- Tokscale (Open source): Tracks token usage across AI coding agents from your terminal. Consider it because it does the same job with a different approach (open source).
- Jevgrep (Open source): CLI that finds relevant repo files and excerpts from natural-language questions for coding agents; claims ~40% cheaper agent runs. Consider it because it does the same job with a different approach (open source).
- opencode (Open source): Open-source terminal coding agent that works with many model providers. Consider it because it has more GitHub stars (213,329 vs 84,058).
- Claude Code (Paid): Anthropic's terminal coding agent that edits code, runs commands and handles git. Consider it because it is a managed commercial product, if you'd rather not run it yourself; it also covers editing and rough cuts; it has more GitHub stars (150,707 vs 84,058).
- CC Switch (Open source): Desktop manager for Claude Code, Codex, Gemini CLI, OpenCode, OpenClaw and other coding agents that switches API providers in one click and manages MCP servers, skills and prompts.

- OpenAI Codex CLI (Open source): OpenAI's open-source coding agent for the terminal; also runs in the cloud. Consider it because it has more GitHub stars (129,112 vs 84,058).
- Pi (Open source): Minimal, extensible open-source terminal coding agent and agent toolkit from Earendil, with a multi-provider LLM API, TypeScript SDK, RPC mode and installable extensions, skills and themes. Consider it because it also covers agent frameworks and SDKs and rules, skills and config; it has more GitHub stars (116,073 vs 84,058).
- Gemini CLI (Open source): Google's open-source terminal agent powered by Gemini. Consider it because it has more GitHub stars (107,334 vs 84,058).
- Understand-Anything (Open source): Turns any codebase, knowledge base or docs folder into an interactive knowledge graph you can explore and question, working inside Claude Code, Codex, Cursor, Copilot and Gemini CLI. Consider it because it also covers codebase context and code search and RAG and documents; it has more GitHub stars (87,175 vs 84,058).
- Open Interpreter (Open source): 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. Consider it because it also covers agent frameworks and SDKs.
