# Deploy Blnk Watch

> Deploy Blnk Watch for production using the compiled binary and the start command.

<Note>Blnk Watch is currently in beta. [Send us a message](mailto:support@blnkfinance.com)</Note>

For production deployments, install or build the Watch binary and run it with the `start` command.

This gives you the standard long-running Watch process: the HTTP service starts, and when `DB_URL` is set, Watch also runs continuous Core sync in the same process.

***

## Standard deployment

<Tabs>
  <Tab title="Direct download" icon="download">
    Use direct download to fetch and install the Watch binary on your system. No Git or Go is required for the binary itself.

    <Steps titleSize="h3">
      <Step title="Install Watch">
        Install the Watch binary without cloning the repo or building from source:

        ```bash theme={"system"}
        curl -fsSL https://blnkfinance.xyz/install/watch | bash
        ```

        This installs the `blnk-watch` binary on your machine.
      </Step>

      <Step title="Set environment variables">
        Set the environment variables Watch needs:

        ```bash .env wrap theme={"system"}
        # PostgreSQL database connection string
        DB_URL=postgres://user:password@localhost:5432/blnk?sslmode=disable

        # GitHub repo containing your .ws rule files (required when not using a local rules directory)
        WATCH_SCRIPT_GIT_REPO=https://github.com/your-org/watch-rules.git
        WATCH_SCRIPT_GIT_BRANCH=main
        ```

        See [Configuration](/watch/configuration) for the full list, including Git authentication for private repos.
      </Step>

      <Step title="Start Watch">
        Run Watch with the `start` command:

        ```bash start theme={"system"}
        blnk-watch start
        ```
      </Step>
    </Steps>
  </Tab>

  <Tab title="Build from source" icon="square-terminal">
    Build the Watch binary from the source repository. Use this when you have Go installed and want to compile locally (for example, to pin a version or run from the project directory).

    <Steps titleSize="h3">
      <Step title="Build the binary">
        From the Watch project root, build the binary:

        ```bash build theme={"system"}
        go build -o blnk-watch ./cmd/blnk-watch
        ```

        This produces a `blnk-watch` binary in the current directory.
      </Step>

      <Step title="Set environment variables">
        Set the environment variables Watch needs:

        ```bash .env wrap theme={"system"}
        DB_URL=postgres://user:password@localhost:5432/blnk?sslmode=disable
        ```

        See [Configuration](/watch/configuration) for the full list.
      </Step>

      <Step title="Start Watch">
        From the Watch project root, run the binary with the `start` command:

        ```bash start theme={"system"}
        ./blnk-watch -command=start
        ```
      </Step>
    </Steps>
  </Tab>
</Tabs>

## For PaaS deployments (Railway, Render, Fly.io, etc)

The same deployment steps apply, but you need to attach a persistent volume to the container.

Watch stores its data on disk. However, most PaaS platforms have a temporary disk that is wiped on redeploys.

To prevent this, attach a persistent volume mounted at `./blnk_watch_db` so that data survives restarts and redeploys.
