Reviewer scorecard
“The best open-source alternative to Claude Code. Model-agnostic, configurable, and the git integration is solid. Perfect if you want control over your tools.”
“Best instruction-following of any model. Tool use and extended thinking are reliable. The API design is clean.”
“Free, open-source, and surprisingly capable. The trade-off vs Cursor/Claude Code is polish — it works but requires more setup and CLI comfort.”
“Claude consistently produces the most useful outputs for real work. The longer context window is a genuine advantage.”
“Aider proves that AI coding doesn't need to be locked into a proprietary IDE. The model-agnostic approach means it gets better as every LLM improves.”
“Anthropic's focus on safety without sacrificing capability is the right approach. Claude keeps getting better.”
