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.”
“First-party SDK with excellent TypeScript support. Tool use and streaming work flawlessly. The agent loop is well-designed.”
“Free, open-source, and surprisingly capable. The trade-off vs Cursor/Claude Code is polish — it works but requires more setup and CLI comfort.”
“Using the official SDK reduces risk of breaking changes. The agent patterns are production-tested by Anthropic themselves.”
“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 approach to safe, capable agents sets the standard. The SDK makes best practices the default path.”
