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.”
“The most mature AI API with the largest ecosystem. Function calling, JSON mode, and assistants API cover every use case.”
“Free, open-source, and surprisingly capable. The trade-off vs Cursor/Claude Code is polish — it works but requires more setup and CLI comfort.”
“Reliability has improved significantly. The ecosystem and tooling around OpenAI's API remain unmatched.”
“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.”
“OpenAI set the standard for AI APIs. The Assistants API and real-time API point toward increasingly capable agent platforms.”
