type. Chat in the sidebar, leave inline comments tied to code, and request changes without switching tools. Lock a sandbox to view-only for stakeholders or grant edit access to pair-program. Set breakpoints, step through code in the debugger, and inspect logs together to fix issues faster. When you’re cleaning up, rely on built-in refactoring tools (rename, extract) to keep changes safe and consistent.

Plug it into your GitHub workflow. Import a repository, branch, or pull request and start the dev server with one click—reviewers open the link and see a running app without cloning or installing. Capture snapshots to preserve states of your work, compare diffs, and roll back when needed. Experiment in a forked sandbox to validate a fix, then export changes back to GitHub as a branch or pull request. Version history inside the editor helps you track edits across sessions and contributors.

Teaching, onboarding, and bug reproduction become straightforward. Instructors hand out a sandbox link; students submit the same link with their solution. New hires follow a template to ship their first commit in minutes. QA teams create minimal reproductions and attach them to issues so maintainers can run the exact environment. Designers and engineers share component playgrounds and test UI states side by side. Drag assets into the file tree, pull packages from public registries or your private feed, and keep sensitive work private while collaborating. Build a personal template library so every new project starts with the tools and structure your team expects.
