Claude Code set the template for terminal coding agents, but it’s far from the only option — and several alternatives are free, open source, and run on the same cheap models. If you’re on Windows and want an agent that reads your repo, edits files, and runs commands without the Anthropic bill, you’ve got real choices.
This rounds up the alternatives worth your time in 2026, what each is good at, and which cheap backends they take. The recurring theme: nearly all of them accept custom OpenAI-compatible providers, so the cheap models that cut Claude Code’s cost work here too.

The alternatives worth trying first
8 tools
Codex CLI
OpenAI's official terminal coding agent.
Install / download
Best reason to try it: It is a strong fit if you already work in the OpenAI/GitHub ecosystem and want a terminal-first workflow.
OpenCode
Open-source TUI with broad provider support.
Install / download
Best reason to try it: It is the most flexible open-source terminal option when you want provider choice and a clean CLI experience.
Aider
Pair programmer that works directly with your git history.
Install / download
Best reason to try it: It is best when you want every AI edit committed, reviewed, and easy to revert.
Cline
Editor-based plan, approve, edit, and review workflow.
Install / download
Best reason to try it: It is the best Cursor-like path when you want visual diffs and approval inside VS Code.
Kilo Code
Open-source IDE agent with many model choices and team/cloud options.
Install / download
Best reason to try it: It is the current editor-agent pick if you want VS Code plus broad provider choice.
Qwen Code
Alibaba's CLI, tuned for Qwen models.
Install / download
Best reason to try it: It is best when you are already using Alibaba/Qwen models and want the native CLI path.
Crush
Customizable terminal agent with a polished TUI.
Install / download
Best reason to try it: It is the best-looking terminal option in the shortlist and works well if interface polish matters to you.
Plandex
Agent workflow aimed at long-running, multi-step plans.
Install / download
Best reason to try it: It is best for larger projects where the work spans many files and several planning steps.
Terminal agents
Codex CLI
OpenAI’s terminal agent. It supports custom providers through ~/.codex/config.toml, so it can run on DeepSeek, Qwen, or Kimi when you configure the provider correctly. The one gotcha is the wire protocol — set wire_api = "chat" for many third-party OpenAI-compatible backends. Source: openai/codex. Full walkthrough: Codex CLI custom provider setup.
OpenCode
Open-source, terminal-first, and provider-agnostic through a large provider catalog. The official install path is in the OpenCode docs, and adding a custom model is a few lines of JSON. See OpenCode custom providers.
Aider
The git-native veteran. Aider edits files and writes a commit per change, which makes it easy to review and roll back. Install it from the official Aider install docs, then point it at DeepSeek, Qwen, or a local model. See use Qwen with Aider.
VS Code extensions
Cline
A free VS Code extension that brings an agent into the editor with a plan-and-approve workflow. Install it from the Cline install docs, pick the OpenAI Compatible provider, set the base URL and key, and it runs on any cheap model. See DeepSeek with Cline in VS Code.
Kilo Code
Kilo is the current “stay in the IDE” alternative I would shortlist alongside Cline. It is open source, works in VS Code and other IDEs, and advertises hundreds of model/provider choices. Start from kilocode.ai and pick the VS Code route if you want the closest Cursor-style workflow.
Specialized picks
- Qwen Code — Alibaba’s own CLI, tuned for Qwen models and multimodal input. Source: QwenLM/qwen-code. See Qwen Code CLI on Windows.
- Crush — a customizable, visually polished terminal agent with multi-provider support. Source: charmbracelet/crush.
- Plandex — built for long-running, multi-step tasks that span many files. Source: plandex-ai/plandex.
How to choose
A quick decision guide:
- Want the closest Claude Code feel, terminal-based? OpenCode or Codex CLI.
- Want git discipline and easy rollback? Aider.
- Live in VS Code? Cline, or Kilo Code if you want broader IDE/cloud options.
- Committed to Qwen models? Qwen Code.
- Cheapest possible run cost? Any of them on DeepSeek pay-per-token — see cheapest AI coding API in 2026.
Getting started with any of them
- Pick a tool that matches where you work (terminal vs editor)
- Create an API key with a cheap provider
- Configure the OpenAI-compatible (or Anthropic) endpoint
- Test on a small task first
- On Windows, consider WSL for the terminal agents
Wrapping up
You don’t need Claude Code to get a capable coding agent on Windows. Codex CLI, OpenCode, and Aider are free, open, and terminal-native; Cline and Kilo Code bring the same power into VS Code. All of them run on the cheap models that make this worthwhile, so the real decision is workflow fit, not capability.
Compare the top three directly in Claude Code vs Codex vs OpenCode vs Aider, or jump to a setup: Codex, OpenCode, or Cline.
