← Alto9

Two product lines, one small team

Spec9 is for planning software when coding agents are part of the team. Kube9 is for running that software on Kubernetes once it ships. Different jobs, same people, same habit of writing things down before we build them.

Early access

Spec9

Where product and engineering meet.

Product and engineering already work closer than most org charts admit. The trouble is that the feature lives in one place, the architecture lives in another, and the agent writing the code sees neither.

Spec9 puts both in one collection. Product writes what the software should do. Engineering draws how it fits together. Then the same coding agent you already use reads that collection, builds from it, and checks its work against it.

  • The feature

    Write behavior as Given, When, Then steps in a feature tree. Tag scenarios with the personas they serve, and see the Gherkin update as you type.

  • The system

    Draw the architecture in C4. Double-click a system to drop into its containers, then again to reach the components inside.

  • The agent

    Point Cursor, Claude, or Copilot at your collection over MCP. It pulls the slice it needs, builds from it, and validates the result.

Kube9

Kubernetes tools for the people who actually run the clusters.

Start in your editor, add the rest when you want it

The VS Code extension works on its own. Add the operator for scheduled health checks, or try the desktop app if you'd rather have a dedicated IDE.
