Dupo, the agent app

Plans the work, breaks it into steps, prompts Claude Code or Codex, checks what comes back and follows up until it ships.

Dupo doesn’t write the code itself, and it doesn’t compete with Claude Code or Codex. It runs them, and it is tuned to run them well. It asks before anything that cannot be undone, and it remembers your project between conversations.

  • PlansTurns what you asked for into a plan with steps.
  • PromptsRuns each step in Claude Code or Codex, with the context it needs.
  • ChecksReads what comes back, runs the checks and opens a preview.
  • Follows upAsks for a yes, ships it, and keeps going until it is done.
