Aider, Qwen Code CLI, and OpenCode face off in local coding assistant benchmark

By PulseAugur Editorial · [1 sources] ·

A comparison of three local command-line AI coding assistants—Aider, Qwen Code CLI, and OpenCode—reveals significant differences in setup, performance, and resource usage. Aider and OpenCode were straightforward to set up with Ollama, while Qwen Code CLI required specific configurations like a Jinja template and a larger context window to function correctly. In a test of 12 common coding tasks, Aider achieved a perfect success rate, OpenCode had one partial success, and Qwen Code CLI had two partial or failed attempts, particularly struggling with tasks requiring multi-edit reasoning.

    Qwen Code vs Aider vs OpenCode: I Ran the Same 12 Tasks Through 3 Local CLI Agents on One RTX 4070

    <p>I pointed three coding CLIs at the same local model and ran twelve tasks through each one. The model was Qwen 35B, hosted on an RTX 4070 12GB via <code>llama-server</code> with <code>--cpu-moe</code>. The tasks were mundane: build a hello.py, add a CLI flag to an existing scri…
