## What does Atlasflow run?

Containerized web applications. You connect a GitHub repository, and Atlasflow builds a container image and runs it on a [microVM](/docs/concepts/how-it-works.md). Any language or framework that runs in a container works.

## Do I need a Dockerfile?

No. If you have one, Atlasflow uses it. If you don't, it auto-detects your stack and builds it. See [Supported frameworks](/docs/guides/supported-frameworks.md).

## What port does my app need to listen on?

**Port 3000**, bound to `0.0.0.0`. Atlasflow's edge proxy forwards traffic there. See [Container requirements](/docs/guides/container-requirements.md).

## How do deployments get triggered?

Automatically, on every push to your project's [default branch](/docs/guides/configuration.md). You can also trigger a [manual redeploy](/docs/guides/redeploys.md).

## Can I deploy multiple apps from one repository?

Yes. Create one [project](/docs/concepts/projects.md) per app and set each project's [root directory](/docs/guides/monorepos.md).

## Is there a CLI?

Not today. Atlasflow is driven by Git pushes and the dashboard.

## How am I billed?

Per second, for compute, memory, storage, and traffic, with monthly included [credits](/docs/billing/usage-and-credits.md). Each [plan](/docs/billing/plans.md) has a monthly minimum.

## Do I need a paid plan to deploy?

Yes. A workspace needs an [active subscription](/docs/billing/managing-billing.md) to create deployments.

## Can I run in multiple regions?

Multi-region is available on the [Team plan](/docs/networking/regions.md). Hobby and Pro run in a single region.

## Does Atlasflow offer a managed database?

Managed database, storage, and queues are [coming soon](/docs/products.md). For now, connect to an external provider via [runtime environment variables](/docs/guides/environment-variables.md).

## How do custom domains and TLS work?

Add a domain, create the DNS records shown, and Atlasflow verifies ownership and issues TLS certificates automatically. See [Custom domains](/docs/networking/custom-domains.md).

## Where are my logs?

[Build logs](/docs/observability/build-logs.md) and [runtime logs](/docs/observability/runtime-logs.md) are on each deployment. Retention depends on your [plan](/docs/billing/plans.md).
