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.”
“One tool replacing Prettier + ESLint with massively better performance. The migration from existing configs is smooth.”
“Free, open-source, and surprisingly capable. The trade-off vs Cursor/Claude Code is polish — it works but requires more setup and CLI comfort.”
“The speed improvement is not a micro-optimization — it changes CI feedback loops and editor responsiveness.”
“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.”
“Rust-based tooling replacing JavaScript tools is the trend. Biome is the most impactful example.”
