Keiko 0.3.1

Keiko's first public download release. Pick your platform below, unzip, and start it —
Node.js and the OpenCode sidecar are already inside; nothing else has to be installed.

Unsigned evaluation build (ADR-0121 D1, ADR-0163 D9). The bundles are sealed, so macOS
will not report a damaged app, but they carry no Apple Developer ID, no notarization and no
Windows trusted publisher yet. That is why the first launch needs the one extra confirmation
described below. Every integrity digest, containment and provenance check stays enforced.

Keiko 0.3.1 Release Notes

Normal · Fixes

  • First public download release: unsigned evaluation bundles for macOS (Apple Silicon and Intel) and Windows, with Node.js and the OpenCode sidecar included. macOS needs one right-click - Open on first launch; Windows shows the SmartScreen notice.
  • Load an existing keiko.config.json directly in the setup dialog instead of typing every field.
  • Upgrading from 0.3.0 needs no migration. If an older Keiko is still running it holds the local port; stop it or start this one with --port.

Install on macOS

  1. Download and unzip; double-click Keiko.app inside the extracted folder (moving it to
    /Applications first also works — the first start adopts it there).
  2. macOS will say it cannot verify the developer. Open System Settings → Privacy &
    Security    , scroll to Security, click Open Anyway, and confirm. One time only.
  3. Keiko installs itself to /Applications, starts, and opens at http://127.0.0.1:1983.

If a start fails, Keiko now says why in a dialog. Runbook:
macOS first-launch

Install on Windows

Run keiko-windows-x64-setup.exe (SmartScreen: More info → Run anyway), or unzip and start
Keiko.exe.
