# Rocket.Chat Apps FAQ

****How can I extend my workspace’s functionality?****

There are several ways to extend Rocket.Chat, depending on your needs:

- [**Apps Marketplace:**](/v1/docs/rocketchat-marketplace) Install ready-made apps built by Rocket.Chat and third-party developers
- [**Build your own app:**](https://developer.rocket.chat/docs/rocketchat-apps-engine) Use the Apps-Engine framework to create custom functionality
- [**Integrations**](/v1/docs/integrations)**:** Use scripts or webhooks to automate actions when messages are sent or received
- [**Contribute to Rocket.Chat:**](https://developer.rocket.chat/docs/contribute-to-rocketchat) Modify the core platform by submitting pull requests (advanced use case)

You can use one or combine multiple approaches.

****Do I need to host my app separately?****

No. Rocket.Chat apps are **packaged and installed directly into your workspace**.

You can:

- Install apps from the [marketplace](/v1/docs/rocketchat-marketplace)
- Upload and install them [manually](/v1/docs/rocketchat-marketplace)

Rocket.Chat handles the integration automatically.

****Can I use apps that aren’t published in the marketplace?****

Yes. You can build and deploy **private apps** to your own workspace.

It’s recommended to use the [Apps-Engine CLI](https://developer.rocket.chat/docs/rocketchat-apps-engine) to simplify development and deployment.

Private apps are available on self-managed workspaces and on Dedicated private cloud workspaces. See the next question for cloud-hosted workspaces.

****Can I install private apps on a cloud-hosted workspace?****

Only on a Dedicated private cloud workspace. Standard cloud and Premium cloud workspaces run on shared infrastructure and do not support private app installation, regardless of your plan.

If you need a private app on a cloud-hosted workspace, contact our [Sales team](https://www.rocket.chat/sales-contact) about Dedicated private cloud. See the [Cloud hosting comparison](/v1/docs/rocketchat-cloud-hosting-service-level-agreement-sla#cloud-hosting-comparison) for the hosting tiers.

****Does Rocket.Chat provide a plugin framework?****

Rocket.Chat does not use a traditional plugin system.

Instead, it provides the [Apps-Engine framework](https://developer.rocket.chat/docs/rocketchat-apps-engine), which allows you to safely extend functionality without modifying the core codebase.

****What language should I use to build apps?****

Rocket.Chat apps are built using TypeScript.

****Is there a limit to how many apps I can install?****

- **Premium (Commercial, Government, Defense) workspaces:** No limit on the number of apps

- **Community workspaces:**
  - Up to 5 marketplace apps
  - Private apps are not supported

Refer to the [usage limits](/v1/docs/rocketchat-marketplace#app-installation-and-usage-limits-by-plans) documentation for more details.
