Halo runs your code on a global edge network. You hand us a git repo or a `halo deploy` command; we hand back a URL, an HTTPS certificate, and a deployment that survives traffic spikes without you doing anything.

## What you get

    Push to `main`, ship to production. Every PR gets a preview URL.

  </Card>

## How it fits

Halo is the layer between your code and your users. You keep writing code the way you do today — Halo handles the edge, the cache, the certs, the rollbacks, and the autoscaling.

<Steps>
  <Step title="Connect a repo">
    Or run `halo init` against a local project.
  </Step>
  <Step title="Push a commit">
    Halo builds, deploys, and gives you a unique URL per deployment.
  </Step>
  <Step title="Promote to production">
    Aliases the deployment to your production domain. Rollback is instant.
  </Step>
</Steps>

  New here? The [quickstart](/quickstart) takes about two minutes from `npx halo` to a live URL.
