What are we building today?

Ship with your AI agent. One step at a time.

How it works

  1. 1
    Describe the idea

    Answer seven sharp questions. Bystep writes the PRD, features and a layered backlog.

  2. 2
    Paste one prompt

    Your agent logs in via the CLI and takes tasks one at a time. Frontend on mock data first.

  3. 3
    Verify at every step

    The agent stops at each layer or phase change until you say continue.
