Below are the 10 closest, ranked by how many tasks and sub-tasks they share with Codewhale, then by GitHub stars.
- 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 41,093).
- 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 has more GitHub stars (150,707 vs 41,093).
- 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. Consider it because it is ready to use without building anything; it also covers computer and desktop control and MCP servers; it has more GitHub stars (145,685 vs 41,093).
- 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 41,093).
- Gemini CLI (Open source): Google's open-source terminal agent powered by Gemini. Consider it because it has more GitHub stars (107,334 vs 41,093).
- 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; it has more GitHub stars (68,591 vs 41,093).
- Open Code Review (Open source): Alibaba's AI code review CLI that combines deterministic pipelines with an LLM agent to post line-level comments on Git diffs, using OpenAI or Anthropic models. Consider it because it also covers code review; it has more GitHub stars (47,560 vs 41,093).
- Oh My Pi (Open source): Terminal coding agent with IDE features wired in, from Stencil Labs. Consider it because it also covers IDE and editor agents.
- Repomix (Open source): CLI and web tool that packs an entire repository into a single AI-friendly file (with an MCP server) so coding agents and LLMs get full codebase context. Consider it because it also covers codebase context and code search and MCP servers.
- Crush (Source-available): Charm's terminal coding agent with a polished TUI, multiple models and MCP support. Consider it because it does the same job with a different approach (source-available).
