BePurple (p0)
p0: a desktop app that orchestrates coding agents to bring software development in-house.
BePurple, Inc. makes p0, a desktop app for macOS and Windows that turns a feature description into a spec and mockups and then orchestrates coding agents to build it. It runs on Claude Code or Codex, and on any endpoint compatible with the Anthropic Messages API, such as Kimi, DeepSeek, GLM or OpenRouter. It splits work into phases, runs agents in parallel with file ownership in isolated Git worktrees, and uses QA agents to check acceptance criteria before a PR opens. It also generates codebase Standards and has a Custom Agents Studio. Code generation runs locally, and model usage is billed by the user's provider.
