Veyyon incorporates ideas and code from upstream and peer projects.

  • oh-my-pi (can1357/oh-my-pi), under the MIT license. Veyyon is a source fork of oh-my-pi: the TypeScript/Bun agent loop and TUI, the Rust natives (search, the shell, the PTY), the hashline edit engine, provider breadth, role routing, session-tree work, and edit ergonomics all carry forward from it. Incorporated MIT code keeps its permission notice; see the repository LICENSE.
  • codex, by OpenAI, under the Apache 2.0 license. oh-my-pi and Veyyon carry forward the codex apply_patch patch format and parts of the agent-loop shape as an independent TypeScript reimplementation, see NOTICE for exactly which files are format-compatible versus which actually vendor Apache 2.0 code (the OpenAI wire types and the Playwright ARIA-snapshot bundle do; the apply_patch parser and the Codex backend client do not).
  • OpenCode, under the MIT license. Veyyon studies its plan/build workflow, project memory, compact command, and file-context UI ideas.
  • Lossless Claw, under the MIT license. Veyyon studies its summary DAG, fresh-tail compaction, and compacted-history inspection tools.
  • command-code, by Langbase. command-code is proprietary. Veyyon only studies observable mechanisms clean-room, copying no code or bundled implementation text.
