## At a glance

| Dimension | Replit Agents | Bolt (StackBlitz) |
|---|---|---|
| Execution environment | **Replit Linux VM** ✓ | In-browser WebContainer |
| Stack flexibility | **Any (Node, Python, Go, etc)** ✓ | JS / TS frameworks |
| Backend + DB included | **Yes — Replit Database / Postgres** ✓ | Limited to WebContainer-compatible |
| Deploy | **Replit Deployments — one-click** ✓ | Export and host elsewhere |
| Iteration speed | Fast | **Faster — no VM cold-start** ✓ |
| Collaboration | **Real-time multiplayer code** ✓ | Solo by default |
| Cost at scale | Replit subscription + deploy | **Free tier + export** ✓ |

## Verdict

Replit Agents win for full-stack apps with serious backend, database needs, and deploy-from-the-IDE workflow. Bolt wins for in-browser iteration speed and stack flexibility. For a Python / Go / Node backend app you want to deploy, Replit. For a JS / TS frontend you'll deploy yourself, Bolt.

## When to pick which

- **Replit Agents** — Backend-heavy work, polyglot stacks, deploy-from-IDE, team collaboration.
- **Bolt (StackBlitz)** — JS / TS frontend prototyping, stack flexibility, fast iteration without VM overhead.

## FAQ

### Replit or Bolt for AI app building in 2026?
