Claude Code
Anthropic's terminal coding agent that edits code, runs commands and handles git.
OpenAI Codex CLI
OpenAI's open-source coding agent for the terminal; also runs in the cloud.
opencode
Open-source terminal coding agent that works with many model providers.
Intelligent Terminal
Experimental fork of Windows Terminal with native integration for ACP-compatible agent CLIs.
Open Interpreter
Terminal coding agent forked from OpenAI's Codex and tuned for low-cost and open-weight models, with switchable harness modes that imitate tools like Claude Code.
Tov
Tov is an experimental programming language designed to be written by coding agents. It uses TypeScript syntax minus a few traps (no any, null or loose equality, separate int and float types, and failing calls marked with try), so agents already know how to write it, and its compiler returns machine-readable fixes the agent can apply after every edit. Programs compile to small, fast native binaries, with published benchmarks against Rust, Bun and Node. Agents can learn it from the site's llms.txt.
