Warp
Rust-built terminal replacement with native AI agent capabilities. Runs Claude Code, OpenAI Codex CLI, and Gemini CLI simultaneously in one interface. Pioneering the 'agentic terminal' category — distinct from editor-based AI assistants.
OpenAI Codex CLI
OpenAI Codex CLI is an open-source terminal agent that applies natural language instructions to your local codebase. Running in your terminal, it reads files, writes code, runs tests, and iterates until the task is complete — powered by OpenAI's o4-mini model.
