# Install Techstack Alpha on Windows

> Download the unsigned Techstack Windows Alpha and connect a local server

Techstack Alpha is an early, local-first Windows client for operating servers
in your home network. It can run without a hosted kombify account. StackKits on
the server still bootstraps its required local Owner/Admin identity.

<Warning>
  This is an unsigned Alpha release for real-user feedback, not a stable or
  production-readiness claim. Windows may display a SmartScreen warning. Verify
  the GitHub release origin and checksum before deciding whether to continue.
</Warning>

Compare the installer hash with
[`SHA256SUMS.txt`](https://github.com/kombifyio/TechStack/releases/latest/download/SHA256SUMS.txt)
and read the
[`UNSIGNED-WINDOWS-RELEASE.txt`](https://github.com/kombifyio/TechStack/releases/latest/download/UNSIGNED-WINDOWS-RELEASE.txt)
notice before opening the installer.

## Use Techstack locally

1. Start Techstack and choose **Use locally**. A hosted kombify account is not
   required for this mode.
2. For a fresh Ubuntu server, choose **Give me a one-liner**, select
   **Basement Kit**, and complete the local Owner/Admin bootstrap fields.
3. Copy the generated pairing command and run it once on the Ubuntu server.
   Keep the Windows client running and reachable on the local subnet while the
   server downloads its agent and sends the first Guard heartbeat.
4. Wait until Techstack changes the server from **Not connected yet** to the
   connected state, then continue with the StackKit rollout.
5. For a server that already runs Basement Kit, choose **Connect my server**
   instead and enter its local SSH details.

<Note>
  Windows Alpha `v0.7.97` bundles the pinned Basement Kit catalog, its Windows
  validator, and the Linux rollout payload. The installer also creates a
  Windows Firewall exception for TCP `5264` limited to the local subnet so the
  generated command can reach the client even when Windows classifies the home
  network as Public.
</Note>

<Note>
  Cloud sync and connected operation require a separate account later. They are
  not prerequisites for the local Alpha path.
</Note>

  Use the standalone StackKits one-liner when you want to prepare the server
  independently and attach it through **Connect my server** afterwards.
