A browser IDE is a code editor + runtime + preview that lives entirely in the web browser — StackBlitz, CodeSandbox, Replit, Glitch, GitHub.dev, vscode.dev are 2026 leaders. Zero install, instant share via URL, increasingly AI-augmented.

Browser IDEs eliminate setup friction: open URL, see code, edit, run. Two architectures: (1) cloud VM-backed (CodeSandbox Devboxes, Replit, Gitpod, GitHub Codespaces) — full-featured but needs network, takes seconds to boot; (2) in-browser-runtime ([[webcontainer]] for Node, Pyodide for Python, WASI for arbitrary) — instant + offline but limited native support. Hybrid options (StackBlitz with WebContainer + cloud fallback). AI augmentation: Bolt + v0 + Lovable build atop WebContainer; Replit Agent generates code in cloud VMs; Claude Artifacts uses sandboxed runtime. Production trend in 2026: browser IDEs are the dominant 'try this code' surface for tutorials, doc demos, and AI-generated apps.

## When to use

- Tutorials + doc demos.
- AI-generated app demos.
- Pair programming + reviews.

## Common mistakes

- Treating browser IDE as full local replacement — heavy workloads still need local.
