## When to reach for it

- You are choosing a runtime & deploy component — how you run it.
- You are happy to depend on a hosted service and would rather not operate this yourself.

## Alternatives in the runtime & deploy layer

| Option | What it does | Licence | Self-host |
| --- | --- | --- | --- |
| Docker Compose | One file, one box, everything local. The honest starting point. | open source | yes |
| Cloudflare Workers | Edge runtime with Durable Objects for long-lived, stateful agent sessions. | proprietary | no |
| Modal | Python-native serverless with GPUs and sandboxes, scale to zero. | proprietary | no |
| Fly.io | Long-running containers close to users, without owning a Kubernetes cluster. | proprietary | no |
| Temporal | Durable execution — the run survives a crash, a deploy and a week of waiting. | open source | yes |
| Centaur | Paradigm's self-hosted control plane: one shared team agent, an isolated k8s sandbox per Slack thread, and no raw API keys in the agent's environment. | open source | yes |
| Kubernetes | Your existing cluster. Nothing new for the platform team to approve. | open source | yes |

## Curated stacks using it

- Customer-facing support agent: Talks to strangers, remembers them, and is assumed hostile-adjacent by default.

```bash
curl -fsSL "https://newagent.build/api/stack?runtime=vercel&format=sh" | sh
```
