# Runtimes

> How Veryfront executes app, agent, job, and sandbox work.

Runtimes execute project work.

They are separate from environments.

Environments configure targets. Runtimes execute work for those targets.

## Choose a runtime

| Runtime                                                | Use it for                                                            |
| ------------------------------------------------------ | --------------------------------------------------------------------- |
| [Server runtime](/cloud/concepts/server-runtime)       | Long-running compute for app routes and agent runtime services.       |
| [Job runtime](/cloud/concepts/job-runtime)             | Durable background execution for tasks, workflows, and cron triggers. |
| [Sandbox runtime](/cloud/sandbox)                      | Isolated workspace sessions for commands, files, and tools.           |
| [Connected runtime](/cloud/concepts/connected-runtime) | Registered service or worker that executes agent runs.                |

## How they relate

| Runtime           | Executes                                        | Boundary                              |
| ----------------- | ----------------------------------------------- | ------------------------------------- |
| Server runtime    | App routes and hosted agent services.           | Runs deployed environments.           |
| Job runtime       | Tasks, workflows, and scheduled work.           | Records durable background execution. |
| Sandbox runtime   | Commands, files, and tool work.                 | Isolates workspace execution.         |
| Connected runtime | Agent runs from registered services or workers. | Streams events to the control plane.  |
