# Application sources

> The five ways to create an application in Create—upload, GitHub, GitLab, Bitbucket, or Docker image—and how they map to the API.

When you choose **Application** in **Create**, you pick a **source**: how code or an image gets into the deployment. Each option still creates an **`application`** resource; the choice is stored as **`uploadType`** / **application type** (for example `upload-app`, `github-repo`, `docker-image`).

| Menu label         | Internal id      | Typical purpose                                                                                                        |
| ------------------ | ---------------- | ---------------------------------------------------------------------------------------------------------------------- |
| **Upload app**     | `upload-app`     | Ship a **zip** or folder artifact; best when code is not in a connected Git repo.                                      |
| **GitHub repo**    | `github-repo`    | Deploy from **GitHub** (branch, path, build commands). Requires **Git** account linkage as your deployment configures. |
| **GitLab repo**    | `gitlab-repo`    | Same for **GitLab.com** or compatible GitLab.                                                                          |
| **Bitbucket repo** | `bitbucket-repo` | Same for **Bitbucket**.                                                                                                |
| **Docker image**   | `docker-image`   | Run a **container image** from a registry, or upload a **Docker image archive** where supported.                       |

**API:** Every source uses the **`application`** resource type for catalog and plan checks. The backend tells flows apart with **`applicationType`** / **`uploadType`** on the resource.
