Make it yours

Your own boards, in your own order.

The four boards are where App Ninja starts. Add a board for whatever your team does, give it a name, a colour and a role, and its agent knows what to do there. Switch a board off when a project doesn't need it.

  • Translations

    Every text in every language, checked before release.

  • Security

    A security review of each change: secrets, access, dependencies.

  • DevOps

    Pipelines, servers and deploys, set up and kept running.

  • Testing

    End-to-end tests and a test round before it ships.

  • Docs

    The manual and the release notes, written as you build.

  • Your own board
